PROBLEM TO BE SOLVED: To provide a bath water heater system which, even if an abnormality such as the biting of a foreign matter on a prescribed three-way valve for joining a water heater device to a bathtub occurs, can eliminate such an abnormal state that the abnormality is relatively small, and thereby can appropriately eliminate such a failure that the operation of the whole system is liable to be stopped because of the abnormality of the three-way valve.SOLUTION: A prescribed three-way valve 2 provided at a bath water heater system is configured as follows: in such a case that valve body rotation control for rotating the valve element 20 is performed in a prescribed direction so that a state that one side limiter L1 is turned on is changed to a state that the other limiter L2 is turned on, in two limiters L1, L2, when the other side limiter L2 is not turned on within a prescribed time, such a valve body returning operation that a valve element 20 is reversely rotated to return the valve body to an original angle is performed, and thereafter, valve body rotation control for rotating the valve element 20 in the prescribed direction is performed again. |
