ABSTRACT:
A livestock waterer is described which is automatically heated through use of geothermal energy within the earth. Working fluid is housed within a reservoir below the surface of the earth, is heated to evaporation by geothermal heat, is transferred to a condensation chamber adjacent a water container, whereupon condensation of said working fluid occurs transferring heat to the water within the water container. Condensed working fluid is returned to the reservoir. An insulating lid is shown which allows demand use of the waterer by livestock and aids in the retention of heat within the water supply.
