Regarding the actual thread: Without a ventilation system, it must achieve 3.0, with a ventilation system 1.5. These are the requirements from the [Energieeinsparverordnung].

A brine-water heat pump achieves significantly more than an air-water heat pump. I'm not worried about that. No, not to exclude it. It's just that there is more funding for the brine-water heat pump than for the air-water heat pump, and the difference must also be factored into the calculation.
Well, but because it costs more. The subsidy is percentage-based (35%).
Correct. Just read the comparison of geothermal and air-water heat pumps in that thread. My reason for building will be:
1. Efficiency
2. I don't need this ugly outdoor or indoor module. So, space saving.
