Low Cost Ground Source Heat Pump

Objective

To build a ground source heat pump using common materials from the hardward store at low cost.

Proposed Technology

Utilize heat pipe technology commonly found in solar evacuated tubes. Use copper pipe threaded and capped at both ends for the heat pipe. The gravity fed evaporation/condensation cycle requires no motor or pump. Tubes can be placed in holes dug with a post hole auger. The fluid used in the pipe must boil at temperatures below 40 degrees F and should be non-toxic.
