I have access to an auger for the tractor no problem, but I may need to make some sort of extension; might be 6 feet max now. . . .

Soil here is high clay, but where the clay isn't it is sandy.

Where my camp is (15 miles east) is blackjack.

My well water temp is 63~68 depending on season.

Actually no insulation at the moment; but very well sealed. I will be hanging sheet rock and filling the 2x4 walls with cellulose before the cooling season comes around.

Garage is 200 square feet, asphalt roof, metal walls concrete slab floor.

I don't want to get ahead of myself but the house with the same setup would be killer.

My "Plan" is to leave the condenser in place, building a box around it and pumping the water around it, I prefer the submerged idea, but then I'd have to re-charge the a/c unit.

No frost line here :-) Buried barrel/s sounds like a good idea to me. Best part is that way I would have x btu's pre transfered.

Heat would be cool also :-) Do you happen to know if the Heat/ Cool window units are heat pumps, or just heat strips?


I'm getting excited
