Has anyone used ground source heat pumps as the primary method of heating their home?
We have brought a house in Asturias …unlike several tales on this site, ours is a happy one and I´d recommend both CostaVerde Properties and Nortecasa who we brought through but more about that another time!
Anyway, as the house needs a complete renovation, we are interested in using GSHPs to heat it. It seems to be mainly used for coolig in Spain. Any advice, contacts, experience etc would be well recieved!
