What You Need to Know
This is a geothermal radiant floor system. The heat pump uses water from my domestic water well. The well was drilled an additional 300 feet from 200 to no 500 feet deep. I installed the radiant heat plates and PEX tubing under the floors myself. I also installed the insulation. Professionals made all the connections. We also repurposed my old 40 gallon gas fired hot water tank as the geothermal heat storage tank.
Periodically a spin-down filter needs to get cleaned.
Efficiency or Sustainability Improvements:
I sealed the attic, sills, floors, window frames & door frames. I had foam insulation injected into the walls bringing them to R-16. I added insulation in the attic, now up to R-49.
I want to stop using fossil fuels. My goal is for the house to be net zero. It's not quite there but it is close.

From exit 20 on I-93 head N&E on US-3 & NH-11 for 4.8 miles. Turn Left at light onto Bay Rd. Go 0.5 miles. Turn right onto Lower Bay Rd. Go 3.2 mile. If you think there is a fork in the road, bear right. (It turns to dirt at about 3.1 miles.) Turn right onto Kaulback Rd (dirt). 3rd drive on right. WARNING: Some GPS systems puts my address on an undriveable abandoned road in the middle of the woods about a mile away. PS. I am a terrible housekeeper but the energy stuff is cool.
