f-pNo can you say how big your house is and which heating system you have installed? May I ask what the geothermal system cost in total?
: interesting... I have never heard of it until now... but I just read up on it. Unfortunately, you can’t find prices anywhere. Did you install it and can you provide information about price / performance?
Relatively expensive Google "Heizungsvergleich" - the first entry was an interesting overview. Although the investment costs are somewhat overestimated there in part (at least according to the first offers we received).

-> A friend installed them. I'll ask him about the price and how it performed during the first winter.
Size would be interesting, but it also depends on the insulation. On cold winter days, we used at most 15, usually about 10 kWh for hot water and heating. However, we also have a deeper borehole and fairly high brine values.
