  • Ground Temperatures as a Function of Location, Season, and

    Amplitude of seasonal soil temperature change as a function of depth below ground surface. Vertical closed-loop earth heat exchangers are installed in boreholes 200 to 300 feet deep, where seasonal changes in soil temperature are completely damped out. Well-based open-loop systems also extend to this depth or deeper.
