<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply system capable of positively stabilizing a flow rate of tap water, solar water, or mixed water sent from an electric mixing valve in regard to a combustion state of a burner, and capable of efficiently carrying out hot water supply. <P>SOLUTION: A flow rate sensor 7 is set with a fire extinguishing flow rate, a pressurization pump operation flow rate less than the fire extinguishing flow rate, and a flow rate more than the fire extinguishing flow rate, allowing ignition of the burner. In a controller 33, when it is detected that a flow rate has become the pressurization pump operation flow rate or more, less than the fire extinguishing flow rate, the solar water 11 is pressurized by a pressurization pump 20. By this, different from when driving the pressurization pump 20 to pressurize the solar water 11 after carrying out combustion operation of the burner 34, a flow rate of the mixed water 32 from the electric mixing valve 31 is stabilized by the solar water 11 vigorously sent by the pressurization pump 20. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
