Abstract:
A solar water heater comprising:a water tank for holding water; a solar heating compartment for heating water having a top surface, a bottom surface, and at least one side surface wherein the top surface and side surface are constructed from transparent materials, said heating compartment further containing water tubing in communication with water in the water tank, a hot water outlet extending fully through the side surface of the heating compartment whereby water which has been heated within the water tubing may be released from the heating compartment, and at least one parabolic reflector positioned to reflect incident sunlight which has entered the heating compartment upon the water tubing for absorption thereupon, said heating compartment being sealed from the atmosphere to prevent the escape of heat into the atmosphere; and an air pump in communication with the water tubing within the solar heating compartment which may be selectively activated to create a partial vacuum within the water tubing, thereby causing water to continuously flow from the water tank through the water tubing and out from the hot water outlet by the siphoning effect.
