ᐅ Where can I get a ground source heat pump?

Hello,

our construction will start at the end of this month. Yesterday, we received the price breakdown for the individual trades. The price for the ground source heat pump seemed quite high to me, so I would like to compare options.

Does anyone know where I can get a ground source heat pump?
The drilling and underfloor heating are fine. I would just like to get a ground source heat pump, preferably from Alpha Innotec. I think we will need about 8 kW.

Can anyone give me a tip?

Thanks
Sabrina
