With refined shell construction without heating through the winter?

Can't you open the windows? Still don't understand the problem. Just go there regularly and air out. Of course, if you want to move into a still soaking wet new building and heat it to 20°C for 47 cents/kWh... why not.

PS: That's the much bigger problem, isn't it? Move in quickly, put cabinets against the still damp walls... and then it molds...

The exact difference is that the building is closed. As long as there is sufficient air exchange, everything is fine.

General excuses like Corona, war, are not sufficient when it actually comes to a dispute. It has been known for over a year that supply chains are disrupted. So why didn’t the GU order the heat pump early? He would have to explain to what extent the Corona pandemic prevented him from simply placing an order early (GU contract was already signed in 2020).

If delays cause additional costs of 1000€, I won’t start a dispute. It’s not worth the effort because before I would see the money (if at all) we would probably be close to a court date, where a settlement of about 500€ would be offered. And all the stress with lawyer fees etc... is not worth it.

Childcare is exactly the keyword. The new kindergarten is 30m as the crow flies from the house. Since August, it has only been a hassle that wastes time and fuel. That’s why we tend to move in. That wouldn’t happen until December anyway. Until then, cleaning and screed still have time to dry out. Since we already take the children to the kindergarten around the corner every day, we could also air out daily.

Can't you open the windows? Still don't understand the problem. Just drive there regularly and ventilate. Of course, if you want to move into a still soaking wet new building and heat it to 20°C for 47 cents/kWh... why not.

And conveniently, driving there costs neither time nor money. Just like moisture can be super easily ventilated out of an unheated building... To ventilate out, the outside air has to be drier than the air being ventilated out. The best way is to heat the air. But if you have to heat anyway and go there all the time, then you might as well move in and heat properly. The difference isn't that big anymore, you save the rent, and the original poster saves the stress with the kindergarten.

Is there still the possibility for an external chimney with a wood stove?
