Geothermal Retrofits More and more residents in West Chester are realizing just how great WaterFurnace geothermal systems are for retrofit or replacement applications. The gains are obvious: WaterFurnace geothermal systems are counted as one of the most economical, energy-saving, environmentally friendly heating and cooling solutions available. Nearly all 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 unacceptable. 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 through pipes under your floors to heat your rooms.
