Warmly recommended: Ventilation with heat recovery.

Modern buildings are insulated, keeping the heat in the house and saving a lot of energy. But modern ventilation units are needed so that this is not directly forfeited when you next ventilate. Your windows can remain closed, the air throughput can always be adapted to your needs and you will recover precious heat from the exhaust air.

Fresh air and heating costs

Did you know that you lose around 50% of your heat when you open windows to ventilate?

You should enjoy fresh air abundantly because this is our most important sustenance. The same holds in winter too, of course, when its is cosy and warm inside and icily cold outside. You need modern ventilation technology to bring sufficient fresh air into your home without throwing your money, in the form of heat, out of the window.

Exhaust air as a source of energy

Recover up to 90% of your heat out of spent air.

Only modern heat recovery manages the balancing act between healthy fresh air and healthy efficiency. Because it uses the energy of the spent exhaust air to heat up the inflowing air to a pleasant level in case of cold outdoor temperatures. The oxygen content remains high - your energy costs are reduced. A worthwhile exchange!
