Geothermal Retrofits More and more residents in Denver are discovering just how great geothermal systems are for retrofit or replacement applications. The benefits are easy to see: Geothermal systems are among the most economical, energy-saving, eco-friendly heating and cooling solutions on the market today. Nearly all geothermal units are simple 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 optimal for in-floor radiant heating, because heated water radiates throughout pipes below your floors to heat your rooms.
