What pipes to make ventilation in the bath. How to make a ventilation system in a sauna with an electric heater: technical nuances

Qualitatively equipped ventilation in the bath solves two major problems:

1. providing people with the necessary amount of fresh air during procedures;
2. a quick decrease in humidity and drying of the bath after they are completed.

At the same time, the required temperature is maintained, comfortable conditions are provided, the risk of musty smell, fungus, mold is eliminated, and fuel consumption is reduced. If proper ventilation is not organized in the bath, then its wooden structures become unusable in just a couple of seasons.

Reliable ventilation of the bath protects from the effects of carbon monoxide gas during stove heating.

If necessary, ventilation can solve the problem of quickly adjusting the temperature. In some cases, sick people or children require an accelerated decrease in temperature and its further maintenance at a new level.

According to current standards, high-quality ventilation of the bath should provide an air exchange rate of 5 ... 10 room volumes per hour.

Natural or forced supply and exhaust air exchange using a fan can be used. Natural ventilation for a bath is characterized by simplicity, no energy costs, and reliability. Its feature is the obligatory presence of air inlet / outlet vents with a control damper device.

The combined version uses a fan - to intensify air exchange. For a mechanical type of ventilation, the control is carried out by humidity and temperature sensors.

Efficient ventilation - necessary in all areas of the bath

Proper ventilation for a bath should comply with the following principles:

1. when designing a bath is selected
2. arrangement of ventilation ducts, inlet and outlet vents is carried out during construction;
3. the area of ​​​​the exhaust opening necessarily exceeds the area of ​​\u200b\u200bthe inflow opening, otherwise it will not be possible to achieve access to the required amount of fresh air;
4. the calculation of the area of ​​the ventilation hole is made from the dependence of 24 cm2 of the area of ​​​​the vent per one cubic meter of the volume of the room;
5. it is forbidden to place the exhaust and inflow openings on the same straight line in order to avoid violating the correct air circulation;
6. be sure to equip the ventilation valves for the bath at the inlet and outlet openings.

The presence of adjustment of the free section of the inflow and outlet allows:

• significantly accelerate the achievement of the desired temperature of the steam room with closed ventilation;
• achieve comfortable conditions by adjusting the intensity of air exchange;
• adjust to weather conditions.

Combined ventilation in the bath requires the use of fans with a protection level of at least IP44 with a heat resistance of about 130 degrees.

Do-it-yourself ventilation in the bath - device features

correct and effective ventilation in the dressing room is organized according to the following rules:

• hourly productivity should be three times the volume of the dressing room;
• the inflow must correspond to the air outlet;
• air movement is directed from the residential area to the economic one;
• the most effective is the combined air exchange with an exhaust fan;
• the ventilation grill is arranged at a two-meter level from the ground.

Consider how ventilation is performed in the dressing room of the bath with your own hands:

1. the door from the steam room should be as close as possible to the stove to ensure a comfortable temperature regime;
2. on the opposite side of the steam room, they make an outlet 0.15x0.2 m with an adjustable damper;
3. install an axial exhaust fan;
4. the supply vent is performed at a height of half a meter above the floor;
5. under the floor of the dressing room, an air duct for the exit of hot air from the steam room is equipped, improving heating.

It is extremely important to ventilate the floor in the bath, allowing it to dry quickly and ensure the durability and reliability of the coating. Basic rules for its implementation:

• in the underground doing cement screed with a slope to the drain pipe;
• brick pedestals are used to fix the floor log;
• the foundation of the bath under the flooring should have air holes on opposite sides, but not opposite to each other;
• when laying the flooring between the boards, gaps of about 8 mm are provided;
• equip the mark of the finishing floor above the level of the blower of the furnace;
• Ventilation vents in the subfield must be provided with control dampers and protective grilles.

5 best ventilation schemes for a bath

The best results are given by the ventilation of the bath - the scheme of which corresponds to one of the five main options.

According to the first air exchange scheme:

• an air inlet is made behind the stove 50 cm above the heater mark;
• the exhaust outlet with a fan is placed on the opposite wall at a level of about 250 mm above the zero mark;
• the cold air stream warmed up by the stove goes under the ceiling, cooling down, it goes down to the hood hole;
• uniform heating of fresh air is guaranteed.

According to second scheme for air exchange:

• air supply and exhaust openings are made on the same wall opposite the furnace;
• the inflow vent is located at the bottom 200 ... 300 mm from the floor, and the hoods at the top 200 ... 300 mm below the ceiling;
• put a fan in the exhaust hole;
• in the process of circulation, the flow of cold air goes to the stove, is reflected from it upwards and under the ceiling goes to the hood.

The scheme is used when there is only one external wall used for air inlet/outlet openings.

According to the third scheme ventilation in the steam room is carried out as follows:

• the supply outlet is placed behind the stove 200 mm above the floor;
• the hood hole is placed on the opposite wall also 200 mm above the floor mark;
• to intensify the hood, a fan installed in the exhaust vent is used.

This scheme is characterized by fast, uniform air heating, freshness and comfort.

Fourth scheme used for steam rooms with a leaking floor:

• an inflow hole is made behind the heater 200 ... 300 mm above the floor;
• the air is heated, passing the heater, and falls under the floor;
• from there, the exhaust air goes up through the ventilation pipe and is discharged over the roof.

During the continuous operation of the furnace, the steam room is ventilated according to the fifth scheme:

• an air inlet is made opposite the heater on the far wall;
• air outlet is carried out through the furnace blower.

Often ventilation in the steam room of the Russian bath is performed according to the sixth scheme:

• the inflow occurs through an outlet in the lower part of the wall behind the heater;
• two exit holes are made on the opposite wall;
• exhaust holes connected flexible pipe and equipped with shutters;
• during procedures, the upper opening is closed;
• for quick ventilation and drying of the steam room, both vents open.

Given the sensitivity of wood to high humidity, for ventilation of a bath from a bar is necessary:

Features of sauna ventilation

While the principles are similar, sauna ventilation has some peculiarities. For various premises saunas, the following air exchange rates are recommended:

• shower room - 50;
• massage room - 5;
• steam room - 5;
• rest room - 3.

Air supply and exhaust openings located on opposite walls are spaced diagonally.

Most often, ventilation for a sauna is performed according to two schemes:

1. Includes an air inlet behind the stove above the floor. From the opposite wall, two exit holes are made connected by a ventilation duct. The first outlet is made 100 cm above the floor, and the second below the ceiling. This arrangement improves the uniformity of air exchange throughout the volume of the steam room.
2. Provides a supply outlet at the furnace slightly above its level. The hood hole in the opposite wall is arranged 50 cm lower. For efficient exhaust, a fan is installed at the outlet.

The sauna is a great place to spend your free time, as well as to improve your health.

However, a quality stay in it can only be ensured through ventilation.

During the construction of the steam room, a special role is always given to the correct ventilation of the sauna.

