Presumably the former. The rest is all underfloor heating. Yes, it’s only about the basement. A few hundred € sounds very cheap. Acquaintances rather gave me four-figure sums as estimates.

So you can possibly give the signature that you accept if the basement does not get properly warm. How warm do you actually want it in the basement?

Do you have suggestions? Warm enough that you can use a room in winter for several hours without wearing 2 sweaters....Nota bene: The basement is fully insulated....

20kw is too much unless you also want to heat a pool... With 20kw we can easily heat our cabin.

I may be repeating myself. But 130sqm old building, continuously heated to 22 degrees, in deep winter at -10 degrees At, METERED heat output of the gas heating of 7.5kw. With 20KW you can heat 4-5 new buildings each with 160sqm heated area.

Ok, the opinion here in the forum is clear. I told the technician about it, but he insists and wonders that (without the additional radiators) only 14 kW instead of 20 kW are planned, and that even in smaller houses they mostly install the 20 kW. He also sees no problems or additional costs in operation with the heating at higher (max) power. Is this now ignorance or really just the fear that they cannot guarantee the operation...
