Geothermal technology is designed to harness the earth’s energy, which is both renewable and clean. Among its many uses, geothermal energy can be used to heat and cool commercial buildings. The highly efficient systems that make this possible are geothermal heat pumps.
Geothermal heat pump (GHP) systems, also called earth-coupled or ground-source heat pumps, use a series of underground, liquid-filled pipes that exchange heat with their subterranean surroundings to keep buildings comfortable year-round. While air temperatures tend to vary as seasons change, geothermal energy keeps ground temperatures relatively consistent, providing a heat source when it’s cold outside and a heat sink that enables cooling when weather is hot.
