The Basics of Geothermal Heating and Cooling

bryant-geothermal-systemThere is an indoor and outdoor component of a geothermal heating and cooling system. The outdoor component is made up of pipes buried underground (the “ground loop”). The pipes are filled with liquid, or the heat exchanger. This liquid absorbs the temperatures found deep within the Earth and carries it to the heat pump. The indoor component brings air from underground and circulates it into your home at the desired warm or cool temperature.

Regardless of the conditions above ground, a constant temperature of 55 degrees is maintained just below the Earth’s frost line. Geothermal systems can successfully cool and heat your home without needing an energy source because this constant temperature is cooler than the outdoor air in the summer, and warmer than the indoor air in the winter. The fluid absorbs the Earth’s warmth during the winter and transfers it to the heat pump unit. When the seasons change to summer, the system absorbs heat from your home and transfers it back into the ground, leaving your home cool and comfortable.

energy-efficiencyThanks to the energy efficiency and environmental friendliness of a geothermal system, homeowners can expect large savings on their energy bills. Geothermal heating and cooling is typically 400-500 percent efficient, which means that for every one unit of energy they consume, they produce 4-5 unit of energy. Non-geothermal systems max out in the mid 90 percent range.

Experience consistent indoor temperatures year round, significantly reduced utility bills, as well as a reduced carbon footprint with geothermal energy systems!