This is explained by such reasons:

• Provides fresh air supply.
• It is she who is capable distribute oxygen throughout the room heat it evenly and evenly.
• Will help speed up cleansing of accumulated carbon dioxide, which will facilitate the process of staying in such a space.
• Due to the ventilation in the steam room, proper air circulation, which avoids excessive moisture settling on all wooden surfaces. As a result, the tree will last longer, it will not be covered with a layer of mold and fungus harmful to the human body, and will not rot.
• Correct the operation of the furnace is also directly dependent on air exchange.
• Eliminates the chance of suffocation, because quite often a group of people gather in the steam room who can drink alcohol to improve their mood. Without an influx of fresh air, after 30 minutes it will be almost impossible to breathe in such a room.
• The entire room can be well ventilated and thoroughly dried, which is important for a comfortable stay in it.

Paying attention to all the above arguments, and asking yourself the question:

Is ventilation necessary in a sauna? There is, of course, an unequivocal answer - yes!

The main thing is to do it in a timely and correct manner in order to avoid the processes of wood decay, the presence of drafts and an unpleasant smell in the future, which will not please the visitors of the steam room.

Proper ventilation of the sauna or bath

Access to fresh air and maintaining a constant, high temperature can only be achieved through the presence of ventilation in the Finnish sauna. It cannot exist without extract and inflow.

The extract in the sauna is needed to remove carbon dioxide from it, and the inflow creates all the conditions for pure oxygen to enter the room.

Before you start construction, you need to know about the unchanging rules and regulations for creating it in the bath.

• After 25-30 minutes of the sauna, it often becomes difficult to breathe in it, the head begins to spin and hurt. The reason for this lies in the fact that there is an incorrect change of musty air filled with steam and human sweat. According to SNIP, the air in such enclosed spaces must be updated at least 5-6 times per hour. At the same time, its speed can be at least 20 cubic meters for 60 minutes.
• The chimney should not be very narrow. It is better to make its diameter the same as that of the supply one.
• Inlet openings may only be placed at the bottom. The permissible height from the floor cannot be less than 20 cm. Install it strictly behind the stove. Otherwise cold air will not have time to heat up, which will entail the presence of drafts and uncomfortable sensations of people staying in such an enclosed space.
• To know which pipes with which section you need to purchase, you should take into account certain norms and rules: for 1 cubic meter of the equipped room, there must be a pipe with a cross section of at least 24 centimeters.
• The intake and exhaust openings must not be opposite each other..
• It is imperative to think about the possibility of adjusting the air flow, reducing or increasing it. This can be done through valves that are installed in the vents of the bath.
• Often in the sauna leave a gap between the bottom of the door and the floor due to the absence of a threshold or its very low height. It is needed for natural exhaust in the Finnish sauna.

The scheme of oxygen movement will look correct only if there is more than one hood in the room in question. Paying attention to where the inflow is located, strictly on the opposite side of it at a height of up to one meta, the first exhaust hole is equipped. The second must be done directly under the ceiling. The main thing at this stage of work is to connect both holes with a single box leading to the chimney or a common exhaust duct.

Consider the principle of operation of the Finnish sauna:

1. Before starting the steam room, it should be thoroughly ventilated, which will freshen the air.
2. Close the outlets and doors with the help of valves, which will allow the air in the steam room to heat up quite quickly.
3. The inlet valve remains open. This is done in order to avoid air discharge.
4. After waiting for the room to warm up completely, we monitor the proper ventilation in the sauna. To do this, slightly open the lower channel. Thus begins the gradual movement of oxygen. At the same time, it must be remembered that the upper channel should not be opened so as not to miss well-heated air from the bath. Fresh, cool air, after entering through the supply duct, slowly warms up due to the furnace and immediately begins to gradually displace the air that has already stagnated.

Such a system for people will not be noticeable if its preliminary installation is performed correctly, adhering to all the advice and recommendations of specialists. Being in it, vacationers will not even feel discomfort and will enjoy a pleasant temperature and comfortable humidity.

An equally important role is played by the stove, which is equipped either in the steam room or in a separate room. It is made of metal and lined with brick on the outside. Performs the following functions in the sauna:

• Heats the overall area of ​​the room.
• Heats up water.
• Produces steam.

When choosing this device, you should be guided by the following criteria:

• Size - great if the oven is small, which will save space.
• Must be reliable and secure.
• Have the ability to heat up quickly.
• Have a low cost.
• It must have a long shelf life in order to constantly withstand heavy loads and temperature changes.
• When choosing a stove, first of all, consider its power and size relative to the size of the sauna.

Kinds

To date, there are three types of ventilation in the sauna. Let's consider each of them in more detail.

Natural

Occurs due to pressure differences indoors and outdoors. Differs in small expenses for installation works, and also simplicity in operation. This is done in the following ways:

• Due to the wind pressure, which is possible only in buildings made of logs. The air pressure inside the room occurs due to powerful gusts of wind, which create a significant air discharge on the leeward side. The movement of air in and out occurs through the gaps between the logs.

The disadvantage of this type of ventilation is that it is impossible to regulate it, which directly affects the temperature inside the bath.

As a result of strong winds, drafts are possible, which also causes no less inconvenience for vacationers.

• thanks to aeration. Its meaning lies in the penetration of air masses directly from the street through the bottom of the room, in which there are special vents. Outdoor air, getting into the sauna, squeezes out a hot stream from above and directs them into the duct. This sauna ventilation system is perfect for rooms with very hot air and a lot of steam. Oxygen circulation here is very fast.

Mechanical

Settled only when supply ventilation you can't do it in a sauna. That is why it is also called forced. It consists of rather expensive elements: coolers, heaters, fans and air filters.

To achieve the exit of the treated air from the room, with forced ventilation in the sauna, exhaust fans on which filters must be mounted.

This type of ventilation is used in very large rooms where there are pools, showers and a huge number of visitors. It makes the air clean from steam, sweat and unpleasant odors in a short time.

Using mechanical ventilation, a forced supply of oxygen is used. This is achieved through a very complex system that has the following components:

• supply chamber.
• Mechanisms that reduce the amount of noise.
• Diffusers.
• Check valves.
• Distribution grids.

In order for the supply air to be comfortable when it enters the room, it is pre-cleaned and heated.

Combined

It is used in baths only if this is due directly to the peculiarities of their structure. So, a sauna located in a house and bordered by three of its walls with common housing cannot have natural ventilation. At the same time, it will not be possible to arrange the inlet and outlet holes according to all the rules. Therefore, observing the norms, it is allowed to equip the inlet at a height of at least 20 cm from the floor, and the exhaust is placed on the same wall at a similar distance from the ceiling.

The principle of operation of such air exchange is that cold air enters the room, passes through the stove, heats up and circulates throughout the sauna.

Be sure to install valves on all openings that regulate the flow.

The disadvantage of such a system is the rather strong speed and amount of air masses.

In some cases, the supply channel is mounted not under the heater, but above it. The outlet is then placed on the opposite side a few centimeters higher. So it will be possible to reduce the air flow, but there is an insufficient amount of rice. To avoid this, a fan is additionally installed in the outlet channel.

Ventilation system diagrams

There are three device schemes:

• high-speed consists in installing the supply channel strictly behind the stove at a level of 20 cm from the floor. Be sure to place an exhaust hole on the opposite wall at the same distance, inside which a fan is placed.

