The present invention generally relates to solar water heaters, in particular to solar water heaters using glass vacuum tubes as both solar energy collector and thermal energy storage device, without a hot water storage tank. A novel medium for thermal energy storage is disclosed, which utilizes the heat of solution of aluminum sulphate, comprising water and 40% to 47% of A12(SO4)3. The medium for thermal energy storage is sealed in plastic capsules which are soaked in water filling glass vacuum tubes. The invention also provides a water treatment device used for transmitting thermal energy stored in the glass vacuum tubes to tap water and adjusting the temperature of output water. The system works automatically by means of natural force and does not need electric pumps and electrical control units. 本发明般涉及太阳能热水器，特别是用玻璃真空管兼作太阳能收集器和热能储存装置、不需要热水箱的太阳能热水器。首先，公开了种新的、基于硫酸铝溶液的溶解热的储能介质，其中含有40％到47％的Al(SO)，其余是水。上述热能存储介质密封于塑料胶囊中，胶囊浸没在充满于玻璃真空管的水中。第二，公开了个水处理装置，用于把玻璃真空管中储存的热能传递给自来水，并调节输出水的温度。系统根据自然力自动工作，不需要电泵和电气控制单元。
