In fact I can supply exact numbers.
The left image shows our consumption at 11 c/kWh rate and the geo consumption at 4.2 cents. The right image shows air/air heat pump installed in the guest room also at rate 4.2 c/kWh and total consumption of the house. The basic load of the house excluding the heat or AC is about 1000 kWh/month. The 4.2 c/kWh is used only in the heating season. AC is charged at normal rate.
Our geo system was expensive due to fact that we have floor heating and AC as well. Forced air system is significantly cheaper. The geo uses waste heat to heat all hot water during AC season.
