6.3 Domestic Ventilation Units for DHW Preparation
New types of materials and construction materials have made it
possible to significantly reduce heating energy consumption.
Optimum thermal insulation combined with a good seal on the
outer shell of the building ensures that almost no heat is lost to
the outside air. On the other hand, extremely well sealed
windows prevent the necessary exchange of air in both old
buildings and new buildings. This effect leads to contamination of
the indoor air. Water vapour and pollutants accumulate in the air
and must be actively discharged.
How to ventilate correctly
Probably the simplest way to ventilate a room is to refresh the air
by opening a window. Ventilation at regular intervals by briefly
opening the windows is recommended to maintain an acceptable
living environment. To do this several times daily in all rooms is