Outdoor air, getting into the room, instantly warms up due to the stove already red-hot at that time. Then he rises to the ceiling, cools down a little, lowers down and is taken out of the bath. Thanks to this air flow, the temperature that is most comfortable for the human body is achieved, because all air masses are mixed gradually and evenly.

• If the sauna is located inside an existing room and she has only one wall bordering the street, the inlet and outlet channels are mounted on this surface. Main conditions: they are located at the same distance from the floor and ceiling (20 cm) directly opposite the stove. So, at the top there is a forced outflow, and at the bottom - an inflow.

With this scheme, the air, entering the room, immediately goes to the furnace and gradually heats up, after which it is brought out.

• The most gentle heating of air masses is achieved through the use of this scheme. Its principle is to locate the inlet behind the stove at a height of 60 cm from the floor, and the outlet with a fan just on the opposite wall at a height of 20 cm from the floor.

Outdoor oxygen, penetrating into the room, heats up and rises. Already slightly cooled air masses leave the building. Due to the slower flow, staying in such a sauna becomes very comfortable.

Sauna ventilation device

When planning to make ventilation in the sauna with your own hands, you should not forget that you need to ensure high-quality air exchange of the floor of this room. Otherwise the room will quickly become unusable, and the floor covering will not be able to last more than 3 years.

Floor ventilation involves the following stages:

1. During construction concrete base install vents on opposite walls of the basement. If the foundation has already been built, then any interference with its integrity can significantly affect the quality of the entire structure.
2. In opposite walls, cut through holes for air to enter, which are recommended to be covered with metal bars. This will prevent various rodents and insects from entering the room.
3. When equipping the stove, the blower should be slightly lower than the top level of the floor, which will allow it to work as a hood.
4. When installing floor boards, it is necessary to leave small gaps between them, the size of which should not exceed 10 mm. This will allow the water to naturally exit through the floor.

Consider how to make ventilation in the sauna, depending on its location.

Ventilation in a sauna with an electric heater:

• Under the door, a gap of high-rise buildings up to 5 cm must be left.
• The inlet channel is placed under the stove.
• Exit holes are made on the opposite wall: one above the floor, the other under the ceiling.
• For proper operation, the holes are connected by a duct that leads into the chimney or the entire ventilation system of the house.
• Gates are installed on the air ducts, which makes it possible to regulate the flow.

Ventilation of a sauna in a private house requires the presence of an ideal waterproofing material in such a room.

Most often it is placed near the bathroom, because it already has its own hood, which facilitates the process of connecting two air exchanges.

The ventilation in the sauna in the basement is connected via channels to the general system of the house. In such versions of the baths, an electric stove is installed on the floor or hung on the wall.

• Do not forget about the ventilation errors in the home sauna:
• Air duct schemes need to be thought out in advance.
• Lack of clearance under the door and air inlet can lead to suffocation.
• Creating a hole only for air outflow leads to the absence of air circulation.
• Lack of valves results in an inability to regulate the flow.
• The inlet and outlet channels are placed opposite each other at the same level, which leads to the presence of drafts.
• Expensive equipment should not be used for ventilation, because constant temperature fluctuations will quickly require repair and possibly renewal of some components.

How much does it cost

When planning to make ventilation in the sauna with your own hands, you need to know that its cost will cost about 24-38 thousand rubles. Everything will depend on the cost of components.

• The ventilation valve can be purchased for 650-1500 rubles.
• Lattice for 300-400 rubles.
• Supply and exhaust system for 18500 rubles.

Creating a high-quality air exchange system is an important part of the operation of the sauna, so it is necessary to approach the choice of its components, as well as the installation process, thoughtfully and in a timely manner.

Ventilation in the bath is essential. First of all, ventilation is designed to ensure the safety of people who take bath procedures.

Everyone knows that when breathing, a person inhales oxygen, and exhales carbon dioxide. In a tightly closed room, he will begin to suffocate after a while. And in the steam room, where the temperature is high and the concentration of water vapor, this will begin to happen even faster.

Relaxing on a shelf, there is no time to get to the saving one. The price of the wrong ventilation device can be too high.

The second important factor is the decay of the tree. Enjoying bath procedures and benefiting from them, smelling rot and mold, is very problematic. Therefore, proper ventilation in a Russian bath is a guarantee not only of its benefits, but also of the health of vacationers.

In the photo - rotting wood with insufficient drying of the tree

Experts believe that such a ventilation device in the bath can be considered correct, in which the air in the room is replaced three times in one hour. The ventilation scheme in the bath is selected depending on the type of structure and materials used in the construction of the walls.

General principles of ventilation in the bath

The correct arrangement of the bath and ventilation in it, regardless of the type of structure, is based on the following basic principles:

• Fresh air that enters the steam room should not violate its temperature regime;
• The already exhausted air, which contains the most carbon dioxide, should be removed from the room;
• The location of the air in the steam room should be layered: the hottest - under the ceiling, on the bench - the most comfortable and cold - near the floor.

Note!
There should be no draft in the steam room!

If all these principles are followed, then bath procedures will bring the maximum effect for which they are calculated - the restoration of mental and physical strength.

Ventilation device in a free-standing wooden bath

The tree is considered ideal building material for a bath. wooden walls"breathe", so the issue of air exchange is partially solved in a natural way.

However, even in a wooden building in a steam room, ventilation is necessary. At least for quick drying of the tree after taking bath procedures.

Work plays an important role in air exchange processes. sauna stove. When water is poured on, a column of hot steam is created, which rises up. As it cools, it lowers, pushing the used air out of the steam room.

Together, the above factors allow you to create the necessary humidity and temperature in the steam room, and ensure normal air circulation.

Let us consider in more detail the ventilation device in wooden baths. The main tasks for us, of course, will be to ensure the inflow of fresh air and the removal of already exhausted air. Our instructions will help you cope with these tasks.

Ensuring air flow

The correct frame is laid in such a way that the lower crowns are free. With this installation, it is possible to access fresh air from the street.

In addition, in any case, there will be gaps around the steam room door that are sufficient for it to enter. The stove in such baths is placed closer to the door so that it immediately heats up.

If the steam room is designed for 6 or more people, a separate air duct is brought to the heater, which supports the combustion process. If you make this duct double, then the problem of fresh air supply is solved once and for all.

Exhaust air removal

If the heater is heated directly from the steam room, then the exhaust air is ejected through the furnace into. If the oven is properly installed, no additional holes are required.

In order to dry the room after the end of the bath procedures, a small hole can be cut in the wall (up to 200x200 mm). At the time of heating and work of the steam room, it is closed with a special plug.

If there is a window in the steam room, such a hole is not needed. Sometimes a window from the steam room is cut through into the washing room, and either a through hole to the street or another window is already made in the washing room. Thus, when drying, two birds with one stone are immediately killed, both the steam room and the washing room are dried.

