The total length that exchanges the heat at the depth is important. If you got a big yard just got 8 feet deep and a hundred feet long and loop it. If not they go deep. In the Northeast the land of $$$ for an acre and rocks everywhere they usually get a well driller and drill a few hundred feet deep.
- foota 10y agoInteresting. Is that because of the rate of heat transfer through the rocks to get to the pipe or because you need a longer pipe to exchange heat with the ground?
- maxerickson 10y agoIf you don't have a big enough field the ground surrounding the pipe changes temperature too much.
