I am a neurotic fresh air fanatic (actual words from my wife) and have a fully developed mold phobia. But even I consider this statement exaggerated. Simply run the controlled residential ventilation on level 2 throughout the first winter, and the moisture constantly leaves the place. Because of the very short construction time, we still have a lot of moisture in the solid construction, but thanks to the controlled residential ventilation, the humidity always stays in the green range.
To be on the safe side for building drying, I am now turning the heating one degree warmer in the first autumn/winter and for the time being have not installed an enthalpy exchanger in the controlled residential ventilation. But the windows have actually stayed closed nearly all the time since mid-September, except for the warm attic not connected to the controlled residential ventilation. In the latter, I see how the construction moisture drives the humidity up if I don’t air regularly.
My last post was before moving; now we have been in the new house since Friday.
THE controlled residential ventilation is definitely within the TOP 3 of the "things that are nice to have and that we blew money on."
When we first showered, we kept the window closed to see how it would go – the exhaust air is absolutely amazing. Overall – even going back to the bedroom in the morning without thinking "ugh, musty air," somehow there is pleasantly fresh air everywhere all the time. So far 10/10 would buy again.
And I also have the feeling that the ventilation is doing a good job of removing construction moisture. When we entered the house before the ventilation was started after 2 days, you could find condensation water inside on the windows. We no longer have anything like that; overall it feels like a good indoor climate. Let’s see how it continues.
