PROBLEM TO BE SOLVED: To provide a comfortable bath hot water supply system which does not give discomfort to a user by controlling a hot water pouring temperature according to a hot water supply setting temperature.SOLUTION: In a bath hot water supply system, a hot water tapping flow passage from a heat source machine branches into a hot water supply side flow passage 4 and a bath side flow passage 5 in a downstream of a mixing valve 3. In the bath hot water supply system in which, when hot water supply is performed to the hot water supply side flow passage in a state where high temperature hot water pouring is supplied to the bath side flow passage, the high temperature hot water pouring is stopped, and hot water supply to the hot water supply side flow passage is executed at the hot water supply setting temperature in the hot water supply side flow passage, and after completion of the hot water supply, high temperature hot water pouring is resumed, the temperature of the high temperature hot water pouring can be performed at least at a first hot water pouring temperature and a second hot water pouring temperature which is lower than that. In the case where the hot water supply side setting temperature set on the hot water supply side is the first hot water pouring temperature, the temperature of the high temperature hot water pouring is the first hot water pouring temperature, and in the case where the hot water supply side setting temperature set on the hot water supply side is below the first hot water pouring temperature, the temperature of the high temperature hot water pouring is the second hot water pouring temperature.SELECTED DRAWING: Figure 1 |
