Geothermal systems work with nature, not against it. They emit no greenhouse gases, which have been linked to global warming, acid rain and other environmental hazards. Water Furnace provides an earth-loop antifreeze which will not harm the environment in the unlikely event of a leak. And much of the Water Furnace product line uses R-410A, a performance-enhancing refrigerant that will not harm the earth's ozone layer.
Unlike ordinary systems, geothermal systems do not burn fossil fuel to generate heat; they simply transfer heat to and from the earth to provide a more efficient, affordable and environmentally friendly method of heating and cooling. Typically, electric power is used only to operate the unit's fan, compressor and pump.
