Geothermal Heat Pump

About 20 feet below its surface, the earth maintains a constant temperature between 52-57 degrees Fahrenheit, due to the sun's heat and the insulative qualities of soil and substrate. A geothermal heat pump, or ground source heat pump, uses the relatively constant temperature of the ground to transfer heat to a structure for heating and domestic hot water, or to remove heat from a structure for cooling.
A geothermal heat pump is the most cost-effective way to save electricity, because it saves up to 70% when compared to conventional heating systems. Averaging about 1 kWh to run, a geothermal heat pump can save up to 5kW in reduced heating costs. Even though the initial installation is costly, the savings in reduced heating expenses help recoup the installation costs in a short period of time and continue to reduce heating expenditures for years to come.  
Beaver Ponds EEC utilizes close to 3,000 feet of horizontal closed loop configuration, which is buried 6-7 feet deep beneath the Alpaca Corral. The geothermal system supplies heat to the domestic hot water and radiant floor heating system in the living quarters, classroom, and greenhouse.
