Energy efficient ventilation with heat recovery

Modern buildings are insulated, keeping the heat in the house and saving a lot of energy. 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.
But did you know that you lose around 50 % of your heat when you open windows to ventilate? 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.

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!

All the benefits for you:

Perceptibly lower heating costs than with classic window ventilators - Up to 90% heat recovery
Well-controlled and demand-based fresh air supply
Prevents mould and moisture damage
Diverse retrofit options
