Is moisture recovery in controlled residential ventilation sensible?

I can confirm that as well, 30% is not uncommon and you really have to have the whole house full of flowers to maintain the moisture. With a normal number of pots, that won't work; you have to water more often to prevent the plants from drying out.

We lived for almost 3 years in an apartment with controlled residential ventilation, but without [FRG], and therefore we consciously decided IN FAVOR OF the [FRG], as the air was too dry for us in winter.

Thank you. The opinions here seem to be unanimously agreed upon for once. Then the investment seems to have paid off.

I can only say that controlled residential ventilation with moisture recovery always provides us with pleasant air (1 winter and now the beginning of winter at least). For me, it should not be less now, but I am also sensitive in this regard (and I need my "voice" every day at work).

I would still be interested to know what you paid for your controlled residential ventilation system based on the ventilated area.

250 sqm ventilated area (7 supply air, 10 exhaust air) minus 1000 euros subsidy 6400 euros in EL.
