Calculate heating load to determine the size of the ground source heat pump

No, the exhaust pipe is stuck in the chimney flue - it has now basically "deflowered" it.

Last night I ran it full blast for about an hour and went from 7 degrees and 99 percent humidity to 27 degrees and something around 35 percent humidity

Absolutely, there is still exactly the same amount of water in the air :P But it can hold more and you can ventilate it away (let it be ventilated). Are you trying to dry your house right now?

Yes, of course nothing has changed there - you can clearly see it when the place gets cold again.

But yes, I just want to slowly get the moisture out and since there is no heating and the remaining craftsmen including me are freezing, I have set up the device for now.

Controlled residential ventilation is also running.

Unfortunately, I can't dry the screed with it.

Yes, and the weather is, at least here, lousy for drying, 10 degrees and endlessly humid.

Yep, here too - for the screed it was the most unfavorable time imaginable.

Rain, rain, rain.
Ventilate or bang...

My dehumidifier blinks over 55% there - I open the window and air out; the device doesn't care, that's what I wanted to say.
