Geothermal Retrofits More and more residents in Boise are realizing just how great WaterFurnace geothermal systems are for retrofit or replacement applications. The benefits are obvious: WaterFurnace geothermal systems are among the most dynamic, energy-conserving, environmentally friendly heating and cooling solutions in the industry today. Nearly all geothermal units are a breeze 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 isn't any combustion and thus no need to vent exhaust gases. Geothermal technology is optimal for in-floor radiant heating, because heated water radiates through pipes below your floors to heat your rooms.
