<P>PROBLEM TO BE SOLVED: To provide a hot-water heating system that more reliably produces an effect of reducing the time to start heating in a heating terminal by a heating operation in a rapid heating mode. <P>SOLUTION: When starting a heating operation, a floor heating controller 54 controls a heating quantity of a burner 15, in a 'first rapid heating mode', to obtain 80°C detection temperature of a heating high-temperature thermistor 18. When a detection temperature of a heating low-temperature thermistor 20 is 70°C or lower after carrying out the control thereof, the controller executes a heating operation in a 'second rapid heating mode' for increasing the heating quantity of the burner 15 to obtain 70°C detection temperature of the heating low-temperature thermistor 20. After finishing the heating operation in the 'second rapid heating mode', the controller switches to a heating operation in a 'normal heating mode' to control the heating quantity of the burner 15 to obtain 60°C detection temperature of the heating low-temperature thermistor 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