Thus, the myth that wooden bath ventilation is not needed, confirmed when the following conditions are met:

• The steam room is calculated for 2-4 people;
• The lower crowns of the log house are laid freely;
• The stove-heater is heated directly from the steam room;
• There is a hole or window in the wall for ventilation.

Actually, such family baths are usually built on personal plots.

Ventilation device in a free-standing brick bath

A brick structure, as well as a structure made of foam concrete, expanded clay blocks and other capital structures, is another matter. Ventilation in brick bath more complex.

The first difference is that the floors in a brick building must be ventilated. The thing is that the floors in the bath are constantly in contact with water, and if they are deaf, then you will have to change the boards about once every three to four years. You can not even talk about unpleasant odors and mold.

The ventilation of the floor in the bath is laid even at the stage of foundation construction. To do this, special holes are made in the foundation on opposite sides. These holes will provide through air circulation under the floor and dry the log.

The second difference is the obligatory presence in the steam room of special supply and exhaust openings. There may be several. Two air inlets are made at floor level and covered with bars so that rodents do not penetrate.

There are 4 most popular schemes for the ventilation device in the bath, from which you can choose the most suitable for you.

• Scheme No. 1. The air inlet is located behind the stove at a distance of 50 cm from the floor. An exhaust hole is cut in the opposite wall no higher than 30 cm from the floor. A bath fan is installed on it, which will circulate air.

According to this scheme, the air in the steam room is heated evenly, the incoming air is heated from the stove and rises. Cooling, it goes down and exits through the outlet. The lower it is located, the stronger the air flow will be. When using a fan, a ventilation valve can be installed on the outlet.

• Scheme No. 2. Suitable for those baths where the stove is heated from the steam room. In this case, the inflow is done directly under the stove. The flow of fresh air is sucked in by the stove, supporting combustion, and provides an inflow directly into the room.

The exhaust hole is located above the floor and a corrugated pipe is connected to it, which rises up to the level of the roof and goes outside. In other cases, the ventilation duct is made in the wall.

Note!
If the walls of the bath are made of expanded clay concrete blocks, then it is best to lay the ventilation ducts during construction.

• Scheme No. 3. According to this scheme, ventilation for the bath is arranged through cracks in the floor. In this case, the supply hole is made in the wall near the stove at a height of 30-50 cm from the floor. The air, heated up, rises and exits through the cracks between the floorboards into the basement. From the basement space, it is thrown out with the help of a special pipe.

Note! For the normal functioning of this type of ventilation, it is necessary to leave gaps between the floorboards of 5-10 mm.

• Scheme No. 4. This scheme is suitable in cases where the stove also heats other rooms.

Fresh air is sucked in by the stove through holes in the floor and, passing through the firebox, goes into the steam room and into the washing room. It is removed from the premises through the holes located below, above the floor level.

There are also combined ventilation schemes, but for their do-it-yourself device, consultation with a specialist is necessary.

To clearly understand how ventilation is arranged in the bath, the video in this article will help you.

Baths have always been famous for their healing properties. But in order to obtain a healing effect, it is necessary not only to listen to the advice of doctors, but also to organize the correct ventilation system in your own bath.

Those who have been to the classic village baths, made of wood, are unlikely to remember the presence in such paired exhaust holes. In fact, they are not there. After all, a small amount of fresh air entering the bath from cracks in the floor, window or doorway, can provide the needs of 2-3 people.

But a bath, designed for a large capacity, and even more so brick, in without fail must be equipped with a ventilation system to fulfill the following important points:

• fresh air intake, which prevents the accumulation of carbon dioxide in the steam room and preserves the health of people in the bath;
• air circulation, which allows you to dry the room after bath procedures. This prevents the appearance of unpleasant odors in the bath, the growth of mold fungi and helps to increase the life of the building without the need to replace wood elements;
• uniform distribution of heated air in steam room baths.

Moreover, if the hood is arranged correctly, it should not lead to the following unpleasant consequences:

• to a drop in temperature in the steam room during bath procedures;
• violation of the correct stratification of air by temperature - the coolest layer should be at the bottom;
• removal from the steam room of clean air, and not saturated with carbon dioxide.

It is easy to breathe in a well-ventilated steam room, and it is pleasant to relax

How is bath ventilation

It is correct to provide for the bath ventilation system even at the construction stage, because it is at this moment that you can make the hood correctly and independently with the lowest labor and material costs. In addition, the process of making holes in the finished structure can lead to a decrease in the strength of the walls.

Air exchange in a bath is provided by means of two openings.

1. The supply opening is located at the bottom and provides fresh air to the bath.
2. The exhaust opening is located at the top on the wall opposite the supply opening. Thanks to the exhaust, the exhaust air is removed from the steam room. However, if the opening is located very close to the ceiling, then hot air is quickly removed from the room, which leads to a decrease in the temperature of the steam room.

This design allows you to adjust the direction of the air flow. At the moment when the bath is heated, all three holes are in a closed state. When people are steaming, the supply and lower exhaust openings are open. After bath procedures, all ventilation is in the open state, which allows you to dry the bath well.

Ventilation in the bath can be mechanical. In it, the air in the steam room circulates thanks to the injection equipment. In a more complex and expensive version, special devices monitor the air supply process, which, if necessary, start the ventilation system. The use of a mechanical hood allows you to place holes on any of the walls, as well as correct errors in the organization of natural ventilation.

In any case, to ensure air exchange in the bath, there are several exhaust schemes that differ from each other in the location of the holes.

Methods for ventilation in the bath

We describe some of the most popular and simple ways arrangement of ventilation in the steam room. They can be either with the use of fans, or carried out in a completely natural way.

Method 1

This is the one described above natural ventilation scheme with one inlet and two outlets. The inlet in such a system is made in the wall immediately behind the stove at a distance of 0.3 m from the floor surface.

To connect the outlets to each other, a box is used, which is made of wooden boards, a corrugated pipe about one meter long is laid in it. The holes themselves are provided with plugs that allow you to adjust the air flow, as described above. In addition to the plugs, you will also need gratings to prevent insects and rodents from entering the bath through ventilation.

This system is applicable for small baths.

Method 2

This is another simple and most common scheme for ventilating the bath space. In it, the supply hole is located behind the stove just above the floor (about 0.3 m). The hood is located at the same height, but on the opposite wall and is equipped with a fan that forcibly draws out the exhaust air.

Method 3

Method 3 is somewhat similar to the previous one. Only the air inlet is arranged at a height of half a meter from the heater, and the outlet is just above the floor (about 0.2 m). The hood is equipped with a fan.

Method 4

Method 4 is used for baths in which the steam room has only one wall facing the street. In this system, air inlet and outlet openings are located on the same wall opposite the stove. Air enters into the lower hole, located at a height of 30 cm from the floor, and exits into the upper one, which is located 30 cm below the ceiling and is equipped with a fan.

Clean air enters the room, collides with the stove, heats up, rises and is directed through the outlet to the outside.

Method 5

Method 5 is suitable for baths in which there are small gaps of half a centimeter between the floor boards. The inlet is located behind the stove. The cooled and exhausted air descends to the floor and exits through cracks in the underground, where there is an exhaust hole in the basement wall, connected to a ventilation pipe that discharges air flows above the roof.

