It’s fantastic: a free source of energy! During the winter, it can heat your home by drawing heat from the ground. During the summer, it cools it and removes excess humidity. This system can save you up to 70% of costs from electric heating.
So how does it work?
Geothermal systems take advantage of the stability of the ground temperature. Underground pipes carry a fluid and heat energy is transferred from the ground
to the fluid and then to the geothermal unit in the home, giving warmth to the structure. Inside, the heat is then distributed through a conventional duct system or a hydronic radiant heating system.
The loops can be vertical or horizontal and are made of durable, high-density polyethylene, and are buried in the earth or submerged in a lake or pond. The type of loop depends on the size and configuration of the terrain.
A geothermal system is more efficient than regular heating and air conditioning systems as they can deliver four units of energy for every one unit of electrical energy used.
