<P>PROBLEM TO BE SOLVED: To provide a user-friendly reservoir type hot water supply system capable of carrying out boiling with consideration to a lost heat quantity during hot water storage. <P>SOLUTION: The reservoir type hot water supply system 100 boils hot water in a hot water reservoir 10 to a predetermined hot water storage temperature. In a controller 14, after finishing boiling of the hot water in the hot water reservoir 10 in a midnight power time zone by a heat pump 12, a hot water storage temperature Ts in the hot water reservoir 10 is detected by hot water storage temperature sensors 34a-34e, a temperature difference ΔT between the hot water storage temperature Ts and a hot water boiling temperature Tm' of the heat pump 12 detected by a boiling temperature sensor 32 is stored, and in boiling of the stored hot water in the hot water reservoir 10 in a next midnight power time zone, the hot water boiling temperature Tm' of the heat pump 12 is adjusted by using the stored temperature difference ΔT as a parameter. <P>COPYRIGHT: (C)2008,JPO&INPIT |
