By arranging the second water flow detection device 82, the water flow of the second pipe section 312 can be detected, so that whether the water flow of the second pipe section 312 is stable or not can be judged, and meanwhile, the power of the booster water pump 60 can be controlled to adjust the water flow of the second pipe section 312. In this embodiment, the second water flow rate detection device 82 is electrically connected to the main controller 90.

In addition to the above differences, the water heater 100 and the components thereof provided in the present embodiment can be optimally designed with reference to the first to sixth embodiments, and will not be described in detail herein.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention, which are made by using the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
