<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply system capable of operating according to the needs of a user. <P>SOLUTION: A hot water connection unit 20 generates hot water with a fixed temperature at a set temperature or below the set temperature by mixing low temperature water if necessary with preheated hot water generated by a solar heat using water heater 10, and the generated hot water is introduced into a direct-heating storage type bath water heater 30. The bath water heater 30 can switch to a normal operation mode controlling combustion of a burner 32 to make the tank temperature of a hot water tank 31a to be a can body set temperature, an energy saving operation mode forcedly stopping combustion of the burner 32 during delivery of hot water with the set temperature from the hot water connection unit 20, and halfly energy saving operation mode burning the burner 32 till when the tank temperature reaches the can body set temperature even if, just after starting of operation, hot water with the set temperature is delivered from the hot water connection unit 20. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
