Geothermal Retrofits More and more residents in Rochester are learning just how great WaterFurnace geothermal systems are for retrofit or replacement applications. The gains are easy to see: WaterFurnace geothermal systems are among the most efficient, energy-conserving, environmentally friendly heating and cooling solutions in the industry today. Nearly all geothermal units are simple to put in - particularly those replacing another forced-air system. Geothermal systems can be installed in areas where fossil fuel furnaces are unfitting. That's because, with geothermal, there's no combustion and thus no need to vent exhaust gases. Geothermal technology is ideal for in-floor radiant heating, because hot water circulates throughout pipes below your floors to heat your rooms.
