An exciting and energy/cost saving feature of our future “net-zero” project in Durham is the geothermal heat pump. Geothermal heat pumps are able to heat, cool, and, if so equipped, supply homes and buildings with hot water. A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger—a system of pipes buried in shallow ground. In the winter, the heat pump removes heat from th ... Read full post »
