How It Works

Ground source heat pump (GSHP) systems use ground heat exchange loops to extract thermal energy from below the ground to provide heating and hot water for your home.  This constantly renewable source of heat is channelled to the heat pump where it is converted to a higher temperature for domestic uses.
