During the heating cycle, a geothermal system 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, a geothermal system air-conditions your home by reversing the heating process. Instead of extracting heat from the ground, it is extracted from your home and either moved back into the earth loop, or used to preheat the water in your hot water tank. Once the heat is removed from the air, it is distributed through the duct system in your home. Thus keep homes in Newfoundland comfortable during all seasons!
Newfoundland people living in homes with a geothermal units often say, “This home is the most comfortable we’ve ever lived in.” There are several reasons for this. The air temperature produced by a GXS is typically about 35°C. The air produced by a fossil fuel furnace or electric furnace is often heated to 50–60°C – much warmer than room temperature. This can create hot spots in a room. Moving around the room, you can often feel temperature differences of 3–4°C. Not with our new geothermal system! ~A Newfoundland Family
