Abstract

PURPOSE:To prevent an interruption gap in operation when an ignition in one burner is changed over to an ignition in the other burner by a method wherein a controllable minimum capability of a first burner under a proportional control is made smaller than a maximum capability of a second burner under an intermittent ignition control. CONSTITUTION:A first burner 2 may vary a degree of opening of a proportinal valve 8 when a first solenoid valve 7 is opened and vary a heat amount by varying an amount of gas being supplied. The second burner 3 performs an intermittent ignition by repeating an opening or closing of a second solenoid valve 10 and can vary a heat amount in response to a ratio between a time when the flame is kept and a time when the flame is put out. Since the first burner 2 is constituted such that its minimum capability is lower than a heat amount obtained under a continuous combustion in the second burner 3, that is, the maximum capability of the second burner 3, it is possible to control the capability from minimum to maximum values without interruption in response to the required heat amount.

A gas instantaneous hot water supply device characterized in that when the temperature is within the range of 1 to 10, the control is performed by intermittent combustion control of the second burner.
