In this article, we will break down the cost of installing a geothermal system in your home and help you determine if it’s the right option for you.

1. What is a Geothermal System and How Does it Work?

Geothermal systems are heating and cooling systems that transfer heat to and from the ground. They use the constant temperature of the earth to provide a comfortable living environment and save energy. Unlike conventional heating and cooling systems that burn fossil fuels to generate warmth or cool air, geothermal systems utilize the heat that is naturally present in the earth.

How Does a Geothermal System Work?

A geothermal system consists of three main components: a heat pump, a ground loop, and a distribution system. The heat pump works like a refrigerator, whereby it transfers heat from one location to another. It extracts heat from the earth through the ground loop, which circulates water or an antifreeze solution through underground pipes. The heat pump extracts the heat from the fluid and delivers it to the air for heating the building or removes heat from the air to cool it.

The distribution system then distributes the heated or cooled air through the building’s ductwork or radiant floor systems. The heat absorbed from the earth is a renewable resource, and the heat pump requires electricity to circulate the fluid, making it an efficient and eco-friendly option. Overall, a geothermal system works by drawing on the earth’s natural heat to provide a consistent and reliable heating and cooling source for residential and commercial buildings.
