PROBLEM TO BE SOLVED: To provide a connected hot water supply system for compatibly attaining a short hot water filling time and an accurate hot water filling amount by applying general house combined water heaters even to a large bathtub. SOLUTION: Two or more combined water heaters 200a, 200b having hot water supply function and reheating function are connected in parallel between a water supply pipe 11 and each of a hot water supply pipe 12 and circulation pipes 13, 13, and their controllers 5a, 5b are connected to each other in a mutually communicative manner. The controller 5a on the side of connecting a remote control 300 integrally controls the two combined water heaters 200a, 200b. Hot water is poured therefrom at the same time when quickly filled in a bathtub 100 up to a right-before-set water level B.L. During a time from the reached right-before-set water level to a set bath water level, the hot water being poured from the sub machine 200b is stopped and the hot water being poured from the main machine 200a is kept on. The amount of the hot water to be filled is detected by integrating the flow amount of the hot water to be poured. COPYRIGHT: (C)2006,JPO&NCIPI
