Summary

A novel ground water heat transfer system is provided for low cost and high efficiency heat pumps and includes a deep well filled with water. An insulating sleeve which is smaller than the diameter of the deep well is placed in the center of the deep well so as to separate the well water into two portions. A water pump is suspended preferably below the water level and pumps the water from inside the insulating sleeve to the space between the insulating sleeve and the wall of the deep well in a manner which eliminates the dynamic lifting head. In an open loop system the water from the pump is first pumped to an heat exchanger and returned to the space between the insulating sleeve and the wall of the deep well. In a closed loop system the water from the water pump is pumped directly into the space between the insulating sleeve and the wall of the deep well and the fluid supplied the heat pump is pumped through a closed loop which is submersed in the space between the insulating sleeve and the wall of the deep well.
