WaterFurnace is the world leader in the innovation, design, and manufacture of geothermal heat pumps that can cut your heating, cooling and hot water bills up to 70%!

How does it work?

In the summer, the earth is your source of cooling. The heat pump absorbs heat from the air in your home and transfers it to water circulating in the piping loop where it is absorbed by the earth. This provides cool, dehumidified and comfortable air throughout your home. In the winter, the earth is your source of heat. Water circulating in the piping loop absorbs heat from the earth and carries it to the heat pump, where it is concentrated and sent as warm comfortable air throughout your home. The heat absorbed from the earth is carried to the heat pump, the heat is concentrated and sent through your duct system as warm, comfortable air. And, in all seasons, nearly free hot water is provided whenever the system is in use!
