Abstract

PURPOSE:To prevent the risk due to postboiling, by making it unnecessary to appoint the set temperature of a thermostat at a high value to prevent the erroneous operation associated with the postboiling. CONSTITUTION:A hot water supply pipe 4 of a tank 1 having a heater 2 is provided with a differential pressure apparatus 5 and a manual cock 6, and a bypass pipe 7 that bypasses them is provided with a slenoid valve 8. When the cock 6 is opened to supply hot water, the differential pressure apparatus 5 closes a switch 9 to allow an electric current to pass through the heater 2 and at the same time to allow an electric current to pass through a timer 11, which closes a contact 12 to allow an electric current to pass through a coil 13 to open the solenoid valve 8. After the hot water supply, when the cock 6 is closed, the switch 9 is opened, and the electric current to the heater 2 is cut. After a prescribed period has passed after the cut of the electric current to the heater 2, the timer 11 opens the contact 12 to close the solenoid valve 8.
