Geothermal heating and cooling systems are one of the most efficient ways to moderate the temperature within a home or property. Because the ground absorbs almost fifty percent of the solar energy that our planet receives, below the Earth's surface remains at a constant moderate temperature. Geothermal systems benefit from using the stable underground temperature by implementing a pipe system called a loop. Water will circulate within the loop to swap heat between your home, the pump, and the earth. Weis Comfort Systems Inc., carries a variety of geothermal heating and cooling systems developed to cool and heat your home by implementing energy from the earth making these systems the highest quality of effectiveness while providing the best energy savings possible.
