...Actually want a geothermal heat pump but don’t know if it still works with the kfw55.
A geothermal heat pump with a ring trench collector only really makes sense if it is done during the excavation of the basement.
Subsequently, this can possibly also be done with a small excavator (<2t), but then an insane amount of excavation material has to be reshuffled.
For a deep drilling (vertical heat exchanger), the property must be accessible for heavy equipment.
A gas connection would already be there since an old house once stood there and the connections exist. But we also know that gas prices are rising quite a bit.
The electricity prices for the heat pump will then – possibly with some delay – also go up.
