here is the ground loop end of things, the circulation pumps into the heat pump.
That was from that crawlspace I dug at the end of the geo installation.
The heat pump, showing the waste heat loop to the nearby 52 gallon electric hot water heater that has not been turned on for 8 years now.
Flat panel solar collectors on south facing garage roof.
Solar glycol loop coming into the garage.
The happy gauge. To put that in perspective, it is at 121 f, at 7:21 AM in late March!! The sun has barely been on the panels.
Expansion header tank and piping, and not a good picture of the tiny heat exchangers. Everything was done to keep the glycol volume as low as possible. It gets really hot.
