We are considering buying a house (in Switzerland) that has a geothermal heat pump heating system.
I am told that there is a borehole drilled into the rock below that is 200m deep and water is circulated and heated by the warmth of the earth and this is used to heat the house. Electricity provides the backup heating/additional water heating.
My question is are these systems any good, i.e. how much energy do you think would be saved? or are we still looking at a significant electricity bill in the winter? It's quite a big house (250m2) so I am worried about huge heating bills.
What about reliability, any particular worries? it seems quite a simple system on the face of it.
Does anybody have experience/knowledge of this kind of setup?
