LWW approx. 3500€
Geothermal approx. 13000€
By LWW, do you mean an air-to-water heat pump (commonly abbreviated as air-to-water heat pump as far as I know)?
What should one advise now? From my perspective, it is important that even with the gas variant, planning is done with low flow temperature and accordingly the underfloor heating is installed. Obviously, a gas condensing boiler is used. And of course, every selection must be based on a heating load calculation.
The packages would need to be specified now. Is it rather the best/most expensive/most modern gas condensing boiler competing against the oldest/cheapest air-to-water heat pump, or are the offered devices on a comparable level?
Does geothermal mean brine boreholes or ground collectors?
What is the usage scenario? Is hot water used often and for a long time in the shower? Or rarely and briefly?
Also relevant for the decision: Do you have money to burn or do investment costs matter?
