The kitchen is a complex space that is subjected to numerous daily loads. And in order for the air in the room to always be fresh, it is necessary to carefully consider ventilation and be sure to install an exhaust hood. It will work effectively in one case: if you correctly calculate the distance from the stove to the hood. Improper installation will not hinder cooking, but will make the appliance completely useless. Therefore, it is so important to know what types of hoods exist, what installation conditions are important to observe during installation.
Design features of exhaust systems
The principle of operation of the described device is extremely simple: the design provides a forced intake of dirty air and its purification from the products of combustion of gas, smell, smoke components that are formed during cooking. What is an extractor? This is a device that has a housing, a panel that provides air intake, a certain set of filters and a forced ventilation element.
All systems according to the principle of operation can be divided into two large groups:
- Appliances by the type of device on the forced air outlet outside the kitchen. Such an installation, located above the hob, ensures the complete removal of burning and soot, but to create a comfortable microclimate, it is important to carefully consider the flow of fresh air. Before deciding how to hang the hood, it is necessary to think over such technical points.
- The circulation principle of operation does not remove dirty air from the room, but cleans it with the help of a filter system and returns it back to the room. This cleaning takes a lot of time, but for its functioning it is not necessary to install an additional string of additional technical highways.
Note! Both systems are represented by several models. The correct installation height of the hood above the stove is calculated taking into account the design features of the described devices.
Types of exhaust systems
The suspended installation has a flat shape, it is attached to the bottom of the kitchen unit shelf directly above the electric stove or gas burner. Inside the structure, there must be fans that provide the process of suction of polluted air. It is passed through filters and cleaned, the distance between the stove and the hood when installing the suspended model can vary from 65-75 cm for electric stoves and 75-85 cm for gas hobs.
A built-in appliance is part of a cabinet or dome that is installed directly above the hob. This design feature makes the described device completely invisible. When choosing such a model, it is important to purchase one of them, the width of which will exactly match the width of the plate and the width of the kitchen cabinet. The distance between two objects is calculated according to standard parameters (more on them below). When choosing this design option, it is important to discuss such a design feature with furniture manufacturers even when ordering a kitchen.
Note! The described installation can also be built directly into the countertop, immediately behind the stove. With this combination, the width of the countertop must be at least 90 cm.
The wall-mounted version is an independent element of kitchen equipment that is attached to the wall above the hob. When choosing it, it is important to know that the distance is measured from the bottom edge of the hood panel. The minimum allowable indicator is 35 cm, the maximum distance from the stove to the wall air intake should be no more than 45 cm. Otherwise, the hood simply cannot cope with the tasks.
The corner model is designed for mounting the hood in the corner of the room.
Island systems are mounted to the ceiling in the center of a large spacious kitchen. They are selected when the stove is located in the middle of the room. The system is mounted directly above it, the hood should be at a distance within the existing minimum or maximum. The main thing is that the hostess herself does not touch her head to the body of the exhaust system.
The choice of model largely depends on the distance between the tile and the hood according to the layout of the location of the headset. As a rule, each manufacturer in the technical data sheet of his product indicates the recommended parameters for the height of the hood from the stove. Experts point out that such instructions must be zealously observed. What to do in the event that such parameters are not indicated in the technical passport of the product? You can try to calculate the distance from the gas stove to the hood yourself, taking into account a number of specific parameters. Let's designate the main ones.
How to calculate distance?
When deciding at what height the hood can be hung, it is necessary to put the safety of using two devices in the first place. As a rule, hood casings are made of plastic or metal. In order to prevent the possibility of spontaneous combustion of the hood housing, it must be installed at a distance of 65-70 cm from the hob.
The air purifier should not interfere with the hostess, cooking, using tall large pots.
The upper limit of the extraction distance from a gas stove or electric model should be able to draw air from the most polluted layers of air above the hob.
In many ways, the height of the hood above the gas stove and electric hob also depends on the power of the device itself, the area of \u200b\u200bits air intake. It is clear that it makes no sense to hang a low-power device (300 cubic meters / h) high. But powerful hoods in the kitchen (more than 600 cubic meters / h) can be hung, exceeding the average recommended figures.
The power of the hood must be calculated, taking into account the area of \u200b\u200bthe kitchen and the height of the ceilings. Calculations are made according to a certain formula: the area of \u200b\u200bthe room is multiplied by the height of the ceilings. So, for example, if the kitchen has an area of 6 sq.m., and the ceiling height is 2.5 m, the hood power must be at least 234 cubic meters / h.
Another parameter that must be taken into account when calculating the distance between the hob and the air intake is the air intake area. Its width should not be less than the width of the tile.
Summarizing such information, it is easy to indicate the lower and upper parameters.
- You can broadcast the air intake above the electric stove at a distance of 65-75 cm.
- But the norm for a gas hob with four burners is 75-90 cm.
- If the installation of the hood assumes its inclined position, then the permissible norm of the low limit is 55 cm, the high one is 65 cm. It is impossible to raise the device higher, since it will not be able to completely cover and take in all the polluted air.
Note! The figures given are average values. It is also important to consider the height of a person. If a person is tall, you can hang the hood even higher than 90 cm, but then you will have to purchase a more powerful device.
Where is the outlet for the hood located?
When deciding at what height to hang the hood, it is important to think in advance where to place the outlet for it. There are no clear instructions here, the main thing is that access to such a technical element is open and free.
If the described device is built into furniture, it is better to install the socket for it above the cabinet at a distance of 5 cm from the top bar of the facade. To hide the element, you can hide the socket in a plastic casing.
Generalization on the topic
So, answering the question at what distance from the stove the hood should be installed, experts pay attention to the need to comply with existing standards that meet the safety of operation of both devices. Any deviation from the rules will make the operation of the described system useless. Any decrease in the location can lead to the risk of spontaneous combustion of the installation, to a decrease in the comfort level of working with the hob.
