WaterFurnace geothermal heating and cooling systems come in three basic configurations plus a fourth combo type, designed to meet the needs of your home and provide the highest efficiency and the greatest energy savings. And nearly all of our products meet or exceed the ENERGY STAR® requirements.
All-In-One Systems: Provide year-round comfort. Built to heat through the winter months and provide cooling all summer. WaterFurnace ground source heat pump systems replace the traditional indoor furnace/outdoor air conditioning equipment with one single unit.
Hydronic Geothermal Systems: These units are designed for heating and cooling water in applications like radiant floor heating, domestic hot water, and snow/ice melt. They can also be used to replace boilers and provide forced air heating/cooling when installed with an air handler.
Split Geothermal Systems: Provide installation flexibility with the capability to be installed with a remote air handler for whole house heating and cooling. Splits are also useful when installed in conjunction with a fossil fuel furnace for a dual fuel application for efficient operation in colder climates.
Combo Systems: Radiant hydronic heat is widely regarded as the most comfortable way of heating the home while all-in-one forced air is typically the most cost-effective. Combo units combine the best of both worlds, providing the luxurious comfort of radiant heat while providing traditional forced air heating as well — all from a single unit.
