The height of the kitchen hood above the gas stove. Calculation of the distance from the stove to the hood
The ventilation ducts that are located in the building do not always cope with the problem of exhaust air. Often, they are ineffective. The way out of the situation could be exhaust system.
Starting installation, the question arises, what should be the distance from the stove to the hood and what kind of hood should I hang in my kitchen? This question is very relevant. The quality of its work and the degree of air purification depend on the height at which the kitchen hood is installed.
The design is designed to remove dirty air, fumes, soot, odors, gas combustion residues and other harmful components outside the building or clean the air with its subsequent return to the kitchen. The level of cleaning the room from dirty air depends on the height at which the hood is hung and how the air will be cleaned.
Depending on where the intake air goes, the method of cleaning it is determined. It can be flow or circulating. Which exhaust system to pay attention to depends on the conditions of the kitchen equipment and the presence of ventilation shafts in the building.
The flow-through method of cleaning consists in drawing in dirty air and removing it through the ventilation system of the building outside of it. positive side This method is the maximum and quick cleaning of the kitchen from harmful air. To receive fresh air enough to open a window or window.
The circulation method is based on the suction and pumping of dirty air through a system of carbon filters, with its subsequent withdrawal into the kitchen. This method does not require ventilation ducts. A significant disadvantage is the long time for air purification and the rapid wear of the filters.
Varieties of exhaust devices
Depending on the location of the stove, the design of the kitchen hood and the method of its installation are selected. Exhaust systems for the kitchen are divided into the following types:
- Suspended. They have a flat shape. The place of installation can be the bottom of a wall cabinet or shelf.
- Embedded. This type is mounted instead of the bottom of the wall cabinet. Often the cabinet itself serves as a housing that hides the exhaust system and its communications.
- Wall. Installation is carried out above the stove, like a suspended exhaust system. But the mounting of the system case is carried out on the wall.
- Corner. Installation of such devices is carried out above the stoves, which are located in the corner of the kitchen. They have an angular shape.
- Island. Used in large kitchens. Mounted on the ceiling in the center of the kitchen.
How to find out the distance to the hood?
The hood is a very useful kitchen appliance, relevant not only for large kitchen areas of restaurants and cafes. Compact versions of these air fresheners are also in high demand among ordinary consumers. Moreover, they do not require any special skills to install. However, if you deviate from the instructions or make a number of, even if not the most gross, errors during installation, then the performance of the device will be in jeopardy. One of important issues, which is often encountered during installation - how to correctly calculate the distance from the stove to the hood.
One of the key installation issues is the direct installation height of the hood above gas stove. That is, we must calculate the distance from the hob to the hood so that it qualitatively absorbs all possible fumes, but at the same time does not damage the cooked products. The most dangerous option, in case of an error, would be to install the hood below the norm. The grease filter under the pressure of temperatures from the stove has a risk of simply catching fire. But this does not mean that the hood should be installed as high as possible. In this case, balance and optimal calculation are needed.
If the distance from the stove to the hood is too large, it simply will not be able to absorb a large part of the fumes that are harmful to us.
Nowadays, a huge number of various types of hoods are presented, and each of them has different moments in the installation. Let's consider the main ones.
Classification of kitchen hoods
Now the market household appliances incredibly extensive. This also applies to extracts. There are a huge number of these devices, the main ones are divided into:
- Embedded.
- Fireplace type.
- Filtering.
- Air intake.
Chimney type exhaust device
There are several other options, but they are less common or not as popular.
Now consider the main rules for installing the hood over the stove, determine the distance and dimensions.
First of all, the dimensions of the hood should not exceed the dimensions hob.
The appliance must be hung strictly symmetrically from the hob, otherwise there will be a risk that it simply cannot cover all the fumes emitted during cooking.
Important Installation Points
AT different occasions the distance between the hood and the stove can vary significantly. However, each case has its own standard. If we consider such a case as installing a hood over a gas stove, then the distance should vary from 55 to 65 cm - for an inclined type.
If the appliance is of the direct type, then the height of the hood above the gas stove should be from 70 cm to 80 cm.
The installation of a hood for a gas stove should be approached with more caution, since here you need to think about the issue of fire safety, which cannot be said about the electric version.
For electric ovens, the same principle works, but with a different distance - from 35 to 45 cm for an inclined type and from 60 to 65 cm for a straight one.
The distance between the electric stove and the inclined hood.
