An energy transfer system includes an energy transfer device, a water
inlet pipe and a water outlet pipe. The water inlet pipe may be connected
to a water inlet of the transfer device to extract water from a water
source. The water outlet pipe may be connected to a water outlet on the
energy transfer device to discharge water to the water source. The water
inlet pipe may extract water from a predetermined extraction depth, and
the water outlet pipe may discharge water into the water source at a
predetermined discharge depth.
