Specializing in Geothermal Heating and Cooling
How does Geothermal Heating and Cooling work?
Geothermal Systems operate by transferring heat to and from the earth through a series of polyethylene pipes buried in the ground. A solution of water and nontoxic antifreeze fills the loop and is continuously circulated by a small, low-wattage pump. The system exchanges heat with the earth's vast reservoir of low temperature energy and acts as a natural source for heating and cooling.
Like a refrigerator, a geothermal heat pump simply transfers heat from one place to another. When a refrigerator is operating, heat is being carried away from the food storage area to the outside, your kitchen. Therefore, cooling is not being added to the inside; heat is being taken out.
In the winter, water circulating inside the loop absorbs heat from the earth and carries it to the geothermal unit. Here, the geothermal unit uses the same technology as your refrigerator to extract heat from the water to produce warm air which is then distrubuted throughout your home using your duct system.
In the summer, the geothermal system reverses, removing heat from your home and distributes it into the cooler earth using the loop system.
