For the ultimate in energy savings that’s as dependable as the Earth itself, consider a geothermal heat pump system. Best suited for new construction, geothermal systems tap into the Earth’s surface to draw the energy and consistent heat that lies underground, or in a pond or well water. This becomes a source of heat to warm your home in the winter, but the source also becomes a heat sink to draw heat away from your home in winter.
