I was just at a conference where one of the presentations was about green buildings. And the presenter was speaking about geothermal heat pump technology and how it saves energy and thereby money. I did a little looking around and the information I got made it seem that you still need to heat or cool the water in the system before storing it in the ground. Is this just insulation for the water heat or does the ground actually heat the water? Then how is it that this would work in a harsh winter? I will be looking for more information but was wondering if anyone here knew a good book, web-site, or just knew what was going on.
