When the water heater is working correctly, water will flow from the storage tank to the collector and back again. You can use the hot water at the top of the tank for washing and cleaning. You can change the flow of water so that the temperature is hot or warm as desired.
热水器工作正常时，水会从储水箱流到集热器，（温度升高后）再流回储水箱。你可以使用储水箱顶部的热水来清洗。你可以改变水流大小，从而使水温达到理想温度。
This solar water heater is easy to build and operate. It will last about two years before the rubber pipes need to be replaced.
这种太阳能热水器易于建造和操作。橡胶管（因为老化）大约每两年需要更换一次。
____________________________. As you might imagine, the heater will heat water only on sunny days.
正如你想到的，太阳能热水器只有在晴天才能把水加热。
