PURPOSE:To permit to set a hot-water temperature directly from each using taps and minimize the loss of energy by a method wherein the amount of combustion is controlled so that the maximum value of the hot-water temperatures, set by each mixing taps, becomes the desired supplying hot-water temperature of the tap-controlled hot water supplier. CONSTITUTION:Each mixing taps 13, 14 are equipped with hot-water temperature setting units, capable of outputting the setting values thereof to the outside, and a function to mix the hot-water, supplied from the tap-controlled hot-water supplier 1, with water, supplied from a water pipe 25, auto matically. A temperature controll circuit 7a compares the hot-water temperatures setting signals T1, T2 of the mixing cocks 13, 14 and selects the higher set temperature as the set value of a reference hot-water set temperature. On the other hand, the supplying hot-water temperature of the tap-controlled hot-water supplier 1 is detected by a hot-water temperature detector 6 arranged at a position 2 near the outlet of the supplier and the actual hot-water temperature signal is utilized as a controlled signal Tc. The temperature control circuit 7a compares the controlled signal Tc with the reference hot-water temperature set value and controlls a gas proportional control valve 5 so as to equalize both signals thereby controlling the amount of combustion of a burner 4. |
