During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system pulls heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be used for a radiant floor system or domestic hot water heating.
In the cooling mode, the heating process is reversed – creating cool, conditioned air throughout the home. Instead of extracting heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop or used to preheat the water in your hot water tank.
Geothermal Vs. Geoexchange: What’s In A Name?
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 geothermal, geo-exchange, ground-water, ground-water assisted, ground-water-source, water-to-water, and even our company name, water furnace heating, and cooling.
