Geothermal Heat Pumps utilize the energy below the surface of the earth to transfer heat to and from a building as a form of space conditioning or water heating. The ground acts as a heat source in the winter and a heat sink in the summer.
According to the EPA, Geothermal Heat Pump Systems are the most energy-efficient HVAC systems available. Large commercial facilities can especially benefit from investing in these types of systems because they are incredibly cost-effective and can help to greatly reduce carbon footprint.
Because GHPs are ultra-efficient and do not burn fossil fuels, they greatly reduce on-site carbon emissions and help to reduce overall carbon emissions used to power a facility.
