The distance from the gas stove to the hood according to the standard

Clean air, without smoke and odors in the kitchen, depends on the state of ventilation. In modern kitchens without an air purification system is no longer possible. And more and more people, installing new kitchen furniture, are asked questions, what are the optimal parameters of the device, and at what height to hang the hood. The correct distance from the hob to the hood plays an important role, and affects not only the efficiency of the ventilation system, but also for its security in general.

Hood installation standards

Experts recommend using the established rules for the placement of exhaust devices. They should not create obstacles for the housewife, working in the kitchen. At the same time, the system must qualitatively remove all odors and evaporation from the handed panel, without creating a fire situation.

There are standards for the installation of ventilation units:

• direct hood over the gas stove should be installed at a height - 75-85 cm;
• at direct installation of the unit, distance to the hood above the electrical panel - 65-75 cm;
• model with a sloping panel is placed above the gas surface at a height of 55-65 cm from the bottom.

These standard ranges are not calculated randomly. When calculating the parameter, at what distance to hang the unit, three factors must be considered:

1. Device power.
2. Design and configuration features of the room.
3. Human growth, using the stove.

power calculation

Calculate the power of kitchen hoods, the formula helps: L x B x H x 10 (or 12) = productivity in m3 / year. where:

• L is the length of the room;
• B - width;
• H - height;
• 10 or 12 - coefficient.

An example of that, how to calculate the power of the hood: L x B x H x 10 = 4,5 X 3 X 2,7 X 10 = 364,5 m3 / h. This means, that it will be able to process in one hour 364,5 m3 of air.

But keep in mind, that coefficients 10 and 12, provide assistance in finding maximum productivity, and no power reserve remains. In emergencies, the power of the unit may not be enough. Also, the calculation factors may vary depending on, which stove you are going to use:

• for gas stoves this figure may increase to 20 (due to the increased flow of combustion products, compared to an electric hob, over which there is evaporation only from food, that is being prepared);
• over the electric stove - to 15.

So., for kitchen with a gas stove, the power value will be: L x B x H x 10 = 4,5 X 3 X 2,7 X 15 = 546,75 m3 / year. It is recommended to make a small power reserve over the estimated when operating fans with maximum load.

Examples, how to calculate the hood, mentioned above, are suitable for the room of the closed type, if it has a closing door.

When the door is missing and installed ??arch, or a room adjacent to the living room (dining room), then the calculated data must be amended to take into account these features. You can use the table to quickly calculate the power.

Types of hoods by functionality

Modern hoods are divided by their functionality into 2 type:

• flowing;
• recirculation.

flowing

Flow-type ventilation devices discharge exhaust air into the ventilation system of the house or outside the building. Apartment buildings already have a ventilation duct, in which it is convenient to build in assignment.

But keep in mind, the device will work effectively only if, when this channel is individual for each apartment. If the ventilation shaft is common, the high-power unit will not be able to work at full capacity. In this case, it is better to make a separate branch on the street, with non-return valve installation (does not allow air to come from the street) at the exit.

recirculation

To this type of hardware technology, filtering the air inside the room without taking it outside. The air is drawn in by fans, is passed through double cleaning filters. Large particles are retained in the first filter: fat, hand, soot and so on. Going through another, more often coal - air gets rid of smells, and comes back to the same room. Read more about the principle of operation in the article on recirculation hoods.

Types of hoods for installation

Ventilation devices for the kitchen are divided according to the method of their installation on:

• flat;
• built-in;
• island;
• domed;
• desktop
• t-shaped.

flat

Suspended (flat) the devices are installed directly above the hob. They contain fans to suck in air and filters to clean it. It is quite easy to hang them: no need to insert and lay channels. The distance from the flat hood to the delivered gas or electric surface meets the standard. The height of the hood above the gas stove varies within 75-85 cm (65-75 cm - for electric).

Some models have a ventilation duct to connect the air outlet.

Built-in

This type of hood should be installed in a hinged cabinet, located above the stove. Due to its design, the knot becomes invisible in the interior. The device must match the width of the handed panels and cabinets, in which it will crash. The distance from the hob to the hood is calculated according to the same standard data. But it should be borne in mind, at what height are the hanging cabinets (if you plan to include the design in the finished furniture). When ordering a new kitchen, furniture makers will make the calculations themselves, by standards, as well as based on the width of the burner.

Built-in devices also include nodes, which crash into the countertop, behind the hob. They are also called desktop. The distance between the hob and the appliance is reduced to a minimum. The table top for such a combination of appliances should be wide - close 900 mm.

island

Island exhaust units are installed, when the stove is in the middle of the room. The device is attached to the ceiling, directly above the electric stove or gas stove. The height of the hood above the stove should be within the minimum and maximum, components from 75 to 85 cm to the gas stove. For electric - these figures are less than 10 cm.

Calculate the height Before installation, note the following, so that the housewife does not reach her head to the body of the device, being near the stove.

domed

Dome types of ventilation are fixed over the stove after the installation of kitchen cabinets. The advantages of this type are, that they can be decorated in different styles in the interior. Location height - standard.

inclined

Inclined type of ventilation devices are attached to the wall. At the same time the distance between the plate and the hood to come to terms with its lower edge. The minimum distance to the oven panel should be 35 cm, and the maximum (for productive work) — 45 cm.

T-shaped

T-shaped ventilation devices fit well into the interior in the style of Hi-tech (Hi-tech). They can be made of different materials using chrome parts, glass and stainless steel. The distance from the oven to the hood is calculated according to the instructions for this technique, but in most situations it overlaps with standard requirements.

Mains connection

By the rules, hoods are located above the wall cabinets, at a distance 5 cm from the top cover. Along with this you need to consider, where the corrugated pipe will be laid to the ventilation shaft. Access to the socket must be free, and the corrugation should not interfere.

If the appliance is built into the cabinet, then the socket can be placed there. It is recommended to lay the wiring above the cabinets, hiding it in a plastic casing. You can learn more about all the nuances in the article on connecting the hood.

so, it is very important to choose the right height of the ventilation system, to create a microclimate in the kitchen. If the device hangs too high, cleaning will be insufficient, with an underestimated location - fire may occur.
