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.

By the way, you said I had poor insulation and then asked for the U-value—let’s not twist things, okay?
Stick to that: Not smart...

By the way, you can plant on the properties above without any problem. Or do you all avoid planting trees because the drinking water pipe enters the house at that point? (It’s made of the same material as the brine pipes and lasts forever). Do you have no idea, or are you just trolling?
At least in my case, a drinking water pipe enters the house at one point (total area about 0.3m² (3.2 sq ft)), with a water temperature around 10 degrees Celsius (50°F).
A collector covers the entire area where it is installed and often experiences clearly below-freezing temperatures in winter, which cause the brine/coolant to release cold into the ground. Frequently, energy is drawn from the phase change of water in the soil freezing into ice. That is why nothing with deep roots grows where the collector is located.
And energy performance certificates or KfW information do not really relate much to the heating load. Also, if I remember correctly, Sebastian has a fully finished basement.

Or do none of you plant a tree because the drinking water pipe enters the house at that spot?Obviously, no one would deliberately plant a tree over utility lines.Thanks in advance for your general advice on heat pumps...
If anyone can share specific information about the different models, that would be great! Otherwise, my husband and I haven’t made much progress yet. We had a long conversation with an energy consultant who, mainly for cost reasons, also tends to recommend the exhaust air heat pump (with the supply air module, it would be comparable to a ventilation system). He assumes it will provide enough capacity for our house, as it is expected to consume only about 6 kW.
He tried to advise me against having a wood-burning stove...
