A heat pump is a machine or device that moves heat from one location (the 'source') at a lower temperature to another location (the 'sink' or 'heat sink') at a higher temperature using mechanical work or a high-temperature heat source. The difference between a heat pump and a normal air conditioner is that a heat pump can be used to heat a home as well as cool it. Even though the heat pump can heat, it still uses the same basic refrigeration cycle to do this. In other words a heat pump can change which coil is the condenser and which the evaporator. In cooler climates it is common to have heat pumps that are able only to heat the house. Common examples are food refrigerators and freezers, air conditioners, and reversible-cycle heat pumps for providing space heat. In heating, ventilation, and air conditioning (HVAC) applications, a heat pump normally refers to a vapor-compression refrigeration device that includes a reversing valve and optimized heat exchangers so that the direction of heat flow may be reversed. Most commonly, heat pumps draw heat from the air or from the ground. From Wikipedia under the

Q. Compared to a propane gas furnace, how is an electric heat pump? I hear that it's better to have a propane gas furnace as backup, but using primarily the electric heat pump will save a lot on energy bills. But I have also heard that the electric heat pumps don't provide adequate heat sometimes. Anyone have experience with an electric heat pump?
