Hello everyone,
for our planned single-family house with 2 floors and a basement, we have decided on a central ventilation system for all rooms with heat recovery within the thermal envelope. The brand and model are not yet determined.
I have read here on the forum a few times about an additional moisture recovery feature (MRF?), since otherwise the indoor air tends to become too dry (of course, the ventilation system also removes the moisture that naturally occurs in the room, which usually makes the air feel comfortable). I wanted to ask if anyone can confirm these issues and whether this is more common in timber frame houses or also occurs in brick houses?
Did you install additional moisture recovery in your ventilation system? How much extra cost does it involve? I assume there are also additional maintenance costs because it involves another motor and related components.
Best regards

I would at least invest in a humidifier. Otherwise, it’s already harmful to your health. What’s the point? It runs around the clock, and after one hour the air is completely replaced.

Marketing nonsense from someone who doesn’t offer an enthalpy exchanger?Maybe. I don’t know, that’s why I started the thread. But it does seem like a very sensible investment.
