Geothermal Retrofits More and more residents in Omaha are realizing just how great WaterFurnace geothermal systems are for retrofit or replacement applications. The advantages are clear: WaterFurnace geothermal systems are counted as one of 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's no combustion and thus no need to vent exhaust gases. Geothermal technology is optimal for in-floor radiant heating, because heated water radiates throughout pipes below your floors to heat your rooms.
