<p><P>PROBLEM TO BE SOLVED: To provide a storage type hot water supply device capable of properly supplying hot water to a thermo-faucet by a hot water supply booster pump. <P>SOLUTION: This storage type hot water supply device includes a hot water supply control section for driving and controlling a hot water supply mixture valve so that a detection temperature of a hot water supply temperature sensor is kept at a hot water supply set temperature set by a remote controller, and the hot water supply booster pump disposed on the way of a hot water supply pipe, and rising a pressure of hot water/water to supply the hot water/water to a tap. Since the hot water supply control section includes a delay means for lowering the rotational frequency of the hot water supply booster pump, when the hot water supply set temperature set by the remote controller is set from a low-temperature side to a high-temperature side, and not immediately recovering the rotational frequency of the hot water supply booster pump to the original ordinary rotational frequency, when the hot water supply set temperature is switched from the high temperature side to the low temperature side, the water of high temperature remaining in piping is not swiftly supplied but the existing hot water supply state is kept for a while, thus the hot water can be continuously used in safety without having uncomfortable feeling. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
