Geothermal Retrofits More and more residents in Mountain Home are discovering just how great WaterFurnace geothermal systems are for retrofit or replacement applications. The gains are obvious: WaterFurnace geothermal systems are among the most economical, energy-saving, eco-friendly heating and cooling solutions available. Most 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 unfitting. 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 circulates throughout pipes under your floors to heat your rooms.
