PURPOSE:To permit the automatic pouring of water into a tank, by providing a water pouring solenoid valve, opened for a given time in interlocking with a water level switch detecting the reduction of the water level in the tank. CONSTITUTION:A water pouring solenoid valve 9 is opened for a given time in interlocking with a water level switch 1. In the constitution of the system of a water pouring device for a tank, hot-water flows as shown by arrow signs in a diagram to function as room heating. When the amount of the hot-water is reduced by evaporation, the water level switch 1 detects the reduction of a water level in the tank 2 and the solenoid water pouring valve 9 is opened in interlocking with the detection of the water level switch 1, whereby water flows from water supplying side through a water pouring pipe 10 and is poured automatically into the tank 2. The amount of water, flowing through the water pouring pipe 10, is determined by the passageway resistance of the water pouring pipe 10 and the opening time of the water pouring solenoid valve 9 in accordance with the capacity of the tank 2.
