Most homeowners will find though that the extra money put out originally will be recovered in the monthly savings on their energy bill over a period of three to eight years. Homeowners in Sweden are already reaping the benefits of heat pumps in great numbers as studies have shown that over 30,000 homes in Sweden already have heat pumps installed in them.
Liquids called working fluids are used by heat pumps. These fluids have a boiling point that is much less than that of the temperature of the heat source. The fluids are also used to transmit the resultant heat created into the area intended to be heated. This is done by passing the fluid through a heat exchanger where the existing heat is removed from the fluid. This extraction is work and causes the temperature of the liquid to go up to the point that it boils and evaporates.
Once the liquid is evaporated, a compressor is used to add pressure to the system. This pressure adds additional heat to the system which is then removed and run through the ventilation system. Removing this heat causes the vapor to once again cool off, condensing it and making it a liquid again.
