We don’t have a smart home, and can’t do much more to insulate it: parts are 200 years old, and the walls are a combination of thick rubble-filled stone and more recent block-work without continuous cavities. Currently we have a gas boiler for heating. On a hillside without suitable lawn etc for ground source heat pump. But we DO have a well. Not sure of the exact depth, but between 5 and 10 metres, with water surface about 3-4 metres below ground level. We don’t use the water for anything as we suspect heavy metal contamination from nearby lead mines. Is there any way this could be incorporated usefully in a ground-source heat pump?
