Non-pressurized solar water heater principle
The non-pressurized solar water heater thermo-siphon system, its storage tank and evacuated tubes are installed as one unit on building roof. The storage tank is connected with the solar water heater, and many all glass evacuated tubes are inclined insert into the tank. The heat gathered by the evacuated tubes heats the water inward the storage tanks. Hot water goes into the storage tanks cause hot water rise up high. And cold water will go down into the evacuated tube to be heated again. Run by natural circulation, the system can work without electricity. The circulation heats the water in the tanks continually. The hot water flow rate of this kind mainly depends on height difference between the water tank and the hot water shower head.
