How Geothermal Works The temperature throughout the year will always vary no matter what climate you live in. For some climates that means hot summers that cool to ice-cold winters, and Myrtle Beach is no exception. What many people don't realize is that the temperature below ground (regardless of climate or season) stays pretty consistent year round. The ground is able to retain a higher rate of constant temperature because it takes in 47% of the sun's energy (heat) as it impacts the Earth's surface. WaterFurnace geothermal systems are able to draw from this free energy with an earth loop. This technology is then used to provide your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump utilizes the earth loop system to extract the heat from the ground. With delivery through a standard duct system, the geothermal system pulls heat from the loops and distributes it as warm air. Other choices are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling Cooling the air is just the reverse process used in the heating cycle. Warm air is driven by the geothermal heat pump into the ground. By getting rid of the warm air, all that is left is cool air radiating throughout your home. Heating your water during this process is "free". For more information on how to get started with a geothermal system in the Myrtle Beach area, contact J & J Air.
