How Do Geothermal Systems Work?

Geothermal systems harness heat from the earth during the winter to heat your home and disperse heat back to the earth during the summer to cool your home. Also known as geoexchange systems, geothermal systems are a clean, renewable energy technology. 

 With geothermal systems, pipes are installed deep underground (typically called loops) and filled with a water-based solution. This solution aids in the process of absorbing or dispersing heat to and from the earth surrounding the pipes. That heated or cooled solution is then routed to a heat pump above ground that processes the heat or cooling from the water to air that can then be circulated into your home. 
So a basic example for heat would be: 
1. The earth absorbs heat from the sun. 
2. The water solution in the pipes absorbs heat through the pipes from the earth. 
3. The water goes through an above ground heat pump. 
4. The heat pump sends heated air through to your home. 
 Geothermal Facts

 Here are some facts you should know about geothermal systems.

 Geothermal systems work almost anywhere in the world. In fact, Iceland is the world's top producer of geothermal energy.

  • Geothermal systems can also be used to heat water for your home, saving you as much as 50% on your water heating costs - or more.
  • Geothermal systems are four times more efficient than a traditional HVAC system.
  • The average lifespan of a geothermal system is 25 to 30 years.
  • With the reduction in heating and cooling costs, a geothermal system typically pays for itself within five to 10 years.
