<P>PROBLEM TO BE SOLVED: To provide a hot water storage type hot water supply device, and a control method thereof, capable of preventing collapse of a hot water layer in a hot water storage tank. <P>SOLUTION: Temperature of hot water at primary side outlets of a heat exchanger 16 for heating and a heat exchanger 18 for reheating is measured by temperature sensors 23 and 25, and opening of flow regulating valves 22 and 24 is adjusted in accordance with the temperature measured. Hot water quantity supplied from the hot water tank 13 to the heat exchanger 16 for heating and the heat exchanger 18 for reheating is adjusted, thereby temperature of hot water to be returned to the hot water storage tank 13 is controlled to be roughly similar to the temperature of hot water close to a hot water return port 13b in the hot water storage tank 13. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
