Geothermal Retrofits More and more residents in West Branch are discovering just how great WaterFurnace geothermal systems are for retrofit or replacement applications. The advantages are plain to see: WaterFurnace geothermal systems are counted as one of the most economical, energy-saving, eco-friendly heating and cooling solutions on the market today. Most geothermal units are easy to install - 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 isn't any combustion and thus no need to vent exhaust gases. Geothermal technology is perfect for in-floor radiant heating, because heated water radiates through pipes underneath your floors to heat your rooms.
