Switching from electric heating to heating with oil can save you thousands of dollars a year in energy bills. Converting your current system is not complicated; you can supplement your heat pump with a boiler to provide warmer air through your existing distribution system. Electric baseboards and radiators can be replaced to accommodate a new hydronic (hot water based) system, or you can install a forced air system that also supplies air conditioning. Also, converting your water heater drastically increases the amount of hot water available in much less time.
