Geothermal Retrofits More and more residents in Reading are discovering just how great geothermal systems are for retrofit or replacement applications. The gains are clear: Geothermal systems are among the most economical, energy-saving, environmentally friendly heating and cooling solutions on the market today. Nearly all geothermal units are simple to put in - particularly those replacing another forced-air system. Geothermal systems can be installed in areas where fossil fuel furnaces are unsuitable. 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 hot water circulates throughout pipes under your floors to heat your rooms.
