PURPOSE:To obtain a full automatic hot-water supplier, high in convenience and reliability, by a method wherein the supply of hot water, having a set temperature under the ON condition of a water flow switch, is permitted. CONSTITUTION:A set temperature 36 deg.C for kitchen is set in a hot-water temperature setting unit 50A, 36 deg.C for a washroom is set in the same 50B, 50 deg.C for bath is set in the same 50 deg.C and 42 deg.C for shower is set in the same 50D. The temperature of supplying hot-water for the shower is set in a preferential circuit 46 as the most preferential temperature. Upon using the shower, a water flow switch S4 and a transistor Q4 are turned on and the temperature of hot-water is determined by a resistor 54. In this case, diodes D1-D3 are grounded by the output of an inverter 45 and the transistors Q1-Q3 are cut off. As a result, when hot-water is supplied to a bath, for example, upon using the shower, the temperature of hot-water is limited automatically at the highest hot-water temperature of the shower. Further, there may be no possibility that the temperature of hot-water for the shower is reduced.