Method 6

If in your steam room the stove is heated for the entire period of the bath, then the blower can itself perform the function of ventilation, or rather, the hood. In this case, only an air inlet is needed, which is located near the floor opposite the stove. The blower should be slightly lower than the finished floor.

Step-by-step instructions for installing ventilation

When arranging a bath with ventilation, it is important to observe the following conditions:

• if the bath is adjacent to a residential building, then the air flow should go in the direction from the housing to the steam room;
• the exhaust hole is connected to a box or pipe, which is necessarily brought out above the roof of the bath;
• the hood should not be done over the shelves in order to exclude the effects of a draft on steamed people.

In general, the ventilation installation process can be described as follows.

Step 1

In selected places, at the construction stage, or prepare after construction, inlet and outlet openings, the cross section of which should be 10-20 cm.

Step 2

Prepared holes are equipped with boxes made of metal, plastic or wood.

Step 3

Install an exhaust fan if necessary.

Note! For baths, it is necessary to use ventilation equipment made of heat-resistant material and with a protection class of at least IP-44.

Step 4

Mounted on grille holes and plugs.

Step 5

The outlet is connected to a pipe that is led out above the roof.

Note! In addition to ventilation of the room, it is necessary to ensure air circulation under the floor. To do this, at the construction stage, holes are made in the basement on opposite sides, which are covered with gratings to protect against rodents.

In such simple ways, you can arrange bath ventilation, ensuring a long service life of the steam room and a comfortable stay in it.

Video - Ventilation scheme in the bath

A high-quality ventilation system is an indispensable element of the steam room. The absence or improper organization of ventilation in the bath is dangerous to human health. A properly equipped system will protect people from carbon monoxide and improve the comfort of staying indoors. We will talk about the features and technology of installing the ventilation system in the bath later.

Characteristics of proper ventilation for the steam room

Proper ventilation in the bath performs several functions at once:

• provides the room with oxygen;
• improves the comfort of staying in the steam room;
• removes carbon monoxide;
• allows economically expedient to spend firewood;
• evenly distributes air flow;
• protects the building from the formation of mold or fungus.

by the most best option ohm ventilation in the bath is a supply and exhaust. For these purposes, equip:

• air inlet - through them an influx of fresh air into the steam room is organized, a fan with a ventilation tube is installed, additional air inflow is provided by open windows or through the door;
• exhaust hole - the removal of heated air from the room, through the furnace, blower or devices that improve traction.

For improvement supply and exhaust system ventilation use various ways. We offer you to get acquainted with one of the most effective ventilation systems:

1. The supply openings are located at the bottom of the room, next to the firebox.

2. Exhaust openings strictly on the opposite side from above. It is possible to organize two holes at once for better air control.

3. The height of the exhaust port determines the draft level. If the vent is low, additionally reinforce the system with a vent pipe.

4. With the help of special dampers, the air supply from the room is controlled.

5. The air in the steam room is renewed every 2-3 hours.

In addition, the individual parameters of the ventilation system are determined by the type of room, the version of the bath. For example, in a Russian bath, periodic ventilation will help renew the air. In addition, the size and location of the furnace installation are taken into account; in relation to this parameter, two types of ventilation are organized.

How to make ventilation in a steam room with a separate firebox

We offer a variant of the organization of ventilation in the steam room, the firebox of which is located in the next room. This scheme is popular in ordinary Russian baths. To bring the firebox to an adjacent room, a furnace tunnel is used. Among the advantages of this arrangement of the furnace, we note:

• lack of garbage in the steam room;
• the door to the room opens only at the entrance;
• the possibility of mounting heat-resistant glass for admiring an open flame.

There are two ways to install air inlets in a room:

1. Arrangement of a ventilation duct in the underground space. Removing it in front of the furnace room, installing ventilation grilles on the channel.

2. Floor supply of ventilation.

On the opposite wall, install the hood, diagonally in relation to the air inlet.

The main quality of the organization of proper ventilation is that the supply openings in area should coincide with the exhaust ones.

Ventilation scheme in a steam room with a firebox indoors

If the stove-heater is located directly in the steam room, then the organization of ventilation is different. In this case, air flows through the blower solve the problem with natural ventilation. This method appropriate if the fire in the furnace is constantly.

If there is no chimney in the bath, and the stove operates in a short-term mode, a more advanced ventilation system is used. Familiarize yourself with the technology of arranging the ventilation system in the steam room:

1. Build a special brick podium on which the oven is installed. With its help, a ventilation duct is supplied to the furnace.

2. Lay the ends, build another box of bricks. As a result, the first structure is installed at the top of the furnace channel, and the second - to the door of the steam room.

3. On a wall adjacent to a regular room, build doors in the places where the masonry passes. They warm up adjoining room, if necessary.

4. An oven is installed on the podium, it can be mounted on a corner or on steel paintings. Finish the furnace with brick, install a brick screen, with two convection valves.

5. The exhaust ventilation system operates due to the furnace furnace.

Correct installation of the ventilation system is based on its correct adjustment. General rules ventilation system control:

• at the beginning of the furnace furnace, all openings and supply and exhaust are closed;
• wait for the temperature to rise, then adjust the vents with valves;
• if it is necessary to increase the volume of oxygen in the room, open the inlet;
• upon completion of work, open the shutters for better ventilation of the steam room.

Steam room ventilation photo:

To determine the temperature and humidity in the room, use special devices. An alcohol or electric type thermometer will help measure the temperature. Please note that the use of the mercury version is strictly prohibited. Use a hygrometer to determine the humidity level.

The principle of operation of the ventilation system is based on the following factors:

• melting the oven, the air is gradually heated and exits through the convection door;
• the lower door remains open until the oven is fully heated;
• close the door from below and work with the top hatch;
• in the process of soaring, only the blower installed on the box opens;
• after using the steam room for its intended purpose, ventilate the room well.

Do-it-yourself ventilation device in the steam room

The main functions of the ventilation system in the bath:

• air supply during bath procedures;
• high-quality room drying.

The ventilation system in the bath should not:

• violate the temperature of the room, in the process of taking bath procedures;
• to separate temperature flows, that is, cool air is closer to the floor, and warm air is from above;
• remove unused air from the steam room.

In addition, lack of ventilation leads to bad air indoors, the formation of mold and fungus, harmful to human health.

There are three main types of ventilation in the steam room:

• the natural option is the supply of air flows through the pressure difference;
• mechanical option - air supply using special mechanisms, when measuring these characteristics with instruments;
• combined option - the creation of artificial pressure by fans and hoods.

There are two types of air transport in the room: supply and exhaust. For these purposes, a hole located diagonally with respect to the inlet is equipped.

It is not recommended to install an exhaust outlet in the steam room on the ceiling, this ventilation system increases the warm-up time of the room. It is rational to install the hood under the ceiling, additionally equipping a damper on it to adjust the draft.

