Abstract

PURPOSE:To enable supply of a supply feed for heating through a supply conduit running to an expansion tank for heating water, by a method wherein a vacuum breaker is mounted to the feed water pipe of a hot water heat exchanger, drain of the vacuum breaker is utilized for supply of heating water. CONSTITUTION:Heating water is heated by a heat exchanger 6 for heating with the aid of a circulating pump 8, and is circulated, in order, through a heating outbound pipe 6a, radiator heating return pipe 6b, and an expansion tank 7. Meanwhile, with a hot water feed faucet 12 opened, a hot water feed circuit A feeds hot water, heated by a heat exchanger 1 for feeding hot water. In a vacuum breaker 10 mounted to the heat exchanger 1 for feeding hot water, when the hot water feed faucet 12 is opened and closed, slight water hammer occurs due to a feed water pressure, and pulsation phenomenon of a water pressure occurs. In this case, several drain drops flow out from the vacuum breaker 10. The drain drops are guided to a supply water conduit 5, and drain is supplied to the expansion tank 7. Each time the hot water feed faucet 12 is closed, several drain drops are supplied to the expansion tank 7, and through control of a supply water valve 4, the man hour required for supply of drain to the expansion tank 7 is saved.
