Geothermal Retrofits More and more residents in Myrtle Beach are realizing just how great WaterFurnace geothermal systems are for retrofit or replacement applications. The advantages are plain to see: WaterFurnace geothermal systems are among the most dynamic, energy-saving, environmentally friendly heating and cooling solutions on the market today. Most 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 unfitting. That's because, with geothermal, there isn't any combustion and thus no need to vent exhaust gases. Geothermal technology is ideal for in-floor radiant heating, because heated water circulates throughout pipes underneath your floors to heat your rooms.
