Geothermal home heating
I've been researching the process of geothermal heating, but have a few questions I haven't been able to find good answers to. The fluid coming out of the ground will be about 50 degrees, how do you raise that to comfortable temperatures for home heating? Does it need a compressor? I thought it only used a heat pump. What exactly does the heat pump do? Does it only pump the fluid or does it also compress it? Any help here would be greatly appreciated.
