Why is my electric bill so high with geothermal?
The system could be much more expensive if it’s colder outside and the heating set point is set much higher than it was with the propane system. Increasing the set point with geothermal is common. When dealing with propane, an expensive fuel source, homeowners will often set their homes to 65°F or less to save money.
