PROBLEM TO BE SOLVED: To provide a remote control for a water heater capable of outputting important voice guidance without breaking off the voice guidance in the middle and hardly breaking off talk along the way. SOLUTION: This hot water supply apparatus comprises a master remote control 27, and a bath remote control 20 allowing talk between itself and the master remote control 27 through an interphone function and is provided with a voice guide function. Priority is given to voice guide content by the voice guide function. When talk by the interphone function overlaps with an output command of voice guidance by the voice guide function, the high-order voice guidance is output preceding the talk, and the lower-order voice guidance is output after the talk.
