How Geothermal Systems Work

Geothermal systems are fairly similar to how a heat pump operates though it relies on the earth rather than exterior air to extract or deposit warm air. Basically, while air temperatures fluctuate constantly, the ground temperature at five to eight feet below the surface stays a consistent 55 to 60 degrees, which is much higher than average in the winter and definitely cooler than average in summer.

In the summer, the geothermal system pulls heat from the air in your home where it’s absorbed by temperature conducting fluid that is continually flowing within a closed-loop system of pipes. The fluid absorbs the heat in your home, travels down underground, allowing the heat to disperse with the ground acting as a heat sink before it travels back up into your home in a constant cycle. Heat is continually transferred out of your home during cooling cycles keeping your home cool on even the hottest days.

In the winter, the geothermal system works in reverse. Heat is absorbed from within the earth where it then travels into your home and is dispersed and able to circulate through your home.

Is a Geothermal Heating and Cooling System Right for Your Home?

Compared to traditional HVAC options, a geothermal system offers five key benefits:

  • Lower Utility Bills – Heating and cooling your home make up a large portion of your electric and gas bills, but a geothermal system offers incredibly low operating costs. Homeowners can see as much as 50 percent reduction in their utility bills in the winter and summer, saving you thousands of dollars a year.
  • Environmentally Friendly – Because you’re not burning fuel or using large amounts of electricity, a geothermal heating and cooling system is sustainable and the best option for the environment of any other method of heating and cooling.
  • Long Lasting Equipment – While furnaces, air conditioners, and heat pumps have a life span of around 10 years, geothermal systems have a very long life span. The pipes can be expected to last at least 50 years, while the rest of the equipment lasts between 20 and 25 years on average.
  • Improves Home Value – When selling your home, having a geothermal heating and cooling system in place can make your home more attractive to potential buyers and showing comps of your costs compared to surrounding neighbors can show the value of the system.
  • Low Maintenance – There are no heat exchangers, pilot lights, flue pipes or outdoor units to worry about, making them easy to maintain.

While the initial installation of the system can be expensive, the long-term value and benefit makes it an investment worth making for most homeowners.
