Our Geothermal system has now been in operation for about 24 hours. I have included some photos with a brief explanation.
The new thermostat controls three heating stages and the two cooling stages. The two stage compressor provides heating and cooling stages one and two and the electric heat module provides the third heat stage in extremely cold weather. The Geo unit blower runs at low rpm (740) when no heat or cooling is required. This provides continuous circulation through out the house. The results are clean air and stable room to room climate control.
This is the entry point for the pond loop.
There is a significant amount of work involved to plumb from the entry point to the Geo unit.
I added two 220v circuits, a 50 amp for the Geo unit and a 60 amp for the auxiliary electric heat. Wire for both is 6 gauge copper.

Plenum air temperature monitor. At the time the photo was taken the unit was in circulation only mode.
Water pumps.

Now it follows that the high efficiency condensing furnace removed from the house needs to be installed in the shop. Again proving the adage that a man’s work is never done.
