Geothermal heating brings heat from the earth to a heat pump that transfers it into the building, in our case via in-floor radiant tubing and water heater. This requires drilling wells as deep as our water well. Though a larger initial investment, it is more efficient and saves money over time. Below are pictures of the drilling process, followed by grouting once the tubes are inserted.
Next, Jeff and John from the heating contractor connected the tubes and ran a line into the house. That will be hooked up to the geothermal unit later. Finally, Ryan who was running the digger closed up the tubing field and leveled off the area.
Next is filling in the floors and outside the walls. That was completed Thursday and Roy the plumber is working today. Pictures to follow soon.
