PURPOSE:To enable confirmation of ignition and hot water being supplied to a hot water supplying boiler without fail, by detecting the heightened temperature in a thermistor installed in a pipeline of feed hot water, and by transmitting a detected value to a telephone through a tele-control system as an ignition signal. CONSTITUTION:When a person calls his own telephone at home from a telephone 11 out of home in order to bring a hot water supplying boiler 1 into operation, a control signal is transmitted to an interface 7 through an HA tower 8, and a solenoid-operated valve 2 for water is opened. Then water flows through the hot water supplying boiler 1 and through a feed hot water pipeline 4, and the gas hot water supplying boiler 1 starts an igniting action. A thermistor 5 functions to detect the temperature in the water flowing through the feed hot water pipeline 4. After ignition when the temperature in water rises, the resistance in the thermistor 5 is lowered, and a monitor signal is transmitted to the HA tower 8 by the thermistor 5 when the temperature reaches a set value. The actual supplying state of feed hot water can be monitored through a tele-control system by installing a thermistor 5 in a feed hot water pipeline 4, by detecting the temperature in feed water, and by confirming ignition in a hot water supplying boiler 1 when the temperature in hot water rises to a set temperature. |
