Scott Brothers NC: Boone air conditioner repair, furnace repair and geothermal specialists
There are 4 basic methods how Geothermal or Ground Source Energy Systems tap into this alternative source of energy: 3 systems use a closed loop and one an open loop system.
Closed loop systems circulate a water-based solution through a "loop" of small diameter, underground pipes. In cold weather this solution absorbs heat from the Earth and carries it to the geothermal unit, where the heat is amplified and delivered throughout your house. In warm weather the process is reversed - excess heat is carried from your home and deposited into the Earth, keeping you refreshingly cool during the hottest summer.
