Ground source heat pumps are electrically powered systems that tap the stored energy of the earth. These systems use the earth’s relatively constant temperature to provide heating, cooling and hot water for homes and commercial buildings. Ground source heat pumps can be categorized as having closed or open loops. Closed loop systems have water or antifreeze circulating through plastic pipes buried below the earth’s surface.
During the winter, the fluid collects heat from the earth and carries it through the system and into the building. During the summer, the system reverses itself to cool the building by pulling heat from the building and placing it in the ground. This process creates hot water in the summer and delivers hot water savings in the winter.
