Geothermal Retrofits More and more residents in Richmond are discovering just how great WaterFurnace geothermal systems are for retrofit or replacement applications. The benefits are clear: WaterFurnace geothermal systems are counted as one of the most efficient, energy-saving, eco-friendly heating and cooling solutions in the industry today. Nearly all geothermal units are a breeze 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's no combustion and thus no need to vent exhaust gases. Geothermal technology is perfect for in-floor radiant heating, because heated water circulates throughout pipes below your floors to heat your rooms.
