A heat pump is an efficient form of electrically based heating and cooling.A ground source heat pump is a highly efficient heating and cooling system that utilizes the stable temperature of the earth’s subsurface to provide heating, cooling, and sometimes hot water for buildings. Unlike other heating and cooling systems, which convert fuel or electricity directly into heat, a heat pump moves heat from one place to another, in the same manner as an air conditioner.The heat pump cycle is fully reversible, and heat pumps can provide year-round climate control for your home – heating in winter and cooling & dehumidifying in summer. Heat pumps cost on average 50-70% less to run than conventional cooling/heating systems.
