Abstract
PURPOSE: To prevent the flow-out of unnecessary water by arranging a freezing preventing valve which detects the outside air temperature and opens on a hot water feeding passage and constituting said valve so as to detect the temperature of water which flows out from said valve and to perform restoration.
CONSTITUTION: By a diaphragm 13 at the water pressure operation part 14' of a water current detector 10 arranged on the water feeding passage 11 to a heat exchanger 2, a switch 15 is opened and closed to control a burner 16, and a freezing preventing valve 4 is arranged in the water passage 5 branched from a hot water feeding passage 3 having a hot water feeding cock 9. With said freezing preventing valve 4, a valve body 6 is removed by an operation part 8 consisting of thermo expansion body, and the water passage 5 is opened and closed.
