Extraction height above the stove: gas, electric, standards and norms of distance for installation

No modern kitchen is complete without an exhaust hood. These devices prevent air pollution in the house by particles of fat, combustion products and strong odors that accompany the cooking process.

When choosing an exhaust hood, many rightfully focus on the aesthetic appeal and technical characteristics of the equipment purchased. At the same time, they miss the question of the importance of properly placing the device in the kitchen.

You can choose a technically perfect model that fits perfectly into your interior. But if you make a mistake with the placement of the device, you can get a useless and non-functional design. And in some cases it will even be dangerous.

One of the most important aspects of the installation is the observance of the necessary distance between household appliances: exhaust hood, gas / electric stove or surface.

We will figure out at what distance you can hang the exhaust structure.

Types and originality of exhaust devices

Principle of operation

All products currently on the market, according to the principle of operation, can be divided into two large classes: circulation and exhaust.

Circulating

Circulation units provide filtering of kitchen air through an integrated multi-stage filter system. After that, the purified air returns to the kitchen.

They usually consist of a filter separator that traps large particles and a carbon filter that absorbs odors.

The polluted air above the stove is drawn in by the fan into the hood, passes through the filter system and is again in the room.

The efficiency and performance of such systems is small.. They are recommended to be used only in cases where it is not possible to connect the hood to the ventilation system.

Exhaust

Exhaust structures allow the removal of contaminated air from the room through the ventilation duct of the building.

In devices of this type, mechanical grease filters-mesh must be used to prevent "overgrowing" of the ventilation duct.

Before choosing a model, it is necessary to calculate the required power of the exhaust hood.

Reference. Maximum productivity should provide a twelve-time change of air in the kitchen in 1 hour.

Usually, many modern models are universal. They can work both in circulation and in exhaust mode, depending on the connection method.

Design

According to the type of design, hoods are divided into the following types.

• With a flat surface.
• Domed.
• Inclined.
• Recessed.

Devices with a flat surface

The simplest and most inexpensive type of exhaust devicecharacterized by compact size and low price.

These models able to work most effectively autonomously in a circulating modethanks to filters built in.

The disadvantages of these devices include the need for regular cleaning and replacement of filter elements. In most cases, the technique does not have an aesthetically attractive appearance. These shortcomings are partly offset by the relatively low cost of the product.

Dome

Another type of device that is widely used in our kitchens.

The main mode of operation of devices of this type is exhaust. They capture rising hot air, which is saturated with water vapor and particles of fat. And then they remove it from the room through the ventilation duct.

The effective operation of these models depends on the correct installation. In this case, she provided even in passive mode, without turning on the built-in fan.

In some models of exhaust umbrellas, it is possible to install carbon filters to ensure circulating operation with reduced efficiency.

Inclined

Inclined Devices are a type of dome exhaust.

They are considered the most aesthetically perfect and modern. These devices combine attractive appearance, excellent ergonomics of the workplace and high efficiency.

The main disadvantage of these devices is the relatively high cost.

Recessed

The main difference between these models from those listed above is that the design itself and the ducts are hidden from view in the wall cabinet.

How to choose the right place for the hood

The main requirement for the installation site of the exhaust devices is to be placed strictly vertically above the surface of the stove.

Important! The size of the product must be equal to or greater than the size of the plate.

When choosing and preparing a place for a ventilation installation, the following factors should be considered.

• Distance from the ventilation duct.
• The fan power of the device.
• The ability to connect power.

If you plan to install an exhaust type device, then from the installation site to the ventilation duct of the building there should be the possibility of installing an air duct.

The duct path should choose the shortest with the least number of turns. If this requirement is not observed, the efficiency of the device will decrease significantly.

If the location of the hob is far removed from the ventilation risers, then perhaps you should think about choosing a circulation type device.

Fan power determines the maximum distance from the surface of the plate at which the device will effectively cope with its functions

An important issue is the availability of electricity near the installation site. The most correct option is to place a separate outlet for the hood above the installation site.

Attention! Considering the metal housing of the exhaust hoods, grounding is mandatory to prevent damage by electric current.

Distance between cooking equipment and range hood

Why know the distance between devices

Properly selected distance between the stove and the hood is the key to a high-quality microclimate and the convenience of working in the kitchen.

Improper installation may shorten the life of the device.

Mounting the hood is a time-consuming process. If the unit is not installed correctly and you need to mount the device again, this can lead to disturbances in the interior of the room.

What affects the distance between devices

The installation height of the hood above the countertop determines several important points at once:

• safety of equipment operation;
• the efficiency of the ventilation system;
• ergonomics of the workspace in the kitchen.

One of the main factors affecting the efficiency of the equipment is the correct distance between the stove and the hood.

If the device is set too low, ergonomics of the workspace. You will experience discomfort while cooking. BUT particles of soot and grease deposited on the ventilation grill may ignite.

Too high installationreduced hood performance and efficiency her work. This will require the constant use of an exhaust hood at maximum power, reducing its life. At the same time, the noise level in the house and the cost of electricity increase.

How to find out regulatory requirements for distance

Currently there is no single standard regarding the optimal distance between the surface of the stove and the hood. Each device manufacturer recommends its own values ​​depending on the type and performance of the device.

When installing the hood, you should rely on the following criteria:

• volume of the room;
• type of stove (above the electric or gas will be);
• equipment performance;
• the growth of family members.

The rules prescribe strict standards regarding the lower limit of the hood installation. It depends on the type of stove, providing fire safety during equipment operation.

Upper bound Installation determines the product's performance and ease of use, therefore, is not regulated by state standards. But just this parameter is most important from the point of view of effective use of the device

Standards

Standard distance for gas stoves and surfaces

If you are the owner of a gas stove, then the distance from the hob to the lower edge of the exhaust hood cannot be less than 75 cm.

Compliance with this rule prevent fire. And exclude the possibility of extinction of the flame cooker caused by too much intake air.

Standard distance for electric cookers and panels

For electric stove owners the standard is much softer, since in these products there is no open flame.

As a result, there is a lower risk of fire and there is completely no possibility of extinction of the flame by the suction air stream.

In this case, by standard the minimum distance above the electric stove should be at least 60 cm.

Nuances of instrument designs and sizes between them

How distance is determined for combined cooking surfaces

If you are the owner of a combination hob, then when choosing a distance, you must be guided by the most stringent standard for gas stoves.

That is, leave at least 75 cm between the stove and the lower limit of the hood.

How to determine the distance for inclined panels

One of the common questions of ordinary people is: how to correctly measure the distance from the surface of the plate to the inclined model of the exhaust hood.

The answer is simple: you need to measure minimum distance from the lowest point of the exhaust hood to the surface of the stove.

For happy owners of inclined models of exhaust hoods installed above the gas panel minimum distance nIf necessary, can be reduced to 55-65 cm.

Owners of inclined exhaust hoods that are over electrical equipmentmay place the bottom edge of the product at a distance of at least 35-45 cm.

We presented the norms that you need to know to properly place the hood in the kitchen. Now you know at what height the hood should be hung.

We hope that our tips will be useful, you can easily cope with the task. And your hood will delight with clean air in the kitchen.