In addition, provide a ventilated floor in the bath. Thus, the period increases floor covering because it is in constant contact with water. Recommendations for the arrangement of floor ventilation:

1. During the installation of the foundation base, ensure the ventilation of the floors, build vents from the basement.

2. On opposite walls, build ventilation holes that provide air flow. Install gratings on them to prevent rodents from entering.

3. The finished floor should be slightly higher in level than the blower is located. Thus, it will function as a hood.

4. Install wooden planks with a small gap, at least half a centimeter.

5. After taking bath procedures, ventilate the room well and dry the floors.

Another way to organize the ventilation system in the bath is “According to Bast”. In this case, fresh air enters the room from the ward space, and exhaust from the hole located near the door. For these purposes, build an exhaust box made of wood, lined with foil inside.

Build a ventilation duct under the floor, next to a metal sheet that prevents heat from entering it. The size of the structure should not exceed twenty percent. Adjusting the flow of fresh air through such a system is quite simple. It is enough to open the vent and blower. In addition, it is possible to avoid the accumulation of an unpleasant aroma in the steam room. This method of organizing ventilation is appropriate if the firebox is located directly in the steam room.

Ways to organize ventilation in the steam room with your own hands

Install the inlet under the stove 50 cm from the floor, and the outlet on the opposite side, thirty centimeters from the ceiling. The forced movement of air masses is provided by a fan. Thus, it is possible to ensure uniform heating of the air. The height of the first opening regulates the draft force of natural ventilation.

Two ventilation holes are located on the same wall, always opposite the stove. The inlet is installed at a distance of thirty centimeters from the floor, and the outlet is thirty centimeters from the ceiling. Install a fan in the outlet, the cooled air, entering the room, collides with the stove, heats up and exits.

Position the inlet behind the stove, at a distance of about twenty centimeters from the floor. The inlet is installed at the same height, only near the ceiling of the opposite wall. A hood is installed in the second hole. The principle of operation of the system is based on the ingress of cooled air into the steam room, passing through the oven and pulling out the second hole.

This method is relevant for a steam room with a floor that has holes for water to drain. The inlet is installed behind the furnace, and the outlet is a drain pipe through which air is vented to the outside.

Relevant for a bath with a constantly working stove. The inlet is arranged opposite the stove, and the blower with a chimney acts as an outlet

If it is necessary to increase the temperature in the steam room, it is enough to close all the plugs. After taking bath procedures, they are removed. It is quite possible to organize these ventilation schemes on your own, without buying expensive appliances and special material investments.

How to make a vapor barrier for a steam room with your own hands

Vapor barrier in the steam room allows you to maintain optimum temperature premises. Special materials in the form of vapor-tight films, insulation and waterproofing will help create high-quality vapor barrier. The film provides protection of the insulation from the penetration of water vapor, while not letting in the moisture that is in the hot air.

Qualitatively equipped vapor barrier and ventilation system increase the service life of the room itself and its exterior finish. Since hot air rises, first of all, vapor barrier the ceiling with high quality.

For these purposes, use lahi, boards, about 6 cm thick. From above, they are covered with aluminum-based foil, cardboard with increased density or waxed paper soaked in drying oil. After fixing one of these materials, the ceiling is finished with clay and insulated.

In addition, the edged board will help to vaporize the ceiling. On the boards, cardboard impregnated with drying oil is installed, which is then sheathed with wooden clapboard.

Expanded polystyrene boards are a modern replacement for soft clay, they are distinguished by good thermal insulation and performance characteristics.

As vapor barrier materials for the walls of the steam room use:

Glassine and roofing material for thermal insulation of the steam room are rarely used. This is due to the fact that with strong heating, they emit toxic substances and unpleasant odors. The steam room is vapor-proofed with special foil materials. Allocate combined methods of vapor and thermal insulation. For example, NPP polypropylene, among its advantages we note:

• excellent resistance to moisture;
• resistance to temperature increase;
• laminated coating prevents the development of mold and mildew;
• combined thermal insulation.

In addition, it is possible to use rolled vapor barrier in the form of rolled foil or fiberglass boards. To seal the joints between vapor barrier materials, use foil tape.

The plates are installed on the ceiling with a small compensation gap of 20 mm. Thus, the effect of moisture on these areas is reduced. Please note that the vapor barrier in the steam room must be securely hidden behind the main finishing material, and a high-quality ventilation system is its complement.

Do-it-yourself ventilation in the steam room

Do-it-yourself ventilation in the bath: how to do it right

Why do you need to attend to the question of how to properly ventilate the bath? Not only maintaining a comfortable temperature in the dressing room, washing room, steam room, rest room, but also safety, as well as the service life of the building and its parts, depends on how well the ventilation in the bath is arranged. When designing a bath and starting its construction, it should be remembered that the ventilation in the bath with your own hands must be done taking into account certain subtleties and nuances. With your own hands, with the help of instructions, photos and videos, all stages of ventilation installation in the bath and steam room can be performed.

Properly arranged ventilation in the bath will provide comfortable temperature inside the steam room and extend the life of wooden elements

The principle of operation of the ventilation system in the bath

The operation of the ventilation system is based on well-known physical laws, and the scheme of its device is simple and understandable. Two types of openings are required for continuous air circulation:

Air inlets are needed to bring fresh air into the room. With the correct ventilation device in the bath, they should be located as close as possible to the floor and near the stove. With this arrangement, the incoming air heats up quickly and the temperature in the bath is stably maintained.

The direction of movement of air masses inside the steam room

Exhaust openings are designed to remove superheated humidified air and carbon monoxide from the steam room. They should be arranged as high as possible, that is, just below the level of the ceiling, and be located opposite the air inlets in order to create and maintain a constant air exchange.

Advice! An exhaust hole in the ceiling will lead to rapid cooling of the room, so this location is undesirable.

There are no difficulties with the fundamental localization of supply and exhaust openings when installing ventilation in a bathhouse with your own hands. But the task of maintaining a high temperature in the steam room while effectively removing exhaust air and carbon monoxide from it is not easy.

You also need to pay attention to maintaining a temperature that is comfortable for both sanitary and hygienic procedures and for relaxation, in all parts of the bath: dressing room, washing room, relaxation room. And if you have to create and implement a ventilation scheme in the bath with your own hands, you should think about the competent execution of work.

Scheme of proper air circulation in the bath

Types of ventilation

There are two types of ventilation:

Which one to choose when installing a ventilation system with your own hands depends on the design of the bath and the volume of its premises.

Ventilation system with electronic control unit

natural ventilation

This type of ventilation works due to the difference in temperature and pressure inside and outside the room. The efficiency of its work depends on the location of the openings for the inflow and outlet of air. The most suitable solution is that the supply openings are located near the floor, at a height of 250-350 mm, next to the stove, and the exhaust openings are on the opposite wall, 150-200 mm below the ceiling level.

The best photos of finishing the bath inside and a description of the stages of work. Sequence of actions when repairing a sauna. Recommended materials and installation rules for use. Waterproofing and wall insulation.

Natural ventilation systems are not suitable for ventilating a steam room or steam room, since the cold air in this room collects at the very floor, and the hot air in the upper part. Adjusting the movement of air flows is accompanied by difficulties, but with the correct arrangement of the ventilation elements in the steam room of a Russian bath, it is possible to cope with this problem with your own hands.

