Using Geothermal Energy: What is it?
Contact Us
You’ve probably heard of geothermal heating before, but what does it actually mean? “Geo-” means “earth,” and “thermal” means “heat.” There are two types of geothermal heating:
1. High-grade (direct). Three examples of high-grade geothermal heating include geysers like Old Faithful at Yellowstone National Park, which erupts every 92 minutes; hot springs such as Warm Mineral Springs in North Port, Florida, which has water at 87° Fahrenheit that feeds the lake; and power plants like the ones in California that use steam from deep wells to turn turbines to produce electricity.
“Geothermal heat pumps work anywhere in the United States.”
2. Low-grade (indirect). Symbiont Service uses low-grade, or indirect, heating to operate our heating and cooling systems. Low-grade geothermal energy is free energy below the Earth’s surface which we move to where the heat is needed using a heat pump. How does a heat pump work? A heat pump is a mechanical device that uses a refrigerant to move heat from a source (such as a well), to a heat sink (a place where heat is needed) such as a pool or spa. Geothermal heat pumps work anywhere in the United States.
Symbiont Service uses a heat pump called the Symbiont, which was originally designed by my father, Roy King, here in Englewood, Florida. The first Symbiont was installed in the early 1980s. We use Symbiont geothermal heat pumps to heat pools at locations across the Florida area—YMCAs, schools, universities, both city and county pools, residentials, and hundreds of condominiums.
Please reach out to us by calling or emailing if you are interested in a consultation to find out if geothermal heating is the right application for you, and if it is, we’ll provide a complementary survey of your pool for an installation estimate. We look forward to helping you.
