ᐅ Is Using a Construction Dryer Useful After Handover, or Is Window Ventilation Enough?

Hello everyone,
We are considering investing some money in purchasing a construction dryer. For us, the building handover is already complete. The person who conducted the blower door test mentioned that there is still a lot of moisture in the house. You can also notice it when entering the house or ventilating thoroughly.
We are wondering if a construction dryer is still useful when the painting work is already fully finished? Or is it counterproductive because the paint might lose moisture or something like that?
Or is ventilation alone enough? Regarding ventilation, we take turns with my parents-in-law since we basically travel between three locations. One day I go early before work and ventilate all open windows for 15 minutes. Then in the evening, the same again for 15 minutes. The next day, my parents-in-law ventilate once for 15 minutes. The following day, I do it again, and so on. On weekends, we ventilate more frequently when we are there, about 3 to 4 times.
Or does a combination of both bring the best results?
Thank you very much for your help.

Turned off the mechanical ventilation system yesterday because there was condensation forming on the fresh air vent directly on the facade during cold nights We have the same issue. In my opinion, this could have been better addressed (I would choose a different provider for the next house).

Please start by investing in some reliable hygrometers (starting at 12 euros), In my opinion, this is the only meaningful contribution in this thread. Just because someone says it’s damp doesn’t mean you should immediately start technical drying (which is always expensive). Please measure the indoor humidity (ideally over 24 hours, before and after ventilation, etc.)! Then you can decide on the next steps.
The same applies to the question about laying vinyl flooring. A floor is ready to be covered when the measurement values are within the required range. In case of doubt, please ask the screed installer, site manager, or your contract partner.
From experience: Floors typically slope toward the edges and corners. It might be a good idea to wait about a year before installing baseboards.

What did you do about it?
I just screwed a small sheet metal piece underneath and sealed it with silicone. Now I hope the condensation will drip off.

Bieber08156 Dec 2017 11:53The controlled residential ventilation system is from Pedotherm, the supplier chosen by my builder (the actual unit is from Vaillant, but that has nothing to do with the issue described). In front of the fresh air inlet with a DN150 (6 inch) diameter, there is a simple grille (weather protection grille, louvered grille). I bought a plastic profile that I want to install for condensate drainage (drip edge), but I haven’t gotten around to it yet...
For the next house, I would use a slightly larger duct and choose a better-designed grille (larger free cross-sectional area, drip edge for condensate). Such "weather protection hoods" do exist, but as far as I know, only for DN160 (6.3 inch).
