Abstract: The water heater includes a main body and a secondary tank. The main body encloses a receiving space and absorbs solar energy to heat water therein. The main body has a first inlet, a first outlet, and a steam outlet. The secondary tank includes a tank having a second inlet, a second outlet, and a steam inlet. The second outlet communicates with the first inlet of the main body via an inlet pipe, and the steam inlet communicates with the steam outlet of the main body via the steam pipe. Water enters the tank via the second inlet and enters the main body via the inlet pipe. Steam produced by the heated water in the main body enters the tank via the steam pipe to be further discharged or to condense into liquid water. The liquid water enters the main body again via the inlet pipe.
