Ground source heat pump vs. air source heat pump

Hello Jonny,

we are also building near you and due to budget and careful considerations will install an air heat pump as heating. Actually, we wanted a ground-source heat pump with a cylindrical ground collector, but the acquisition costs were simply too high for us because of the earthworks...

We also build in the area (Landkreis AS) and have decided on an air-to-water heat pump after careful consideration.

May I ask which manufacturer you use and which model?

Is supplied by Alpha Innotec the LWD 90.

May I ask how much the air-to-water heat pump costs you all in all??

How much living space do you have?

Is there a certain living space size at which one says that an air-to-water heat pump becomes unprofitable because it would have to be oversized?

I thought I heard something like that before.

I am also pleased that two home builders from my area have spoken up on my topic.
