We are currently planning our single-family house (145 sqm/1,560 sq ft) with geothermal heating that requires drilling. Has anyone recently chosen this type of heating system and can offer advice regarding manufacturers or what to consider? We are complete beginners, so please keep explanations simple. However, I am interested in all information.
So far, we have received quotes from Viessmann and Lechner Massivhaus, which vary quite a bit in price. We don’t want to build cheaply, but reasonably.

Definitely modulating. Nibe and AIT (which are identical internally) are good options. However, there are other good alternatives as well. The question is what your heating contractor or general contractor will install and whether there is local distributor or support from the manufacturer available in your area.
Viessmann is an option, but they are not considered top performers. I am not considering Lechner, since it’s not even recognized by the annual performance factor calculator.
More important for an efficient heating system is a low floor heating supply temperature, for example 30°C (86°F), without a heating buffer tank and without closed heating valves.
Instead of drilling, a horizontal collector (ring trench collector) might also be an option.
It is also important to clarify whether an internal water storage tank is sufficient for you, or if you want a separate hygienic storage tank or fresh water tank.
