I recently built a new house and installed geothermal heat. I tried to do everything right, used an ICF foundation, Walltite Eco sprayed in 2x6 walls and over the entire roofdeck and rim joists and used triple glass with two gas layers for windows. The geothermal pumps and ground loops were designed by one of the most reputable dealers in the area. Since they did not do any of the hydronics or air ducting one of the bigger and more reputable plumbing shops in the area built my control board and designed the floor loops. A local shop installed the air ducts. The winter heating season has just barely begun and I am finding my power bill for the past month is $300. It is calculated that the house itself is consuming about $130 worth of power which leaves about $170 to run the heating system. $170 strikes me as kinda high even for a conventional heat system and especially for geothermal. The system is keeping the house quite warm but is running in excess of 50% of the time. What I am noticing is that I have a 20 degree drop across my floor manifolds (in 95, out 75). I've had suggestions that the temp drop is two great to be efficient and the power company has suggested that sometimes these systems are wired wrong and consume excessive energy. I would appreciate any tips on troubleshooting, if in fact things are as wrong as they seem to me. The system consists of a 3 ton water-to-air system and 4 tons of water-to-water with 5 hydronic zones, only three of which are in production at this time. Thanks.