Natural ventilation is not suitable for a steam room, it is advisable to equip it in a rest room

Forced ventilation

For this type of ventilation in the steam room of a Russian bath or sauna, two subspecies can be distinguished:

1. Ventilation with special electronic systems which carry out control of temperature and humidity of air, by means of automatic control of its receipt and a filtration. Such systems are quite expensive, and their use is often knocked out of the budget.
2. Combined ventilation system, when due to the use of fans, the effect of natural ventilation is obtained.

The location of the ventilation ducts inside the walls of the bath

Dependence of the bath ventilation system on the type of building

Natural ventilation, provided that the vents are correctly positioned and their sizes correspond to the volumes of the premises, functions well in a Russian bath, assembled from a log or a beam.

The frame building is a sealed structure. It is advisable to use forced ventilation in frame baths. Inlet hole in outer wall steam rooms should be additionally equipped with a blower fan.

In a brick or foam block building, only forced ventilation is possible.

The type of ventilation system is selected depending on the materials from which the bath is built.

Planning the ventilation system of the bath: subtleties and nuances

Before proceeding with the choice of the ventilation scheme in the bath and the device of its design with your own hands, you need to understand the intricacies and nuances of design.

Fact! Even small errors in the layout of the supply and exhaust openings lead to undesirable consequences. In the steam room, either the constant air temperature will decrease, or the concentration of carbon monoxide will increase.

When building any bath - the ventilation of the bath and its circuit diagram laid down during construction. The question "how to make ventilation in the bath" should be decided at the design stage.

The ventilation ducts of the dressing room, washing room, steam room, rest rooms and openings for the inflow of fresh air and the removal of a mixture of carbon monoxide with exhausted moist and hot air masses must be laid at the appropriate stages of construction. Valves and gratings to control the size of supply and exhaust openings and sections of ventilation ducts are already installed at the stage finishing premises.

The planning of the ventilation system must be carried out at the stage of development of the design project of the bath room

Basically, the functioning of the ventilation of the bath depends on two factors:

• the dimensions of the ventilation openings - both supply and exhaust - which are determined by the volume of the room, whether it is a dressing room, a washing room, a steam room or a rest room;
• position of ventilation holes.

Vent sizes

The dimensions of the ventilation openings depend on the volume of a particular room: dressing room, steam room, washing room or rest room. very important as exact calculation the size of these openings, as well as providing the ability to change it. To adjust the gaps in the openings, doors-latches and gratings are installed.

Air vent with slider for adjusting the amount of fresh air inflow

It should be noted that with large ventilation windows it will be difficult to heat the room to the correct temperature. There will either be a danger of a constant waste of fuel and electricity, or difficulties in adjusting the cross section of the ventilation ducts, that is, the distance at which each opening will need to be opened with one's own hands.

Advice! The area of ​​the ventilation opening is determined at the rate of 24 cm² per 1 m³ of the volume of the ventilated room. For a good draft of fresh air from the outside, the exhaust opening must be larger than the inlet.

If the area of ​​the ventilation openings is insufficient, the temperature, air humidity and concentration of carbon monoxide in the room can rise to critical values.

The optimal size of the ventilation opening is calculated at the rate of 24 sq. cm per 1 cubic meter of room volume

The position of the ventilation openings

The action of any ventilation system is based on the replacement of masses of heated air set in motion under the pressure of air coming from outside - colder and heavier. It is important to be able to regulate the direction of the heat flow coming from the stove installed in the bath. The ventilation in the steam room is often equipped with not one inlet, but two for this very reason. To localize heat flows, it is enough to create a gap of a certain width in one or both of them with the help of valves.

Scheme of placement inside the steam room of ventilation openings for the inflow of fresh and removal of polluted air

Ventilation in the Russian bath

The quality of the ventilation system of the bath, designed and assembled by oneself, is laid down at the project stage.

The air currents circulating in the rooms will have different temperatures, but the discomfort from this should be felt as little as possible.

Advice! Comfort in the bath depends not only on the absence of sudden temperature changes "horizontally", that is, when moving from one room to another: from the rest room to the dressing room or from the steam room to the washing room. A soft movement of air masses vertically is necessary: ​​the air temperature near the floor should not be much lower than the temperature at the level of an average human height.

The microclimate in the bath directly depends on the number of ventilation holes, their size and location.

The uniformity of the intake, mixing and removal of air masses depends on the number of supply and exhaust openings, their size, location relative to each other and heating appliances, as well as equipment with additional control devices.

The main schemes of the ventilation device in the bath

Any sauna ventilation scheme is designed with one goal in mind - maintaining the temperature, humidity and freshness of the air in the steam room. The premises of the bath, and especially the steam room, are exposed to water and steam, so they need periodic ventilation and drying. But airing and drying will be ineffective if proper ventilation is not organized in the bath. Proper and constant ventilation of the steam bath significantly reduces the effects of wood absorbing moisture.

The main task of the ventilation of the bath is to maintain the temperature, humidity and freshness of the air in the steam room.

Bath floor ventilation

Air exchange in bath rooms is facilitated by a ventilated floor.

A wooden floor with constant contact with water loses its usefulness after 5 years. Requirements for ventilation through the floor:

• to create a flow, make small vents in the foundation of the bath;
• lay the floor, leaving gaps between the boards up to 1 cm;
• lay inlet openings in parallel walls (not forgetting to protect them with gratings from rodents);
• in order for the stove to work as an additional hood, lay the finishing floor above the level of the blower;
• after using the bath, leave the doors open until the floor in the room is dry.

Scheme of arrangement of the ventilation system in the sauna

Ventilation in the dressing room of the bath

With your own hands, in the presence of photo and video instructions, ventilation in the rest room of the bath and in the dressing room is the easiest to do, since they do not have direct contact with water. A natural or combined type of ventilation is used, when fresh air enters through the supply duct and is removed by a fan through the exhaust duct of the steam room, vestibule or bathroom. It is also possible to install ventilators, for which you will need a direct outlet to the street and a power supply connection.

In the dressing room, you can equip a natural or combined type of ventilation

Ventilation in the washing bath

For air exchange in the washing room, a forced ventilation system is often made, which is driven by an electric motor. Air flows lead towards the vestibule. The supply and exhaust channels are made of the same section, the input of the first is set above the ground level (by 2 m), and the output of the second is above the roof.

Ventilation in the steam room

The requirements for the microclimate of the steam room are special. It should warm up quickly, it should maintain an optimal level of humidity and be free from drafts. Therefore, for the steam room, the correct position and dimensions of the supply and exhaust channels, which are laid during construction, are relevant. To regulate the inflow and outflow of air, valves in the vents are sufficient, but with a large volume of the room, a supply or exhaust fan may be needed.

Scheme of arrangement of ventilation in the steam room

The above general principles designing ventilation in a bath, videos and photos attached to instructions from network or other resources should help those who want to build a bath with their own hands to bring this desire to a concrete embodiment.

