There are approximately 50,000 geothermal heat pumps installed in the United States each year. System life is estimated at up to 24 years for the inside components and 50+ years for the ground loop. 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.Įven 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 may be returned in energy savings in 5 to 10 years, depending on the cost of energy and available incentives in your area. Dual-source heat pumps have higher efficiency ratings than air-source units, but are not as efficient as geothermal units. These appliances combine the best of both systems. Simply attaches to your drill for fast liquid. ![]() Relative to air-source heat pumps, they are quieter, last longer, need little maintenance, and do not depend on the temperature of the outside air.Ī dual-source heat pump combines an air-source heat pump with a geothermal heat pump. Simply attaches to your drill for fast liquid transfer Ideal for pumping light liquids Emptying or filling -Tanks -Pools -Boats Transferring liquids between containers Delivers 900Ltrs per hour at 2000RPM Maximum drill speed -2,000. Some models of geothermal systems are available with two-speed compressors and variable fans for more comfort and energy savings. The GHP takes advantage of these more favorable temperatures to become high efficient by exchanging heat with the earth through a ground heat exchanger.Īs with any heat pump, geothermal and water-source heat pumps are able to heat, cool, and, if so equipped, supply the house with hot water. Like a cave, this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer. Depending on latitude, ground temperatures range from 45☏ (7☌) to 75☏ (21☌). They use the relatively constant temperature of the earth as the exchange medium instead of the outside air temperature.Īlthough many parts of the country experience seasonal temperature extremes - from scorching heat in the summer to sub-zero cold in the winter-a few feet below the earth's surface the ground remains at a relatively constant temperature. Geothermal heat pumps (GHPs), sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps, have been in use since the late 1940s.
