Westech Solar City introduces the Westech passive solar heaters.
Westech passive solar heaters use a thermosyphon process of passive heat exchange based on natural convection. The water inside the evacuated tubes is heated by the solar radiation and rises through the tube to the tank. Hot water in the tube is replaced by the heavier cold water from the bottom of the tank, thus driving the water circulation around the collector and the tank circuit. The thermosyphon systems are simpler than most solar water heating systems since the need for both a circulation pump and a controller are replaced by the thermosyphon natural circulation.
Thermosyphon passive solar water heater is a self-sufficient system and requires no electricity, natural gas or propane to operate.
