When you think about sustainable energy systems, solar and wind power are likely the first things that come to mind. You might not consider the thermal energy that lies just below your feet. Beneath the surface of the earth, temperatures remain consistently mild year round. Geothermal HVAC systems tap into this source of reliable energy to provide heating and cooling. Find out if now is the right time to go geothermal.
How Geothermal HVAC Systems Work
Like other types of heat pumps, geothermal systems move heat rather than generate it. In a typical setup, pipes are buried vertically or horizontally in the ground. Inside the pipes circulates a liquid that absorbs the thermal heat and conveys it to an indoor heat pump. During the winter, the system condenses the heat to make your home warm and toasty. In the summer, the ground system works as a heat sink for the hot air pulled from your home.
When it comes to energy savings, no other type of HVAC system matches geothermal heating and cooling. The heat pumps are up to 65 percent more efficient than conventional HVAC systems. They’re long-lasting too. You can expect to enjoy around 25 years of service from the indoor components and 50-plus years from the in-ground pipes. While they cost more to install than traditional systems, they pay for themselves through energy savings in 2 to 10 years.
Adding up the Benefits
In addition to financial savings, geothermal heat pumps offer other advantages. They can be installed as a new HVAC system or retrofitted to work with your existing equipment. A system with relatively few moving parts, they’re more reliable and need fewer repairs than other types of HVAC equipment. They’re extremely quiet too. A geothermal heat pump makes so little noise that it’s hard to tell when it’s operating.
