ᐅ Cost Breakdown Heat Pump – Heat Pump with Ground Collectors

Hello,
I have to say, I’m really overwhelmed by the complexity of heating systems. Apparently, each type comes in about 30 different models.
Could someone provide an example overview of the costs involved and which heat pump would be suitable for a 125 m² (1,346 sq ft) single-family house if I want to plan a heat pump with ground collectors from Vaillant?
geoTHERM VWS 63/3? And what exactly is covered by the 4000 euro subsidy?
Can anyone recommend an affordable company in North Rhine-Westphalia (NRW)?

Ours is located in the basement – once again, an advantage of having one.
Although 42dB is very quiet...

How does passive cooling actually work? As I understand it, it should help to partially regenerate the borehole, right?
And another question:
Our heating engineer now wants to connect an 8 kW heating system to a 6 kW borehole—is that sensible? I wouldn’t worry about freezing since the maximum demand is around 6 kW anyway. The COP of the 8 kW system is almost the same. Is it then just the slightly higher initial costs, or is there another reason not to do this?

Sebastian7924 Aug 2015 20:18I can’t tell you – our heating system and the borehole were selected together. The heating system can actively cool.
However, the heating system can deliver 8kW, as it cannot modulate.
Why don’t you choose 5kW for a 6kW heating load?

toxicmolotof24 Aug 2015 21:45Is your utility company allowed to cut off your heat pump electricity? In that case, having an 8kW system definitely makes sense to partially compensate for the shortage.
What exactly do you want to regenerate at the source? Especially in winter? Cooling does not regenerate anything because there is no cooling. The seasonal change from summer to winter is probably negligible or only has a short-term effect.

toxicmolotof24 Aug 2015 22:03And why should it be done that way? Heat pump electricity is indeed subsidized. But then an 8 kW (8.0 kW) pump doesn’t make sense, or is the 6 kW (6.0 kW) only the heating demand? There is also hot water in addition (without solar).
