<p>PURPOSE:To provide a hot water supplier capable of immediately supplying hot water of a stable temperature by disposing a hot water storage type water heater consisting of a hot water storage tank containing therein a heat storage material and a heater, at the hot water supply side terminal of a main hot water heating unit. CONSTITUTION:A hot water storage type water heater 4 is composed of a hot water storage tank provided therein with a heat storage material 12 and a heater 13 at the lower par of said heat storage material. Cool water within a pipeline between a main hot water heater 1 and a hot water storage type water heater 4 at the terminal is heated by the heat storage material 12 within the hot water storage tank 11 of a hot water storage type water heater 4. Next, in a case where hot water is supplied in a state that the pipeline is filled with hot water, hot water supplied from a hot water supply pipe 3 of the main hot water heater 1 gives heat to the heat storage material 12 of the hot water storage type water heater 4. Further, when the hot water supply is stopped, and the temperature within the hot water storage tank 11 of the hot water storage type water heater 4 is lowered by heat radiation or the like the heater 13 is turned ON, and the heat storage material 12 is heated by hot water and heat is stored in the heat storage material 12.</p> |
