A heat pump may actually provide more than three units of heat for each unit of electricity used. If a kilowatt-hour of heat is needed for comfort, it can be supplied by a one thousand-watt electric heater. To provide the same amount of heat the heat pump might use as little as 330 watts in an hour. This is a ratio of three to one. The ratio is referred to as the Coefficient of Performance (COP). Electric resistance heaters have a COP of 1 because they are using electricity to create heat. A heat pump moves heat from the outside to the inside of the home and vice versa, not using energy to create heat. We recommend. a COP of at least 1.8 at standard test conditions of 17 ° F dry bulb and 15 ° F wet bulb.
I am sure that explanation was as clear as mud. Let's look at it this way. Gas and fuel oil prices are going through the roof. It looks like the heat pump is becoming a better option.