When calculating the distance, the reliance is mainly on three factors - the power of the hood, the configuration of the room and the height of the owner or hostess who will cook in the kitchen. If all factors are met, then the appliance installed above the stove will perform its functions properly, without disturbing the owners of the kitchen at all. The given distance figures are minimal and it is already impossible to reduce the distance in any case. However, in certain cases, this figure can be increased if the functionality does not suffer. However, calculating the distance is not a difficult task, in most cases the recommended figures are indicated in centimeters in the instructions that came with the unit.
If you use the services of a master, then the issue of the installation height of the hood will not be relevant at all, he will be able to most optimally determine the position based on own experience, as well as install the entire supporting system - sockets and air ducts.
Installation tricks
Let's move on to the main question - how to hang the hood? Measurement must be made from the burners on the stove to the lowest edge of the hood. You should be especially careful when approaching the fastening process, since subsequently it will not be possible to correct the mistakes made at this stage. When calculating the distance, it is important to consider it not only relative to the plate, but also pay attention to the totality of all other factors of the exhaust system. It is necessary to work out the issue of access to power, as well as the possibility of installing a high-quality air duct.
Installation rules
Particular attention should be paid to the specifics of the installation, when it comes to different types extraction equipment. The fireplace hood is attached to the wall, and the built-in hood is installed in a specially installed hanging cabinet. corner option located in the corner of the kitchen area.
Important conditions for calculating the height during installation are the usual household factors - the number of family members, how often the stove is used for cooking and how long you will be in the kitchen room.
Conclusion
Thus, we see that the installation of the hood is not the most difficult task. However, it requires the most accurate calculation and painstaking responsible approach, as well as knowledge of all the rules for interacting with various kitchen appliances.
Considering domestic factors, you can choose the most suitable option for you, clearly calculate the distance and make a high-quality installation. Good luck and easy work!
During cooking on the stove, fumes rise from the surface of the dishes, containing fat, combustion products and other harmful substances that must be removed. These purposes are served by a household kitchen hood, which is mounted directly above the hob. It, in addition to smoke and excess moisture, also removes odors, including unpleasant ones, that form during cooking. The exhaust device provides direct air exchange in the kitchen room, pushing the captured air volume, previously passed through the filter set, directly outside the room or into the general ventilation system. The key issue when installing an air intake device is to determine the correct suspension height above the slab.
At what distance from the stove should the hood be installed
Why is the distance from the hood to the stove so significant? The fact is that with a correctly selected height, the device will work most efficiently, in acceptable temperature conditions and will be able to last as long as possible.
REFERENCE! If the appliance is hung too low and interferes with access to kitchen utensils, cooking will not be comfortable.
Norms of distance from the stove to the hood
There are two main configurations of hoods, the requirements for mounting height, to which they differ: horizontal and inclined. Let's consider each of the options separately.
The horizontal hood is located parallel to the plane of the hob. For electric, including induction models, the suspension distance should be within 65–75 cm.
If we talk about gas stoves, then due to the presence of open flames in the burners, the requirements for the installation height of exhaust equipment are more stringent. The distance to the filter layer should be in the range of 75 - 85 cm.
Inclined models are mounted under obtuse angle to the plane of the plate. This allows you to significantly reduce the distance from the hob to the nearest exhaust point and make the working space above the stove more convenient. However, the inclined shape of the equipment will require more power for the same quality of air purification.
The distance between the hood and the electric stove in this case is reduced to 35–50 cm, and in the case of gas burners, the suspension height is allowed within 55–65 cm.
There are several other types of hoods on the market:
- domed;
- island;
- T-shaped;
- angular.
As a rule, they differ from horizontally oriented models only in terms of decorative design and attachment features. At the same time, the requirements for the distance to the tiles remain the same.
When choosing the exact distance during installation, you must be guided by the information from the operating instructions for a particular model, as well as the features of the kitchen and the wishes of the owners. In some cases, it is necessary to place the air intake device below the recommended values, for example, due to low ceilings, or, conversely, higher.
Factors to consider when calculating the distance from the stove to the hood
What factors must be taken into account when determining the minimum distance between the plate plane and the hood? First of all, it is the type of tile. You should also consider: the size of the kitchen, the features of its layout and design, the configuration and power of the hood, the anthropometric data of the user.
REFERENCE! The power of the hood should provide ten times the air exchange of the kitchen room with a small margin. Air exchange performance is one of the main specifications these devices, on which their power depends.
