How Geothermal Works As the seasons move from spring to winter, temperature varies throughout the year. Some climates can vary from sweltering summers to cold winters; Meridian included. Did you know there is a fairly consistent temperature, regardless of climate or season, just below the ground? The Earth's crust absorbs 47% of the sun's heat (energy) and is retained in the ground a few feet underneath the surface. WaterFurnace geothermal systems extract this free resource with an earth loop. This innovative technology reclaims the sun's heat supplying your home or office with central heating and cooling. Geothermal Heating Using the earth loop, a WaterFurnace geothermal heat pump pulls the heat from the ground in the heating cycle. The geothermal system sucks the heat from the loops and delivers this warmed air through a classic duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling Conditioning air is just the reverse process used in the heating cycle. Warm air is pushed by the geothermal heat pump into the ground. By getting rid of the warm air, all that is left is cool air dispersing throughout your home. Heating your water during this process is "free".
