My loop is only about 7 feet down...but it is under the garage slab which has 2 inch foam under it and the rest will be under the driveway which will also have the foam under it. So I hope it will stay warmer this winter. The garage is finally up and closed in. It wasn't last winter. To the south the land goes up 2 feet, we cut into the slope to make room for the garage. So the loop should act like its 8 or 9 feet deep later when everything is done...at least thats the hope.

I can heat the tank of water with a wood stove for the testing...later if everything works it would be solar.

I have much insulating to do on the house to make this work. But the garage will be sealed better than the house. I also built it with 10" think walls for greater insulation. The rafters are "energy heel" type for more insulation also. No part of the slab touches the ground, everything is on top of the foam, I hope to have very little heat loss when it is all done.
