WHAT IS GEOTHERMAL?
In the simplest of terms, it operates very much like a refrigerator. When you open the refrigerator door to get your milk, there is cold air inside. If you are standing at the refrigerator with bare feet you can feel the warm air on your feet. The refrigerator separates the cool and hot air. In the simplest terms, geothermal systems separate temperature from the ground to provide heating or cooling. Geothermal means relating to the heat of the earth. These systems are highly efficient and use a small amount of energy to move a large amount of free energy. It provides you with the greatest opportunity to reduce energy cost. The energy is free, clean, environmentally friendly, and renewable.
In the heating mode, fluid is circulated through the pipes where heat energy is transferred from the ground to the fluid. Then the heat is transferred to the geothermal unit in the home. Heat is transferred in the home through duct system or a radiant heat system. Heating efficiencies are 50% to 70% higher than other systems.
In the cooling or air conditioning mode, the system is reversed. Heat is removed from the home and transferred to the loop fluid. As the fluid travels through the loop, the earth cools it. The earth serves as a place to deposit the heat. Cooling efficiencies are 2%0 to 40% higher than available air conditioners.