Performance can be determined using the following formula:
P \u003d V * 10 * k (m3 / h),
where:
- P - performance (air exchange rate);
- V - the volume of the room, equal to the product of its length, width and height;
- K - safety factor, which takes the value of 1.3.
The dependence on the temperature of the working burners is obvious - the higher the heat, the further the lower part of the filter device should be located. An open fire increases this distance by an average of 10 cm.
The height of the stove user is also an important factor in determining the installation height of the air intake. A tall hostess is unlikely to feel comfortable if the lower part of a horizontally oriented hood is at eye level. In such a case, it makes sense to provide for a mount higher than recommended in a standard situation. The second way out for tall users is to choose an inclined type hood.
IMPORTANT! To compensate for the increased height of the suspension, it is advisable to choose a model with a higher capacity to provide the same level of air purification.
Reducing the distance to the hob less than the recommended one can only be allowed in exceptional cases: if the design features or low ceilings of the room do not allow compliance with the standards. This will inevitably lead to an increase temperature regime and reducing the service life of equipment, increasing the likelihood of its premature failure. There is also a growing risk that, during prolonged use, the lighting elements located on the lower part of the hood can often overheat and burn out.
Ultimately, a properly selected suspension height should provide.
The functional abilities of house exhaust ventilation ducts almost always left much to be desired. They could not cope with their main task - extracting exhaust air from the kitchen and unpleasant odors. That is why subsequently such useful and necessary devices as hoods were invented, which acted much more efficiently than channels. When planning to mount new kitchen equipment, many people think at what height to hang the hood? Does it matter. The height at which the device will be fixed often determines the performance and quality of its operation.
The design of a standard hood
You can more accurately represent the location of the hood if you at least understand a little about its device. The standard hood consists of the following elements:
- Steel case;
- Engine;
- Engine impeller;
- Filter;
- Control device.
You can set the modes for the operation of the hood. There are only two of them - filtration (recirculation) and air outlet to the ventilation duct.
Hood types
There are four main types of kitchen hoods:
- wall fume hoods;
- Island hoods;
- Embedded structures;
- Desktop devices.
The first type has the form of an umbrella with a pipe, which is fixed on the wall where it is clearly visible. Therefore, its design should be suitable for the interior of the kitchen. Outwardly, it is very reminiscent of a chimney from a fireplace.
Island-type devices are most often attached to the ceiling. They are used if the interior of the kitchen is thought out so that the stove is in the center of the room. This model works only in one mode, according to the principle of air removal.
Built-in appliances are placed inside cabinets. They are hidden from view, so they can not be finished too carefully. Their technical characteristics are not worse than those of other models, but they cost a little less.
Desktop structures are built into the hob itself. They look like another panel section. Due to the fact that this model is located in close proximity to the source of dirty air, the quality of cleaning is usually on top.
How to determine the height of the hood mounting
Very often, in order to determine the optimal mounting height of the hood, just look at the instructions for this device model. Usually, not a certain distance is indicated, but a range within which the exhaust equipment for the kitchen should be placed.
In this case, one should take into account such important facts as the growth of the hostess of the apartment and the features of the interior of the kitchen. But even if the instructions are lost, there is another way out. There are standards, thanks to which you can more clearly determine at what height the kitchen hood should be placed above the hob or stove.
It is necessary to take into account the type of hob, each type has its own measurements. So, at what height is it recommended to hang the hood:
- Above the gas stove it is placed at a height of 75-85 cm,
- Above electric stoves - at a height of 65-75 cm.
If you have chosen an inclined model, then the distance from its bottom to the hob should be approximately 55-65 cm for gas stoves, and about 35-45 cm for electric stoves.
The height may vary, but only within the specified 10 cm, and also depending on the power of a particular model and its technical characteristics. These restrictions should not be neglected, not only the quality of equipment operation, but also the safety of work, in particular fire safety, depends on these indicators.
Basic rules for installing the hood
More quality work device is possible only if the hood completely covers the surface of the stove. In this case, the polluted air will be almost completely absorbed, and its leakage will be minimal. This is the main reason why customers prefer models with a wider umbrella, from 60 to 90 cm. This size corresponds to the size of a standard slab or panel.
