Distance from stove to hood

When cooking on a stove, fumes rise from the surface of the cookware containing fat, combustion products and other harmful substances that must be removed. A household kitchen hood, which is mounted directly above the hob, serves these purposes. In addition to smoke and excess humidity, it also removes odors, including unpleasant ones, that are formed during the cooking process. The exhaust device provides direct air exchange in the kitchen, pushing the captured volume of air, previously passed through a set of filters, directly outside the room or into the general ventilation system. The key issue when installing an air intake device is determining the correct height of the suspension 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 the right height, the device will work most efficiently, within 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.

Distance standards from the stove to the hood

There are two main configurations of hoods with different mounting height requirements: 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 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 slab. 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 with the same quality of air purification.

In this case, the distance between the hood and the electric stove is reduced to 35–50 cm, and in the case of gas burners, the hanging height is allowed within 55–65 cm.

There are several other types of hoods on the market:

• dome;
• island;
• T-shaped;
• corner.

As a rule, they differ from horizontally oriented models only in terms of decorative design and mounting features. However, the requirements for the distance to the tiles remain the same.

When choosing the exact distance during installation, you must be guided by information from the operating instructions for a 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 need to be taken into account when determining the minimum distance between the plane of the slab and the hood? First of all, this is the type of tile. You should also take into account: the size of the kitchen, features of its layout and design, configuration and power of the hood, anthropometric data of the user.

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

Productivity can be determined using the following formula:

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

Where:
— P – productivity (air exchange rate);
— V is the volume of the room, equal to the product of its length, width and height;
— K – safety factor, taking the value 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 another 10 cm on average.

The height of the user of the stove is also an important factor influencing the determination of the installation height of the air intake device. A tall housewife is unlikely to feel comfortable if the lower part of a horizontally oriented hood is at eye level. 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 suspension height, it is advisable to choose a model with higher power to provide the same level of air purification.

Reducing the distance to the hob less than recommended 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 in temperature conditions and a reduction in 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 bottom of the hood may often overheat and burn out.

Ultimately, a correctly selected suspension height should ensure:

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

Taking into account all the listed 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.
