Calculation of the power of kitchen hoods: advice of specialists
The kitchen extractor is considered to be one of the most necessary attributes in the house. But before you buy it, you should correctly calculate the power of the hood. Even if your purchase is issued under the brand name of an advanced manufacturer and is worth crazy money, it will still not cope with the task if you do not calculate the power correctly. Therefore, before buying such a cheap thing, you should familiarize yourself with the expert's opinion, inadvertently not throwing money away.
So, how to calculate the power of the hood? To do this, there is a universal formula that allows you to determine the most optimal option. You need to build on the height of the ceilings and the total area of the kitchen. The formula looks like this:
P = SxHx12
P is the estimated capacity, S is the area of the room, and H is the height of the ceilings. The figure 12 indicates the value of the SES norm for updating the air in the kitchen.
It should be noted that 12 - the average value, which can not be the only true, but in most cases this formula helps to effectively calculate the power of the kitchen hood.

Criterias of choice
When choosing a hood for the kitchen, follow the general advice regarding this equipment. If you want to purchase a system that will run smoothly for many years, it is preferable to buy a hood 10 times more powerful than the required minimum.
Thus, you will not only be able to hedge and receive a certain margin of power - you can significantly extend the life of the hood. To do this, you must set it to the middle mode, so that the device will not wear out so intensely.
When calculating the power of the hood for the kitchen, take as a reference the minimum figure of 600 cube / m per hour. If your hood does not have this power, it does not make sense. By purchasing such a hood, you will only acquire a massive, buzzing and useless piece of equipment that can not cope with 60% of fumes and odors.
For comparison, the average hood for the kitchen has an indicator of 350-600 cube / m per hour. And it remains only to hope that these 600 cube / m are real, not empty value on paper to attract customers. Buying hoods will not tolerate savings on quality, and if you do not want to pay twice, your calculation should be aimed in favor of power and functionality.
There is an opinion that for a standard small kitchen the model with an average level of air renewal is quite suitable. In fact, this statement is not supported by any calculations, here there is a so-called calculation by eye - to identify the average index of the kitchen with the average value of the ventilation system.
Relying on such statements makes no sense - you need to calculate the level of air renewal strictly according to the parameters of the premises of your kitchen.
The fact is that the small size of the room does not mean that you can save on quality. On the contrary, in a small room smells spread much faster, and if the owner of the apartment also smokes, we get another complicating factor.
Funnel location features
Another important point is the location of the funnel. From how you install the hood, the efficiency of its operation depends directly. That's why you should not choose the system only by external indicators, for design reasons. Undoubtedly, all household appliances should look harmoniously in the interior, but the first and main purpose is to fulfill the task.
In order not to be mistaken when choosing a hood, you should know all of its varieties.
This is a kind of dome above the stove or hob, connected to the ventilation pipe. This design is recognized as the most effective, but it is suitable only for premises with a large area.
The traditional option, which allows you to significantly save space in the kitchen. The system of work here is a little different - the calculation of the creators is that the intake air is not discharged outside, but is cleaned with filters and remains in the kitchen.
Thanks to this approach, you can avoid installation problems and save a lot in financial terms. The recirculation element itself is usually placed under the cabinet above the stove and does not take up much space.
Such devices are similar to domes, but the pipe for tapping to ventilation is built into the cabinet. Optimal variant, which is characterized by high power, compactness and low noise level.
On which of the options to stay - the choice is yours, but if you need a really powerful installation, dome and embedded patterns will do the best. Calculating the power of the hood is a responsible task, the result of which you will observe for several years, so you need to treat it with the utmost seriousness..
