Thanks for the reply Emmett. The site is partially wooded, but the uimmediate site for the house is relatively open with few smaller trees to clear. I like the rubble trench idea because for one it seems to be less expensive, but also more stable in the long run as well as being a bit less invasive. I'm curious about the actual process though, If the house doesn't have a basement, and the floor is above greade which I assume it would be with a rubble trench. How does one insulate so that the radiant is not lost through the floor? I've been thinking about Geothermal for a while, and have begun to look into at most likely using a well or wells since I'd prefer not to trench and run pipe horizontally. Do you have experience with these systems?
