Because it is easier to move heat to the cooler earth than into the sweltering summer air, Geo-Thermal Heat Pumps do not have to work as hard to cool your home. This efficiency has a bottom line - substantial savings reflected in your monthly utility bill. When heating, the compressor system of the Geo-Thermal Heat Pump uses the heat energy stored in the earth to efficiently heat your home of building while other heat pump systems are laboring to gather heat from the frigid outdoor air, or are even freezing up. Because Geo-Thermal Heat Pumps utilize such a large amount of the earth's stored energy, they are typically more efficient than even heaters which burn environmentally damaging fossil fuels. Geo-Thermal Heat Pumps exchange heat energy with the earth through a heat exchanger which is buried below the earth's surface.
Liquid is circulated through the pipes and the unit, channeling heat to or from the unit.
The amount of pipe and fluid necessary depends on a number of factors including local climate, ground composition and air conditioning and heating load requirements. The ground loop can be installed vertically or horizontally in trenches under ground and backfilled, leaving you with the uninterrupted natural beauty of your yard. There is no outdoor unit. Since the body of water exchanges heat with the earth, this can be and excellent and cost efficient application of the system. Finally, where ground water is plentiful, an Open Loop may be attached to the Geo-Thermal Unit.