Do-it-yourself ventilation in the bath: how to do it right

Do-it-yourself ventilation in the bath

In the process of arranging the bath Special attention need to pay attention to the organization of high-quality ventilation. Without proper air exchange, the steam room simply cannot be used normally. If desired, all work on the installation of the necessary systems can be done by hand. It is enough just to figure out the order of laying and connecting the main units and do everything in accordance with the instructions.

Why do you need ventilation in the bath?

Why do you need ventilation in the bath

Bath ventilation is very important. To avoid lengthy and not very interesting explanations, you can consider everything with a specific example.

The visitor to the bath stays in a room filled with a large amount of hot steam. The person inhales this vapor. We know that humans breathe in oxygen and exhale carbon dioxide. In the absence of sufficient air exchange, after a while a person will simply burn out.

That is why the ventilation in the bath should be as efficient as possible and made in full accordance with the technology. There are several types of ventilation systems. Explore the features of each option and choose the method that best suits your case.

Steam room ventilation

Ventilation systems are installed to solve two main tasks, namely:

• ensuring the supply of clean air to the bath;
• removal of exhaust air from the steam room.

Additionally, ventilation provides faster and better drying of the steam room. It is necessary to study the features of existing ventilation systems and understand the order of their installation in order to obtain the most efficient and high-quality air exchange.

It is important that during the operation of the ventilation system the characteristic of the bath is not disturbed. temperature regime. Air exchange should be organized in such a way that there are no disturbances in the distribution of temperature flows in the bath. Cool air in the steam room can only be near the floor. And the higher the ceiling, the higher the air temperature should be.

Ventilation should not take away from the bath fresh air. A properly equipped system supplies fresh air to the room and removes the exhaust air. Errors in the installation of the system will lead to extremely adverse consequences for both the bath and its visitors.

Mold damage to wood

The main types of ventilation systems

There are several types of air exchange systems suitable for use in a bath, namely:

• natural ventilation. The principle of operation of such a system is based on the use of the pressure difference inside the bath and on the street. The simplest and most inefficient option;

Exhaust fan from the steam room

Exhaust air is removed from the bath through a special ventilation duct. The air exchange installation technology requires that the duct be installed diagonally to the inlet through which fresh air enters the bath.

Take care of the ventilation device in all areas of the bath, and not just in the steam room. The dressing room, rest room and other rooms of the bath should also be well ventilated.

What you need to know about floor ventilation?

Quite often, the owners of the baths forget that the floor of the steam room must also be well ventilated. Such forgetfulness leads to a very rapid deterioration of the structural elements of the floor and, in general, a deterioration in the characteristics of the bath.

Floors are constantly in contact with water. Without properly organized air exchange, the floor will collapse very quickly, and the floor covering will have to be changed after 2-3 years.

You need to think about floor ventilation even at the stage of bath construction, because. in already finished premises creating high-quality air exchange will be much more difficult.

First step. Make small vents in opposite walls of the basement. It is best to provide for these vents at the stage of construction of the concrete base of the bath. Creating any holes in an already finished structure will lead to some decrease in the strength of the building.

Ventilation in the steam room

Second phase. Make one ventilation hole in opposite walls of the serviced room. Through them, clean air will flow into the room. Holes must be through. Ready channels are recommended to be closed with special ventilation grilles. Such protection will not allow to penetrate into the bath different kind rodents and other pests.

Ventilation in the bath

Third stage. When building a furnace, make sure that its blower is slightly below the level of the finished floor. Thanks to this placement, the oven will also start working in the hood mode.

Fourth stage. Lay floor boards. When laying them, you need to leave gaps about 7-10 mm wide. Through these cracks, water can flow down. If the liquid lingers on the floor every time, the boards will rot very quickly.

Quite often, floor ventilation is arranged “according to Bast”. According to this technology, fresh air comes from under the stove, and exhaust oxygen is removed through a hole under the ceiling.

In accordance with the requirements of fire safety, a metal sheet must lie near the sauna stove. It is near this sheet that a hole is created to supply fresh air to the bath.

For the device of such air exchange, a special exhaust duct is required. You can buy a box ready-made or assemble it yourself from boards. The inner surface of the exhaust box must be covered with foil. The size of the box should be approximately 15-20% larger than the diameter of the chimney.

Ventilation "according to Bast" is the best option for those cases when the stove is located directly in the steam room. In such a situation, ventilation ducts can be equipped even directly in a brick podium.

Pay attention to the installation location of the sauna stove. If the stove is located directly in the steam room, then natural air exchange is present initially. You just don’t need to rely solely on it - such ventilation only works when the stove is running.

The most optimal option for installing ventilation is the arrangement of air exchange channels on opposite walls of the bath. They must be at different heights.

It is not recommended to place the ventilation holes too high. Although in most other cases it is recommended to make an exhaust hole directly under the ceiling, slightly different rules apply in baths. If you place the hood directly under the ceiling, hot air will leave the room very quickly.

For baths, the optimal height for placing ventilation holes is a level equal to 1-1.5 m.

Bath ventilation installation guide

There are several simple ways to organize effective air exchange in the bath. Study each of them and choose the best one for your steam room.

First way. Create an opening for fresh air. It should be behind the stove, about half a meter from the floor. Make a hole for exhaust air from the side opposite to the inlet, at a height of about 30 cm from the floor level. Install a fan in the outlet.

Create an opening for fresh air

The lower you place the exhaust duct, the more intense the air exchange will be.

However, there is no need to be too zealous either. Try to make holes at the recommended height, as such values ​​are the most optimal. Openings are recommended to be closed with ventilation grilles.

The second way. With this air exchange, both vents will be on the same wall. Work will be carried out with a wall parallel to the stove. The inlet duct is created at a level of about 30 cm from the floor, the exhaust duct is at the same distance from the ceiling of the bath. The exhaust opening is equipped with a fan. Close open channels with ventilation grilles.

The third way. Make a hole behind the sauna stove for air to enter. Position the intake duct about 20 cm from the floor surface. The exhaust channel is made at approximately the same height, but in the opposite wall. The exhaust opening is equipped with a fan. Close open channels with ventilation grilles.

Fourth way. This air exchange option is great for baths, the flooring of which is laid with slots to drain water. Make an inlet behind the stove unit at a distance of about 30 cm from the floor surface. An exhaust hole is not made in the case of such ventilation - the exhaust air will leave the bath through the cracks in the floor covering, and only after that it will be discharged to the street through a common ventilation pipe.

Ventilated floors in the bath

Fifth way. Such ventilation is ideal for baths with a constantly working furnace unit. Install the inlet channel opposite the stove, stepping back about 30 cm from the floor. The function of the hood will be performed by the oven.

Thus, the procedure for arranging ventilation is practically the same in all the considered methods. Each of them involves the creation of one or two holes, only the place and height of their placement change.

You can also make the holes yourself. brick walls are easily passed with a puncher, and log ones with any tool suitable for this, for example, with a wood drill. It is recommended to invest in finished holes plastic pipes. Don't forget about protective ventilation grilles. In the future, you are unlikely to be happy with uninvited guests in the form of rodents.
