In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.

Referring to fig. 1, a first embodiment of a dual bladder water heater includes a housing 10, a first bladder 21, a second bladder 22, and a control device (not shown in the drawings). The first inner container 21 and the second inner container 22 are both located in the casing 10, and the first inner container 21 and the second inner container 22 are both provided with a water storage cavity 31 therein. The bottom of the first inner container 21 and the bottom of the second inner container 22 are both provided with a water inlet and a water outlet, and a first water conduit 32 extending to the top of the water storage cavity 31 is arranged at the water outlet. The water outlet of the first inner container 21 is communicated with the water inlet of the second inner container 22 through a second water conduit 33, and the bottom of the water storage cavity 31 of the first inner container 21 is provided with a heating device 41.

Cold water flows in from a water inlet on the first inner container 21, the water is heated by the heating device 41 in the first inner container 21, the heated water flows upwards, then flows to the second inner container 22 through the first water conduit 32 in the first inner container 21, the water entering the second inner container 22 flows upwards, and then flows out through the first water conduit 32 in the second inner container 22. The water can fully flow in the first inner container 21 and the second inner container 22, so that a dead water area is prevented from being formed in the first inner container 21 and the second inner container 22, and the breeding of bacteria can be reduced. In addition, the second conduit 33 is short in length and convenient to arrange.

Referring to fig. 1 and 2, the heating device 41 includes an electric heating tube wound in a disk shape.
