WaterFurnace manufactures and sells more geothermal systems for homes than anyone else in the business. Why? Because we offer a wide variety of residential geothermal products. Our dealers and installers are the most highly trained in the industry. And we are wholeheartedly committed to customer support. All that makes us the first—and smartest—choice for a residential WaterFurnace system: the system that's "Smarter from the Ground Up." 

Geothermal vs. Ground Water vs. Water Furnace 

Geothermal energy has been used to heat and air condition buildings for several decades, and, during that time, these geothermal systems have been called many different things. Some of the more popular variations include geo-thermal, geoexchange, ground-water, ground-water assisted, ground-water-source, water-to-water, and even our company name, water furnace heating and cooling. 

All of these terms, though, convey the same thought: use of geothermal heat pump technology to tap the energy in the earth's surface and drive a heating and air conditioning system for both residential and commercial uses. The result is a green or natural heat pump that saves energy and benefits the environment.
