You won’t often see geothermal working because it is almost entirely out of site. This is because Geothermal can interact with your existing heat exchange system and the piping used is buried under ground.
Geothermal heat exchange is the process in which we use the energy from the ground to both heat or cool your home. This works both for heating and for cooling because the average temperature just 4-6 feet underground is an approximate 50 degrees year round.
How it works is in the summer you send your hot air into the ground and the earth absorbs the heat and sends cool air back into your home. In the winter you are pulling the warmer air from the ground to help heat your home. Often geothermal is acting as a supplement to the energy source you currently use to heat and cool your home.
There are four types of geothermal heat exchange methods. They are vertical loop, horizontal loop, pond loop and open loop. There are also many large scale geothermal energy systems not mentioned here.
There are several ways you can get started using geothermal today.
- You can become a geothermal advocate. Get educated and tell people what you know. You should consider geothermal in any new builds and retrofits you work on in the future. Find out what incentives are available and get some facts about what can be done in your area.
- Buy geothermal from a local contractor. Geothermal will save you money and keep your home feeling more comfortable.
