Geothermal heat pumps and geothermal Air conditioning Systems
Efficient Heating & Cooling from the Ground Up.
 Geothermal Heat Pumps. Sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps - use the constant temperature of the earth as the exchange medium instead of the outside air temperature.
Even when the surface temperature varies from scorching summer heat to sub-zero cold, a few feet below the earth's surface the ground remains at a relatively constant temperature. Since this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer, geothermal heat pumps exchange heat with the earth to heat and cool your home providing a geothermal air conditioning and heating system.
As with any heat pump, geothermal heat pumps are able to heat, cool and, if so equipped, supply the house with hot water. Some models of geothermal systems are available with two-speed compressors and variable fans for more comfort and energy savings.
Dual-Source Heat Pump. A dual-source heat pump combines a standard air-source heat pump with a geothermal heat pump. These appliances combine the best of both systems. Dual-source heat pumps have higher efficiency ratings than air-source units, but are not as efficient as geothermal units. The main advantage of dual-source systems is that they cost much less to install than a single geothermal unit, and work almost as well.
Benefits of Geothermal Energy Heat Pumps. Compared to air-source heat pumps, geothermal heat pumps are more efficient, quieter, last longer, need little maintenance, and do not depend on the temperature of the outside air.
Costs and Savings. Even though the installation price of a geothermal system can be several times that of an air-source system of the same heating and cooling capacity, the additional costs are returned to you in energy savings in 5–10 years. Note that the installation of a geothermal air conditioning and heating system depends on the size of your lot, your subsoil and your landscape.
