ᐅ Costs of a Geothermal Borehole – Is It Worth It in Our Case?

Hello,
I have received a quote for a geothermal drilling. About €21,000 for 260 drilling meters (2 x 130 m (430 feet), water protection area, so the use of antifreeze is not possible), heating load around 8 kW.
Can someone tell me how this quote compares price-wise?
Or whether it is even worth pursuing geothermal energy further?
It seems quite expensive to me, especially when I read that some have paid only €6,000.
Best regards and thanks
Steffen

Being listed in the table is already a good sign, but in my opinion, the annual performance factor must still be verified after one year. This can be looked up though.If the heat pump does not achieve the annual performance factor, nothing happens. According to the BAFA information sheet, it is assumed that there are slight reductions from the calculated value. You do not need to pay back any money.
We received calculations from the manufacturer indicating an annual performance factor of over 4.5, which we submitted to the BAFA. It seems that online calculators do not take everything into account. Honestly, I did not fully understand the exact details, but the heat recovery system (HRV) apparently plays a role. The LWZ 504 is a combined unit with controlled residential ventilation.
