Ah great, you immediately have a way to save several thousand euros by leaving that out. Something like that is an expensive hobby for people who have money to spare.
Not yet. ;) Since March, they have easily doubled the costs for a typical single-family house with a garage. I am currently assuming around 5K just for the surveyor, who will then complain to me that he has had the same fee rates for years and has therefore suffered from inflation.

Why is this wasted money? Alternatively, I can only install an air heat pump outside. However, we have a rather small plot of land and don’t want to have such a box standing there -.-
He probably means ring trench collectors. However, with a small plot, it is not sensible either. There are also ground heat baskets, but I don't know how the required area is arranged.
Air-water heat pumps could also go up there depending on the roof...
Or just gas after all...
