PURPOSE:To keep an amount of hot water more than a specified amount per one shower head in response to a state of water temperature by a method wherein a water supplying passage extending to a hot water mixing plug is provided with a water temperature sensor, and a controller is provided for controlling an opening or closing each of water stopping plugs in response to a sensed water temperature with a water temperature sensor. CONSTITUTION:An opening operation of each of water stopping plugs 14, 15 and 16 arranged at a branch passage of a hot water supplying passage 12 for each of shower heads 3, 4, 5 and 6 is allowed or restricted by a controller 17 and controlled thereby. In the case that a water temperature is lower than 10 deg.C in winter season, a less amount of hot water fed out of a hot water feeder, so that only one shower of a pair of body showers 4 and 4 or body showers 5 and 5 and a hand-held shower 6 as well as an over-head shower 3 is used and an amount of hot water is assured. In the case that a water temperature is more than 10 deg.C and lower than 20 deg.C, use of two kinds of showers is allowed in response to the increase amount of fed-out hot water and further in case that the temperature is more than 20 deg.C, a sufficient amount of fed-out hot water can be attained, so that three types of showers can be used. |
