The distance from the stove to the hood: what norms and factors should be taken into account during installation.

During cooking on the stove, fumes containing fat, combustion products and other harmful substances to be removed rise from the surface of the cookware. These goals are served by a household cooker hood, which is mounted directly above the hob. It, in addition to smoke and excess moisture, also removes odors, including unpleasant ones, which are formed during cooking. An exhaust device provides direct air exchange in the kitchen, pushing the trapped volume of air, previously passed through a set of filters, directly outside the premises or into the general system ventilation. The key issue when installing the air intake device is determining the correct suspension height above the stove.

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 the right height, the device will work most efficiently, in acceptable temperature conditions, and will 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.

Standards of distance from the stove to the hood

There are two main configurations of hoods, requirements for mounting height, to which they differ: horizontal and inclined. We consider each of the options separately.

The horizontal hood is parallel to the cooking surface. 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 fire in the burners, the requirements for the height of installation 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 at an obtuse angle to the plane of the plate. This allows you to significantly reduce the distance from the hob to the near point of the hood and make more convenient the working space above the stove. However, the inclined shape of the equipment will require more power with 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 more 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 mounting 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 the specific 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, above.

Factors to consider when calculating the distance from the stove to the hood

What factors should be taken into account when determining the minimum distance between the plane of the plate and the hood? First of all, this is the type of tile. It should also be taken into account: the size of the kitchen, the features of its layout and design, the configuration and power of the hood, anthropometric user data.

REFERENCE! The exhaust power should provide tenfold air exchange in the kitchen with a small margin. Air exchange performance is one of the main technical characteristics of these devices, on which their power depends.

Performance can be determined using the following formula:

P = V * 10 * k (m3 / h),

Where:
- P - productivity (air exchange rate);
- V - the volume of the room, equal to the product of its length, width and height;
- K - safety factor assuming a value of 1.3.

The temperature dependence of the cooking zones is obvious - the higher the heat, the farther the lower part of the filter device should be located. Open fire increases this distance by an average of another 10 cm.

The growth of the stove user is also an important factor affecting the determination of the mounting height of the air intake device. A mistress with a high growth is unlikely to feel comfortable if she falls at the eye level with the lower part of the horizontally oriented hood. In this case, it makes sense to provide 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 of greater power to ensure the same level of air purification.

Reducing the distance to the hob less than the recommended one can be allowed only in exceptional cases: if the design features or low ceilings of the room do not allow to comply with the standards. This will inevitably lead to an increase in temperature conditions and a reduction in the service life of equipment, an increase in the likelihood of premature failure of it. There is also a growing risk that during prolonged use, lighting elements located on the bottom of the hood can often overheat and burn out.

In the end, a correctly selected suspension height should provide:

• convenience in the process of cooking;
• safety of equipment operation;
• high-quality air purification.

Given all of the above factors, we can conclude that the safest and most functional distance from the hob to the hood lies in the range of 70–90 cm.
