PURPOSE:To provide a massaging effect when using a shower, by a method wherein a signal varying with time is selectively inputted into a heating controller for a heat exchanger and a driving gear for controlling the flow rate of a material to be heated. CONSTITUTION:After hot water temperature becomes equal to a preset temperature and becomes stable, a signal-generating part 33 is operated by the user or automatically, whereby a signal is outputted from the part 33. In this case, when a switch 36 is in a closed condition, the signal is added to a signal from a tapped hot water temperature setting part 31. Therefore, a set point of tapped hot water temperature varies with time. When a switch 37 is in a closed condition, the signal is transmitted to a motor for the driving gear 17, thereby varying the quantity of water. Accordingly, since the temperature of tapped hot water and the quantity of water vary from moment to moment, a massaging effect can be obtained by using tapped hot water for a shower. |
