Advanced ventilation systems – more than just air changes
Advanced ventilation systems safeguard regular air changes without wasting valuable energy. Subject to model, they can even provide DHW and central heating.
The increasing impermeability of new buildings and modernised residential dwellings in particular, calls for a continuous air change, for example, in order to avoid the growth of mould fungus and damage to the building. However, ventilation via windows is not very practicable as the sole means of ventilation. To ensure an energy efficient and hygienic minimum air change, ventilation via windows would have to occur four to six times a day for approx. 5 minutes each time. Heating would have to be turned off and windows fully open, making this virtually impossible. Mechanical ventilation systems reliably safeguard the necessary supply of fresh air, as well as energy efficient central heating and DHW.
