Are you interested in becoming more “green” or interested in saving money on gas and electric bills? If so, you should ask the question: “what is geothermal heating (GH) and cooling?”. The answer to the question is, GH and cooling is an energy efficient alternative HVAC method that can significantly cut your energy usage.

Geothermal Heating and Cooling Explained
So what is GH and cooling exactly? It is a HVAC system that makes use of the power of the sun and of the energy found naturally in the earth.
While it may feel cold outside during winter and warm outside during the summer, this temperature change doesn’t happen deep below the ground. Below the frost line a constant temperature is maintained. In the Southeast, this temperature is 65 degrees Fahrenheit.
When you install a GH and cooling system, an earth loop is buried under the ground deep enough to be below the frost line. Liquid, which is also at a temperature of around 65 degrees circulates through these earth loops, the liquid is then moved to the geothermal heat pump.
The geothermal heat pump will use the energy from the 65-degree water to convert it into air. This is how your home will be heated or cooled. A distribution system will take the warm or cold air produced by the geothermal heat pump from the underground liquid, and will send that warm or cold air out into your home. When excess energy is produced, this can also be used to heat water if you have a desuperheater (an optional add on to a geothermal system). This can save you even more money because the cost of heating water is a significant part of most people’s monthly energy bills.
Why Does Geothermal Save Energy?
Aside from the desuperheater collecting extra heat to cut down on hot water costs, a geothermal system also saves energy because of its use of liquid from underneath the surface of the Earth. When 65-degree liquid is used as the starting-point for heating or cooling, only a change of a few degrees needs to be realized. This is very different and far more efficient than taking air that is 50 degrees and converting it into 70-degree air. Geothermal is, in fact, so energy efficient that Popular Mechanics indicated that average geothermal pumps may provide between three and four times the amount of energy that they consume.
