ABSTRACT:
A solar heater system utilizes a passive anti-reverse siphon system to prevent the reversal of the fluid flow during evenings and other times when the ambient temperature is below the temperature within the system. The anti-reverse siphon system used functions strictly as a result of the geometry of the system and does not utilize either physical check valves or the immiscible fluid meniscus check valve system. Several embodiments include a wedge-shaped roof type version using a tandem or duplex system which heats first water for hot water use, with the hot water subsequently acting as the heating elment in the second of the tandem series for space heating, and other embodiments utilize a heat exchanger, a horizontally extended tank, a specialized corrugated hot plate for a flat plate solar collector which acts as the heating element for the system, and a system utilizing a special immersion heater in the anti-reverse siphon loop which can be externally energized if reverse siphon forces are so strong that the geometry of the system is inadequate to overcome them or if increased freeze protection is desired for the system.
