How Geothermal Works

As the seasons move from spring to winter, temperature varies throughout the year. Some climates can range from scorching summers to cold winters; Long Island included. Did you know there is a pretty 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 sustained in the ground a few feet underneath the surface. WaterFurnace geothermal systems extract this free heat source with an earth loop. This innovative technology salvages the sun's heat supplying your home or office with central heating and cooling.

Geothermal Heating

In the heating cycle, a WaterFurnace geothermal heat pump employs the earth loop system to extract the heat from the ground. With delivery through a classic 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

The heating process is reversed in the cooling mode - creating cool, conditioned air throughout the home. Instead of pulling heat from the ground, heat is taken from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
