Abstract: PURPOSE: To prevent a breakdown of circuit parts and an extra feeding of hot water by providing a ball tap housed in a cistern tank of the hot water supply device for air warming with a safety device which can release an expanded water within a hot water supply circuit which is sealed up into the tank.  
     CONSTITUTION: The ball tap 8 within the cistern tank 2 of the hot water supply device for the air warming purpose is provided with the safety valve 19. When the water level in the tank 2 reaches a predetermined level, a valve seat 16 of the ball tap 8 closes so as to put the hot water supply circuits 12 and 13 in a sealed condition. Next, when a pump 2 of a hot water machine 1 is driven to warm the water in a hot water supply coil 3, the water also expands increasing the pressure within the hot water supply circuits 12 and 13. If the pressure rises above a predetermined value of the safety valve 19, the safety valve 19 begins to operate so that the expanded water is discharged into the tank 2, thereby protecting the respective parts within the circuits. Further, since the discharged water is poured into the tank 2, any extra hot water supply can be eliminated.
