Hello everyone,
I haven’t found the right answer yet while searching through the forum. Currently, we are considering two providers for building our house: one offers a ground source heat pump with borehole collectors, and the other offers an air-to-water heat pump.
Could you please share the pros and cons of both technologies? According to the seller, the air-to-water heat pump is considerably cheaper and only has a slightly higher resource consumption.
Thank you for your answers.
Yours, Scum

Hello,
Geothermal heating is more expensive but more efficient, while an air-source heat pump is cheaper but less efficient.
Specific conclusions can only be drawn when concrete data is available. Reliable information is only provided by an objective cost-effectiveness analysis.
General contractors or main contractors often purchase components at low prices without sufficient calculation or sizing. As a result, the systems often do not operate very efficiently. Heating load and heating surface calculations are a minimum requirement here.
The same applies to summer thermal insulation, which is largely neglected by energy saving regulations.
It is advisable to have summer indoor temperatures and cooling loads calculated to decide whether cooling might be necessary or required. The same applies to other areas of building services engineering, such as ventilation, solar systems, etc.
A seller wants to sell, so they are rarely objective and good advisors. 😉
Best regards.
