Geothermal heating and air conditioning technology is an attractive alternative to some Decatur homeowners because of its potential for increased efficiency. We’ve put together a short description of how it works and some of the potential benefits.
How Geothermal Heating and Air Conditioning Works
The temperature of the ground just below the surface stays pretty constant. No matter the temperature of the air above ground, whether it’s 100 degrees or 10 degrees, below the surface it’s always around 55 degrees Fahrenheit. Geothermal systems exploit this renewable energy source using a series of long pipes filled with a refrigerant that are buried in the ground. In the case of heating, the refrigerant absorbs heat from the ground and uses a geothermal heat pump in your home to transfer the heat to the air in your home. The air is then circulated using a traditional air handler. For cooling, the process is reversed: heat from your home is pulled into the heat pump where it is absorbed by the refrigerant and circulated into the pipes in the ground.
One of the obvious benefits to geothermal technology is that it doesn’t require you to burn any fuel in order to create heat. The heat comes from the energy of the sun that is absorbed by the earth which will never run out. This has the potential to save you money on your utility bills. Many geothermal systems achieve an efficiency rating of 400%. Even the most efficient furnaces do not achieve a 100% efficiency rating.
Because your source of heat comes from a renewable source, you no longer have to rely on a company to provide you with fuel to burn to heat your home.
Because it doesn’t burn any kind of fuel, a geothermal system doesn’t release any greenhouse gases into the atmosphere.
In many areas, using a geothermal system qualifies you for a tax credit or other reward from the federal government. Check with your local authorities to learn more.
