How Geothermal Works
Geothermal systems work much differently than ordinary heating and cooling systems. Conventional systems have to produce heat by burning some type of fuel, typically propane, natural gas or fuel oil. Geothermal systems don’t create heat; instead they collect and distribute it.
Did you know the earth absorbs and stores nearly half of the sun’s solar energy? As a result, at a depth of six feet, the earth maintains a fairly constant temperature of 45 to 70 degrees F. The geothermal system taps into that free renewable energy and puts it to work.
The earth’s natural heat is collected in the winter by a series of pipes called a loop system. Fluid circulating in the loop system carries this heat to the home, where it is compressed and released to raise the inside temperature.
In the summer, this process is reversed in order to cool the home. Heat is drawn from the home, rejected to the loop and absorbed by the earth. The result is a comfortable home all year-round.
Since most of the energy used for heating and cooling is free from the earth, geothermal systems are the most efficient and environmentally friendly systems on the market today.
Did You Know?
Installing a geothermal system in your home is equivalent to planting a full acre of new trees or the equivalent of removing two cars, and the pollution they create, from the road.
Through the American Recovery and Reinvestment Act of 2009, all Energy Star labeled geothermal heat pumps qualify for a 30% tax credit off the cost of your installation. This tax credit is not subject to a $1500.00 cap.
Geothermal systems are easy to install and are great solutions for retrofit and replacement applications and can also be used in conjunction with radiant floor heating systems. Geothermal is also a great option for homes where fossil fuel furnaces are unsuitable.
Geothermal continues to be one of the most efficient, energy saving purchases you can make for your home.
