Operating costs are difficult to estimate accurately and are dependent on a number of factors ranging from the climate the system is installed into the quality of the insulation of the space being heated to the cost of the fuel being used. They will even be affected by the temperature preferences of the people using the building. However, in most areas of the country where natural gas is available, it is a significantly less expensive heating fuel than electricity. In areas of the country dependent on oil or propane, the relative fuel prices could favor electricity as a heating source.
