How Geothermal Works As the seasons move from spring to winter, temperature varies throughout the year. Some climates can range from fiery summers to chilly winters; Port Washington included. Did you know there is a pretty constant temperature, regardless of climate or season, just below the ground? The Earth's crust absorbs 47% of the sun's heat (energy) and is maintained in the ground a few feet underneath the surface. WaterFurnace geothermal systems extract this free resource with an earth loop. This innovative technology salvages 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 draws the heat from the loops and passes this warmed air through a conventional 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 driven 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".