Placement Height exhaust hood determined in accordance with ergonomic rules and fire safety standards. The shorter the distance from the umbrella to the hob, the better the kitchen fumes and bad odors will be absorbed. But at the same time, the height should not be too low, otherwise the risk of damage to the ventilation system is high. This can happen due to overheating or even ignition of a greasy film that forms on the surface of the filter.
Therefore, for safety reasons, the minimum distance from the stove to the umbrella should be about 50-65 cm. The values may vary slightly. Often the optimal installation height of the hood is indicated in the data sheet. For reasons of ergonomics, it should be located so as not to interfere with cooking.
Hood mounting options
There are several mounting methods. The first involves placing exhaust device inside a hanging cabinet that lacks a bottom. An exhaust device is attached to the central shelf. In the same shelf, as well as in the ceiling of the cabinet, holes are made for the outlet of the hose.
One end of the hose is attached to the hood, and the other is pushed into the holes and led out into the ventilation duct. In filtration mode, the hose is cut off when exiting a hole in the ceiling of the cabinet.
The built-in type of hood is mounted according to the scheme, which is presented in the instructions for it. The model is designed for installation in a box or in a hanging cabinet.
Hood attached to the bottom of the cabinet
A hole is made for the hose in the bottom of the kitchen cabinet, as well as in the ceiling shelf. To vent to the ventilation, the hose is brought to the very opening of the ventilation vent.
For the filtering mode, it is cut off at the exit from the opening of the ceiling shelf of the cabinet. The hood is hidden behind the panel, the material for it is the material identical to that from which the cabinet doors are made.
Mounting the hood in a hanging cabinet
A hole is made in the bottom of the cabinet, the size of which corresponds to the size of the kitchen hood. The hood island is hidden in a locker. Fastening is carried out using holes in the bottom edge, with which the hood is screwed to the bottom of the cabinet.
In the shelf located in the middle of the cabinet, as well as in the ceiling, holes are made for the passage of a hose, one end of which is attached to the hood, and the other is pushed into the hole in the central shelf and ceiling. In the mode when the air is discharged into the ventilation vent, the hose is passed into it, and in the filtration mode, on the contrary, it is cut off near the exit from the hole.
Rules for installing a hood with an air duct
This type of installation provides a duct with a larger diameter and without bends. Air ducts should be made of foil with a greater thickness, thin foil will rustle with air movements. And PVC boxes are more flexible, their use is even more profitable. It is better if their shape is round and without bends. They have excellent sound insulation and do not resist air.
In no case do not narrow the passage for air, do not cling to adapters that will delay it. The required volume of air must pass in a certain period of time. If there are obstacles and narrow sections on the way, the hood motor will increase speed. Because of this, it wears out more, excess noise is created in the duct.
When connecting the hood to the ventilation shaft, filtering mode is used to overcome these obstacles. In order for dirty air to leave the kitchen more efficiently, there is an extreme way - this is to make a through hole in the wall above the surface of the hood.
You can beautifully decorate such a device with the help of PVC boxes. You can mask a flexible duct using such a drywall box.
Unfortunately, people do not always remember that fume hoods also need to be cleaned, so grease and dust accumulate on them. If the height when installing the hood does not reach 80 cm, then the filter may ignite from the open flame of the furnace.
In any case, for safety reasons, a household hood must be provided with good grounding. Due to constant power surges in the network, its engine or electronic control unit may burn out. Another problem is that due to heating, spontaneous activation of the exhaust equipment may occur. Most people still decide to purchase a modern hood, which is becoming one of critical devices in the kitchen, relieving space from unpleasant odors and waste.
During the operation of stoves, it is necessary to clean the atmosphere of the room from harmful products released during combustion. Therefore, the presence of an exhaust device in the kitchen is really vital. But at what distance from the stove is it required to install a kitchen hood? From this parameter depends on the efficiency of the device and ensure the cleanliness of the air surrounding the cook.
The distance between the bottom panel of the device and the hob depends entirely on two criteria - the placement of the equipment and the type of stove.
The type of the hood itself, its components, as well as the size of the air duct do not determine the required installation height, except for situations with a low ceiling, when it is simply impossible to mount the hood higher for structural reasons. The calculation should always take into account the rated power of the equipment, adding or subtracting 10 centimeters from the average design height of the installation. By the way, about other rules for installing the hood -.
