Abstract
A water heater equipped with a leakage detecting device is provided. A flow control valve is disposed at an inlet and controls the flow rate of water flowing into the water heater. A leakage detecting device detects when water which has flowed in the water heater leaks out through pipes in the water heater due to burst of the pipes and is filled at or more than a predetermined level from the floor of a water heater case, and transmits a signal to a controller. A case protects parts in the water heater by shielding the parts from the outside. The controller controls a series of combustion processes and operation of the water heater, and closes the flow control valve, when a leakage detection signal is transmitted from the leakage detecting device.
