Geothermal Retrofits More and more residents in Traverse City are learning just how great WaterFurnace geothermal systems are for retrofit or replacement applications. The gains are obvious: WaterFurnace geothermal systems are counted as one of the most dynamic, energy-saving, eco-friendly heating and cooling solutions in the industry today. Nearly all geothermal units are simple to install - particularly those replacing another forced-air system. Geothermal systems can be installed in areas where fossil fuel furnaces are unsuitable. That's because, with geothermal, there isn't any combustion and therefore no need to vent exhaust gases. Geothermal technology is ideal for in-floor radiant heating, because heated water radiates through pipes underneath your floors to heat your rooms.
