This is an open-loop thermosyphon solar water heater. Water circulates directly through the tank and the collector tubes simultaneously, speeding up the heating process. This system is stable and gives very reliable performance. The open-loop thermosyphon design is also the most economical and the simplest of all our solar water heating systems, making it popular in hot areas.
