CONTROL METHOD OF WARM WATER TAPPING FOR GAS BOILER

摘要

PURPOSE: A control method of the warm water tapping for a gas boiler is provided to promptly tap the warm water heat-exchanged by slowly reducing the circulating pump of a working boiler if a flow switch for sensing the use of the warm water is turned on. CONSTITUTION: The control method of a gas boiler is formed by the steps of:slowly reducing a circulating pump(20) of a working boiler if a flow switch(10) for sensing the use of the warm water is turned on; keeping the warming action by rapidly revolving the circulating pump(20) if the flow switch(10) is returned to the off state in a specific time; and firing a burner again to feed the warm water after extinguishing the burner by stopping the circulating pump(20) and by closing a gas valve(40) if the on state of the flow switch(10) is maintained during a certain time.
