Geothermal heat pumps are heating and cooling systems that use the earth's relatively constant temperature to provide heating, cooling and water heating for homes and commercial buildings. Sometimes referred to as Ground Source heat pumps, geothermal systems are either open- or closed-loop systems and can be installed vertically, horizontally, and even in an existing pond or lake. The type chosen depends on available land area at the installation site. Closed loop systems circulate water through high density polyethylene pipe buried deep below the earth's surface, providing cooling in the summer and heating in the winter and up to 70% of domestic hot water.
