How it works

Geothermal heating and cooling utilizes the earth's core temperature. And no matter the climate you live in, the core temperature of the earth stays constant. A series of pipes are installed in the ground, and transfer ground heat to and from the building, providing heating and cooling.

When used for heating, a geothermal system extracts heat from the ground by using the underground pipes. This heat is distributed throughout the building as warm air, usually through a duct system. This method of heating can also be used in water heating.

Geothermal cooling is the reverse process of heating. The geothermal system takes hot air from the building and circulates it into the underground pipes, where it is cooled. This cooled air is then circulated through the building, and the process is repeated.

Energy Bills


Efficiency equals savings, and geothermal heat pump systems substantially reduce operating costs, even when compared to the most efficient traditional systems. That means 60-70 percent savings over fossil fuels.

Geothermal heat pumps are designed for long life, assuring you savings for many years to come. Exclusive electronic controls provide worry-free operation. Each unit is backed by a 10-year limited warranty and underground pipe carries a 50-year limited warranty.



Over 70 percent of the total energy used in a typical home is for heating, cooling and water heating. With a geothermal heat pump system, up to 80 percent of this energy comes free, directly from the earth.

WaterFurnace has a long history of bringing innovative products, accessories and components like communicating controls to the market.



Geothermal heat pumps are a reliable and proven technology that have been widely used for more than 30 years. Millions of geothermal heat pumps are in operation worldwide, keeping people comfortable in homes, schools, hospitals, military facilities and many other businesses. Geothermal heating and cooling is a more stable source of energy than fossil fuels, and yields better temperature control.



Geothermal systems use no flame to heat your home, so dangerous carbon monoxide and gas leaks are eliminated. This added safety can contribute to lower insurance costs.

And with a noise-free operation, you'll have even more peace of mind. All WaterFurnace systems were designed and tested in a certified sound lab. They use double isolation compressor mounting techniques, which eliminate vibrations, and an acoustically lined cabinet to prevent noise from leaving the cabinet area.
