at 6 feet the temperature does not vary season to season. That is why you aim for that depth or deeper.

It will be 50~53 before I start messing with it. This is easy enough to document when I get running, and I will start a thread about it in operation.

The loop will add or subtract heat energy from the earth around it. When winter is over the ground may be much colder, the sun recharges it.

I remember a couple of those small copper tube direct refrigerant systems, 6' deep warming the ground in the summer AC mode so much , that it killed the grass in the entire yard.

The Weller School near Fairbanks had a solar thermal system that dumped heat into the earth loops all summer to bring up the earth temperature.

my brother has a vac tube solar collector that he did that with. He would dump excess heat beyond what the AC load did. He had loop temps of 70 or so when he started heating with it in the fall.

Finally got the sewer brought away from the house and the last loop in, and all of it covered.

I used ferncos to attach to the sleeves that were poured in the footing.
