This question really depends on what you are comparing a heat pump to. At today’s energy prices when you compare a heat pump to an oil furnace you will reduce your heating cost by about 65%-75%. If you compare a heat pump to electric heat, heating costs will be reduced about 60%-70%. A natural gas furnace rated at 80% efficiency will have almost the same operating cost as a heat pump. There are many factors when deciding on a new heating system. Ask a comfort pro from Temprite to help with your decision.
