Nilan ventilation system with controlled heat recovery

I am a bit afraid of dry air. Do you have any experience?

I recommend a system with moisture recovery. This way, the air remains pleasant even in winter and does not become too dry.

Do you have such a Bieber0815? Because I also heard that the air is not dry in winter either

I believe it is hardly ever installed because moisture cannot be regulated at night and too much moisture can lead to mold.

In winter, the air becomes very dry with controlled residential ventilation and without humidity recovery

Here in Schleswig Holstein a well-known person now has 45% humidity in winter. Without humidity recovery.

I think that is a good value

Nobody is forcing you to do anything here. We are just sharing our experiences. If you consider 45% RH at about 3° outside and possibly 22° inside to be good, then so be it.

I, on the other hand, would not want to build without moisture recovery, because I know how dry it can get.
