Compact Non-pressure Solar Water Heater Working Principle
The whole solar water heater system relies on the different density of cold water, thus non-pressure solar water heater also called thermal-siphonal solar water heater. The solar water heater system can work without the circulation pump and no heat pipe connection, cold water directly filled into the vacuum tubes, the vacuum tubes gather energy and heat the cold water, hot water goes up and cold water come down them be reheated. That how the water do circulation by itself.
