How does a geothermal system=20 work?
Throughout the year, outdoor = temperatures=20 fluctuate with the changing seasons. However,=20 underground temperatures do not. In fact, about = four to=20 six feet below the earth’s surface, temperatures = remain=20 relatively constant year-round. A geothermal = system,=20 which consists of an indoor unit and a buried = earth=20 loop, capitalizes on these constant=20 temperatures. In the winter, fluid = circulating=20 through the system’s earth loop absorbs stored = heat and=20 carries it indoors. The indoor unit compresses = the heat=20 to a higher temperature and distributes it = throughout=20 the building. In the summer, the system = reverses,=20 pulling heat from the building, carrying through = the=20 earth loop and depositing it in the cooler=20 earth.
