PROBLEM TO BE SOLVED: To provide an automatically hot-water-supplied bath which can accurately supply hot water to a bathtub until the surface level of the hot water reaches a set level and can shorten the supplying time of the hot water to the set level. SOLUTION: An automatic hot-water supplier accurately supplies hot water to a bathtub 5 to a set water level by detecting a prescribed water level in the bathtub 5 after the supplier supplies the hot water to the bathtub 5 until the circulating port (hot-water circulating port) 28 of the bathtub 5 is submerged and further supplying the hot water to the set water level when the detected water level is higher than the port 28. When the detected water level is lower than the port 28, the supplier supplies the hot water by first and second hot-water supplying amounts Q1 and Q2 , with the first amount Q1 being the amount to the detected water level and the second amount Q2 being the amount between the detected and set water levels. In addition, by utilizing that a circulating passage (hot-water circulating passage) 4 connected to the port 28 of the bathtub 5 is composed of a plurality of pipes (a return pipe 26 and a forward pipe 27), the hot-water supplying amount to the bathtub 5 is increased by selectively utilizing all or part of the pipes constituting the circulating passage 4. |
