Solar water heater with automatic feeding tank is based on the natural circulation-thermosiphon phenomenon. It is the most economical type of solar systems for hot water application. Depending on the different density between hot water and cold water, a water flowing cycle is created in the tube. Hot water flows automatically upwards while the cold water from assistant tank flows down. The assistant tank can reduce the high pressure of cold water from water storage tank on the roof. When water tank is fulled with water, the ball valve inside assistank tank will close inlet automaticly. The water in the water tank will be heated from this natural circulation. And there is a stable water pressure. The outlet will supply enough hot water pressure and keep stable temperature balance to shower. It has the feature as the most economic type. It wan work indepently as well as work together with assistant tank. Electric element heater can be installed when it is rainy or claudy day. Workable at any time and enjoyable.