Horizontal hood
Only on type cooker depends on the height of the hood, in which the plane sucking steam is located horizontally. The patterns of placement of this type of equipment depend on many parameters, the main of which are the characteristics of the device, model, type of plate:
- Above the gas burners, the device should be hung at a distance of 65-85 cm;
- Above the electric stove - 60-80 cm.
When mounting an inclined hood model, you must adhere to the following recommended heights:
- 55-65 cm when there is a gas burner at the bottom;
- 35-45 cm if food is cooked on an electric stove.
Naturally, no one forbids mounting the hood where its operation will be most convenient. However, all the recommended values are not taken from the ceiling. When calculating them, several important criteria should always be taken into account:
- kitchen area;
- Her layout;
- Interior;
- The power of the installed hood;
- Housewife growth.
If necessary, the installation height of the equipment can be easily increased, but it must not be lowered below the minimum permitted distance. Such installation will complicate the operation of the equipment - the hood will interfere with the housewife, who will soon get tired of hitting her head against it.
Important! By placing the hood too low, you predetermine its constant heating. It is better not to allow this, otherwise the equipment will quickly break down.
Mounting height above electric stove
By itself, any kitchen hood is a design that allows you to forcefully suck in polluted air, purify it with high quality, taking all kinds of fumes, incomplete combustion substances, smoke components, food odors and other suspended impurities formed above the stove during cooking.
The design of the exhaust unit significantly determines the height of the equipment location, the conditions for its installation. According to the mounting features, the following hoods are produced:
- suspension system completely flat, the device is mounted under the kitchen cabinet, directly hanging over the stove;
- Built-in type device, when the case is mounted inside a cabinet hung above the stove;
- The most common wall-mounted option - fastening is carried out on the wall adjacent to the stove;
- Equipment corner type convenient in a situation where it is convenient to place it in the corner of the kitchen, if there is a stove there;
- The island version of the device is used in spacious rooms where it is required to fix the hood in the center of the kitchen to the ceiling.
When mounting a kitchen hood over an electric stove, it is necessary to be guided by the fact that it is undesirable to place it below 60 cm from the hob. Although this parameter is not critical, since there is no risk of blowing out the flame. Therefore, the minimum distance is quite possible to vary.
At what height should a hood be installed above a gas stove?
Many years of practical experience in the practical operation of various models of hoods has led to the fact that recommendations have appeared that determine the minimum allowable height of the equipment above gas burners.
Different manufacturers in the instructions for the equipment oblige consumers to comply with certain installation conditions. For example:
- The Metida60W brand hood manufactured by Shindo has a capacity of 420 m 3 / h and should be installed at a distance of 75 cm from the burners. It is not recommended by the manufacturer to use the device if there are no dishes on the working burners that cover an open flame.
- The Bosch DWW09W650 brand hood has a declared capacity of 650 m 3 / h. It has a telescopic air intake design, it can be lowered to the stove, but not closer than 65 cm from the burner.
- The Russian installation of the Saturn M60 brand has a capacity of 245 m 3 / h. Manufacturers recommend mounting it higher than 75 cm from the burner.
In general, the distance between the burners and the bottom of the installation is determined by the following requirements:
- Eliminate the possibility of spontaneous combustion;
- Provide convenience for the housewife;
- Ensure that polluted air is drawn in completely.
However, in order to optimize the functioning of the equipment, this value must be clarified. You should certainly ensure the convenience of the housewife, so take into account her growth. In some cases, the installation height of the hood should be increased by purchasing more powerful equipment.
Installing an outlet
The practical height of the hood installation above the stove affects the location of the outlet into which the device will be connected. Most often, the outlet is installed directly above the hood body. Although a good option would be to fix the outlet a little higher (10-30 cm) from the line of hinged kitchen cabinets.
It should not be forgotten that it is necessary to shift the hole for the future outlet by 20 cm relative to the axis of symmetry of the device, since this is where the exhaust channel will be located.
The installation of the hood requires the observance of some nuances that guarantee the effective functioning of the equipment:
- The air receiver must completely cover the working surface, since only in this case it will be able to completely capture the evaporation from it.
- When purchasing and installing the hood, be sure to consider the dimensions of the niche where it is supposed to be mounted.
- Ideally, when the hood is slightly wider than the hob.
- The hood must be equipped good lighting and not make a lot of noise.
- Hoods are equipped with a short electric cord at the factories, which makes it advisable to install an outlet near the equipment.
- The air duct of the installation must certainly have a minimum of right angles - this affects the efficiency of air intake.
