How Geothermal Energy Works
Geothermal energy is an extremely efficient and environmentally friendly way to heat and cool homes. With such a low environmental impact, we would expect that everyone would know and love geothermal, but this isn’t the case. We will explain how geothermal works so that you can make an informed decision when you decide how to heat or cool your home.
The core of the earth is very hot, and this heat can be felt even just a few feet beneath the earth’s surface. Geothermal energy uses and optimizes the heat that the core is constantly and naturally producing.
To get the heat, an underground piping system is installed, which is often referred to as a “loop.” The loop uses water to transfer heat energy from under the earth’s surface to your home. Energy can be found anywhere in the world and from 10 feet to a few hundred feet underground.
So how exactly does heat from the earth turn into warm air in your home, or even air conditioning?
In the winter, heat from the ground is absorbed into the water and carried to heat pumps. The heat pumps take the warmth from the water and distributes it through your home’s duct system, just like the heat produced by a furnace. It’s that simple. Heat is transferred from the earth to your home!
Knowing that geothermal heat is essentially warmth that has been moved, you may be wondering how that will help you in the summer. During warmer months, a geothermal system will take heat from your home and put it into the loop. As the water travels back towards the core, the heat that started in your home is absorbed back into the earth. Since the heat is gone, we are left with cool water. The cool water travels through the loop back towards your home and is processed into cool air.
The best part about geothermal energy is that the earth’s core is always producing heat, so there’s no shortage. If you’re interested in using the energy your land is producing or want to learn more, we would be happy to answer any of your questions!
