           This model operates to feed water automatically. Using thermostatic system- depending on the different density between solar hot water heater and cold water, a water flowing cycle is created in the tubes. Hot water flows automatically upwards while the cold water flows down. The water in the storage tank will be heated from this nautal circulation.
