That is really great. Looks very good.. and cheap to run. Radiant floors have got to be some of the best heating. Is geothermal when you drill a deep well and run a closed loop system that takes residual heat from the ground and then uses heat exchangers to bring it up to 70 or so..? Runs off 3 phase 220 I imagine..?

I'd love to have the opportunity to build my own with everything I've learned. Of course the shop would be bigger than the house ;). Good job.

There are both open and closed loop systems. Ours is a closed loop with 500’ of coiled glycol-filled tubing ten feet deep out back. The evaporator and condenser change positions seasonally. There is also a fireplace for off-grid heating.

I don’t think it requires 3 phase.
