Ground Water Energy Systems draw water from an aquifer via a supply well, pass through the Geothermal heat pump's heat exchanger where heat is either absorbed or rejected, then returned to the aquifer via a return well. Ground water temperatures remain very constant (usually within a degree) though out the year despite wide variations in outside air temperature, therefore your Geothermal Unit will maintain it's super high efficiency no matter how hot or cold it is outside. Ground Water Energy Systems are ideally suited for homes that have existing water wells available.
