PURPOSE:To improve the pleasantness of taking shower by a method wherein in the case of the hot water feeder having a water quantity controller, the quantity of water set in the water quantity controller is changed periodically through a periodical change signal and in respond thereto, the amount of heating by a heating controller is also controlled. CONSTITUTION:Water entering a water controller 1 is heated by a heater 26 in a heat exchanger 14 so as to make itself hot water and the hot water is served from a hot water pipe 15. After the temperature of the hot water is stabilized, a signal generator 28 is operated manually or automatically so that a signal is generated to a drive device 21 from a water quantity changing section 28a to turn an adjust valve 17 clockwise or counter-clockwise to thereby change the throttling degree of a valve hole 17a. Accordingly, a control valve 4 is driven through a diaphragm 7 and the quantity of water is changed periodically. In this case, the heating controller 25 controls the amount of heating by the heater 26 to meet the quantity of water. Consequently, the massage effect of the shower is improved and the pleasantness of taking the shower is also improved. |
