How Does a Geothermal System Work?

You may have already heard about geothermal heating and cooling systems and some of the benefits they offer: environmentally friendly, dependable, efficient, safe, and quiet. But you might feel a bit confused about how they operate. Where is temperature change coming from? We’ll try to explain how geothermal systems do their job.

Keep in mind as you read this post that no matter how many advantages geothermal heat pumps may offer, they do not work for all homes in all locations. Consult with professionals before you decide on taking a serious look at geothermal systems in Madisonville, TX. Rely on your local in heating and air conditioning experts for advice and installation: Ardon Maintenance.

The Geothermal System Basics

The earth maintains heat at a regular level. No matter the temperature above ground, a few feet below the surface the temperature remains at a fairly steady level that is warmer than the above temperature during the winter and colder during the summer.

Geothermal systems are heat pumps that harness this steady natural temperature difference and put it to use for you: instead of using the outside air as the exchange medium as standard heat pumps do, geothermal heat pumps use the earth’s constant temperature as the medium.

A geothermal system moves an antifreeze solution through plastic tubing buried in the ground around your house. Some geothermal heaters use refrigerant passing through copper tubes instead—local conditions determine which type will work best. These tubes are looped through the ground and the refrigerant/antifreeze transfers the heat from the ground up into your home where it is released to give you a warmer temperature. During the summer, the heat pump can reverse direction, so heat is removed from your home and put down into the ground.

Although geothermal systems cost more to install than many other HVAC systems, the U.S. Department of Energy estimates that the savings they provide from their efficient operation will return their cost in 5 to 10 years—and they will last a significantly longer time than that if given the proper maintenance.
