Energy consumption A modern kitchen ventilator is not normally a major energy consumer. There are exceptions, however, and you should check certain things to avoid unnecessarily high energy consumption.
The most important factor is the air flow of the kitchen ventilator. As already mentioned, a large air flow results in reduced pressure, which must be compensated with replacement air from outside. This may not sound so dramatic, but in the long run quite a lot of replacement air will need to be heated to room temperature. This uses energy. A particularly hard winter will, of course, result in even higher energy costs. You should be wary of ventilators for which excessively large air flows are quoted. Or exaggeratedly high motor outputs.
You should also choose a kitchen ventilator with low-energy lighting. The fluorescent tubes with which we at Futurum equip our kitchen ventilators consume 7 times less energy than filament lamps. The fact that the service life of these fluorescent tubes is 10 times longer is also no disadvantage.
A truly efficient kitchen ventilator will also save energy every time you use it. Its efficiency means that you can run the ventilator for a shorter time by minimizing the need for secondary ventilation. Conclusion: the crows will think that you are a skinflint. But your taste buds will be eternally grateful.
The drawing shows the link between air flow and replacement air. When the kitchen ventilator is running, a certain quantity of air is expelled from the kitchen. This is compensated with replacement air from outside, which must be heated to room temperature.
