Hello,
My husband and I are currently trying to decide which heating system to install in our planned house.
I insist on having a ventilation system and a wood-burning stove in the living room. So the heating should be compatible with these.
Our chosen construction company has now offered us three heat pumps:
Air-to-water heat pump: Nibe F2040-8 with Nibe VVM320
Exhaust air heat pump: Nibe F750 P with supply air module SAM 40
Ground source heat pump: Nibe 1245-6 with deep drilling
My husband currently prefers the exhaust air heat pump because he thinks it works like the air-to-water heat pump but makes better use of the warm air from running computers... Everywhere I read, though, it says: "Avoid exhaust air heat pumps unless you are building a passive house."
Does the supply air module actually make it function somewhat like an air-to-water heat pump, but with better use of the warm indoor air?
The house is planned as a two-story timber frame construction with KfW 55 standard. To be honest, I am completely overwhelmed by this complicated heating topic. The more information I get, the more complex it seems.

In general, groundwater pumps depend on the type of groundwater available, meaning how suitable it is (maintenance costs) or whether it is feasible at all. Then, you need to obtain a building permit / planning permission.
Efficiency and initial costs are reasonable if the conditions mentioned above are met.

I once read about this, but 2-3 thousand euros for it is quite a lot. Of course, the hole can then be used for one of the two wells, but it could also turn out that using a groundwater heat pump is not advisable...

Is something like this very rare, or does it happen fairly often?
