At the time of starting a hot water discharge operation, a controller determines whether the first operation was made after the power source is switched on in S, and the controller determines whether 5 minutes have passed after the previous operation in S. When the first operation was not made or 5 minutes have lapsed after the last operation, the controller determines whether a difference between a detected temperature acquired by a thermistor and a preset temperature is more than 10&#xb0; C. in S. When a temperature difference is more than 10&#xb0; C., a water flow rate servo is set at a position where a flow rate of flowing water is reduced from a determined flow rate by a predetermined amount in S, and the controller performs a temperature control of discharged hot water in S

Water heater

A water healer including a controller that, in a non-operation state, determines whether the first operation was made after a power source is switched on in S, and determines whether 5 minutes has passed after finishing the last operation in S. When the first operation was not made or 5 minutes have lapsed after the last operation, the controller determines whether a difference between a detected temperature acquired by a thermistor and a preset temperature is more than 10&#xb0; C. in S. When a temperature difference is more than 10&#xb0; C., a water flow rate servo is made to stand by at a position with a flow rate of flowing water reduced to less than a determined flow rate by a predetermined amount in S. When a hot water faucet is opened in this standing by state, a temperature control of discharged hot water at the time of starting of an operation is performed with the reduced flow rate of flowing water.
