Low-pressurized or non-pressurized system is the most economic solar water heater which work stable and no need any maintenance. It must be installed on the top, such as roof, to get enough hot water flow pressure by the gravity.
Working principleSolar radiation is absorbed by the vacuum tubes, converted into heat, and transfer to the water, then, the hot water will rise up and cold water will go down automatically by the thermosiphon effect.
