As others have said the heat pump is only good till outside temps around 38 degrees, so if outside temp is in the low 40's we use the heat pump. If temps are expected to go lower we switch to propane but we also use two 1500 ceramic heaters which are quiet compared to the furnace or the heat pump and if not paying for electric will offset propane usage. It is important to use the furnace if the temps are going below freezing if your tanks are heated by it. Some manufactures use electric heat blankets for the tanks so they would need being turned on for subfreezing temps.
