<P>PROBLEM TO BE SOLVED: To provide a hot water reservoir type hot water supply device capable of storing hot water in a hot water reservoir tank while suppressing heat residue. <P>SOLUTION: This hot water reservoir type hot water supply device comprises an auxiliary heating means 28 for heating hot water circulated in a hot water supply passage 27 connected with the hot water reservoir tank 2, and a heat load measuring means N for measuring heat quantity of the hot water supplied to a heat consuming portion through the hot water supply passage 27. In a predicted data calculation process where an operation control means manages the heat quantity measured by the heat load measuring means N as time-series actual heat load data, and determines the time-series predicted heat load data on the basis of the managed time-series actual heat load data, the time-series predicted heat load data is determined on the basis of the time-series actual heat load data obtained by correcting the time-series actual heat load data in a time zone of the occurrence of high-temperature heat load data, to a load reduction side when a high-temperature heat load data corresponding to a condition that a target hot water supply temperature is higher than a set hot water supply temperature available from the hot water reservoir tank 2, exists. <P>COPYRIGHT: (C)2009,JPO&INPIT |
