    ahahahah...Lol..sorry Gingerbeard, i had no idea of your location. If i realized where you were i probably wouldn't have commented.(cement saws, jack hammers,backhoes dump truck..try explaining that to the neighbours) Im guessing your garage temps get WAY higher than my location. Southern Ontario. hahaha. Got fall temps out here tonight..53 degrees homegrown. i may give this some more thought to the buried pvc for next year though...

      Here in Michigan the level is 4', stays around 50° year round. Works well for geothermal. Some folks put their wood burners outside and pipe it in underground, avoids higher insurance while lower heating costs.

          Heat rises...so what is keeping the hot air next to the cooler concrete? I agree the slab is a great heat sink, but how to harness that sink? Maybe if your air ducting was insulated by (or submerged into) the concrete.
          I think geothermal cooling would be more efficient as well.

            Usually the piping is laid, pressure tested and then the concrete poured. Sorry to not completely explain that. And yes, I agree as well, geothermal is a great way to heat or cool and save money.
