Hello everyone,
Does moisture recovery in a mechanical ventilation system with heat recovery make sense? I have read different opinions on this. Without moisture recovery, the air can be too dry in winter, especially for allergy sufferers. On the other hand, some say that in timber frame houses, it is better to keep the moisture outside and that the additional cost for moisture recovery can be avoided.
What is your opinion on this? Thank you

I can confirm that as well. A 30% increase is not uncommon, and to maintain the humidity at that level, you would need to have the entire house filled with plants. With a normal number of pots, this won’t work; you will rather need to water more frequently to prevent the plants from drying out.

I can only say that controlled residential ventilation with moisture recovery always provides us with comfortable air (during one winter and now at the start of the winter at least). For me, it shouldn’t be any less now, but I am also sensitive in this regard (and I need my "voice" every day for my job).
