| Geothermal Drilling at SC |

| Drilling rigs are in place and are drilling down 320 feet for the installation of geothermal heat pumps. Geothermal heat pumps work like this ... Outdoor temperatures fluctuate with the changing seasons but underground temperatures don't. Four to six feet below the earth's surface, temperatures remain relatively constant year round. A geothermal system, which typically consists of an indoor unit and a buried earth loop, capitalizes on these constant temperatures to provide "free" energy. In winter, fluid circulating through the system's earth loop absorbs heat and carries it indoors. The indoor unit compresses the heat to a higher temperature and distributes it throughout the home. In summer, the system reverses, pulling heat from the home, carrying it through the earth loop and depositing it to the cooler earth.
Geothermal systems do not burn fossil fuel to generate heat; they simply transfer heat to and from the earth to provide a more efficient, affordable and envirnmentally friendly method of heaing and cooling. Because a geothermal system is three to four times more efficient than the most efficient ordinary system the end result is a more comfortable home and significantly lower energy costs. Now who wouldn't want that? |
