Kitchen hood dimensions

In the kitchen, during and after cooking, it is necessary to ensure normal air circulation to get rid of by-products - steam, gas and food odors. For this purpose, an electric exhaust device is used, usually located above the stove or hob. Its overall dimensions are selected based on the existing requirements of SNIP, as well as from the calculation of the optimal power parameters of the device. How to choose the appropriate dimensions for a hood so that it also functions as a ventilation device is described in this article.

Requirements for kitchen exhaust systems

The main parameter that you should focus on when choosing a hood is performance, which is directly related to power. To purchase equipment that suits your taste preferences, but is too low-power, means throwing money away; this decision is fundamentally wrong. When choosing the optimal hood, we are guided by SNIP standards, which indicate the following parameters:

• productivity for an electric stove with two burners – 60 m3/hour;
• with three burners – 75 m3/hour;
• with four burners – 90 m3/hour;
• for a gas stove – 100 m3/hour.

It is worth considering that the dimensions of the hood are not directly proportional to its performance; when choosing it, you should be guided by the passport data given in the attached instructions.

The minimum performance is calculated using the following formula:

P=12*S*H

Where P is productivity in m3/hour, S is the area of ​​the room, H is its height. Coefficient 12 is introduced in accordance with the standards established by the SES.

The choice of design and size is up to the buyer, the main thing is that the device meets fire safety requirements.

Selecting the width of the hood

This parameter affects solely the appearance of the device and has little to do with its performance. Modern devices are produced in widths from 350 to 1200 mm, with dimensions of 35, 45, 50 to 120 cm in increments of 10 centimeters. The selection of dimensions is usually determined by the dimensions of the slab or other device over which it is mounted, and is tied specifically to them. In addition, they are guided not by the dimensions of the entire body, but specifically by the exhaust surface.

For the most part, the dimensions of the stoves, and therefore the hoods, depend on the size of the kitchen. So, for kitchen spaces with a square area of ​​less than 12 m2, small tiles for two burners, with a working surface of 45 cm, are suitable; for more spacious rooms, up to 18 m2, 60 cm slabs are suitable.

Device depth

This parameter is most important for dome and built-in versions of the device. For dome hoods, the optimal option is equal width and depth of the device, while for built-in hoods the depth varies depending on the retractable part. When installing devices of this type, first of all, take into account the dimensions of the wall cabinets and the distance at which they are located.

What height do you need for a kitchen hood?

The height of the device is understood from two angles - the height of the device itself and the height of installation above the stove or other device.

If we talk about geometric dimensions, then we start from how high the ventilation is located, to which the device is connected, and how high the ceilings are. If we talk about the height above the stove, the following rule and standard requirements apply:

• for an electric stove, this size must be at least 65 cm;
• for a gas stove – 75 cm;
• for devices with variable tilt in the horizontal plane – 55 cm.

When installing, the device should be positioned correctly, it should not be at eye level. If there is a touch screen on it, the height is selected to ensure comfortable use.

Optimal sizes of built-in and hanging hoods for the kitchen

In modern high-rise buildings, the de facto standard is the use of devices with a width of 60 cm. Today, most models, both wall-hung and built-in, are optimized specifically for this standard. Models of a wide variety of designs are being developed, including inclined and angular, which allows everyone to choose something to their liking.

Often, for a built-in hood, you have to select a furniture set of non-standard sizes, so there are quite frequent cases when the kitchen has to be made to order. This is somewhat more expensive than purchasing standard-sized furniture, but from a design point of view it is much smarter.

When choosing a device that plays the role of an air purifying and ventilation device, you should evaluate its performance by choosing a more powerful hood.As stated earlier in the text, dimensions are not always an indicator of performance. Therefore, it is necessary to select a device based on both its performance and how it fits into the existing interior.
