How a solar water heater works?

Read on to find out more about how a solar water heater works. The basic function of a solar water heater is that it absorbs light with the help of collectors and then it is converted into heat energy. The circulating pump then passes the heat energy on to the water tank. This exchange is made possible with the help of the thermal regulator.
