HOT WATER SUPPLYING APPARATUS

摘要

PURPOSE:To safely, finely and surely perform a plurality of remote controls by a structure wherein a set temperature signal is transmitted through a lamp wire to a receiving part so as to be converted into a temperature setting signal and then to be sent to a controlling part. CONSTITUTION:When a faucet 12 is opened or a switch 14' is pressed at hot water usage side, a set temperature signal is transmitted through a lamp wire 22 from a transmitter 13' to a receiver 25. The receiver 25 decodes the input signal and outputs a temperature setting signal to a hot water temperature control device 9. Accordingly, the hot water temperature control device 9 controls a three-way mixing valve 8 so as to control the mixing ratio between the high temperature water developed at a hot water storage heater 7 and the water supplied through a feed water pipe 6 in order to produce the hot water with a predetermined temperature. Due to the structure as mentioned above, independent temperature setting at a plurality of hot water usage sites and at the same time safe and sure remote controls can be possible.
