HOT WATER SUPPLYING DEVICE

PURPOSE:To supply hot water of certain temperature without requiring a complex control with the latent heat and sensible heat of a plurality of phase changing, heat accumulating materials utilized in respective heat exchanging sections and, at the same time, regulate the temperature of the supply hot water by regulating the volume of the supplied bath hot water to respective heat exchanging sections. CONSTITUTION:A plurality of heat exchanging sections 3, control valve 10 that is capable of regulating the volume of water or hot water supplied to respective heat exchanging sections 3, phase changing, heat accumulating materials 5 that have different melting points respectively and utilize the latent heat and sensible heat following their melting and solidification are provided. Further, a heater 4 that heats respective phase changing, heat accumulating materials 5, mixing section 6 that mixes the hot water from respective heat exchanging sections 3, temperature sensor 14 that detects the temperature of the mixed hot water, auxiliary heater 15 provided on the downstream side of the temperature sensor 14, and control section 19 that controls the control valve 10 and auxiliary heater 15 based on a set hot water temperature or the output signal from the temperature sensor 14 are provided.
