Claims

[Scope of utility model registration request]

In a hot water device equipped with an electric heater, a sensor for detecting the temperature of hot water heated by the heater, a means for setting a target water temperature according to a user's adjustment operation, and a means for setting a control water temperature lower than the target water temperature by a predetermined value. and a set water temperature switching means that selectively switches between the target water temperature set by both of the setting means and the control water temperature, and compares the set water temperature given by the set water temperature switching means with the water temperature detected by the water temperature sensor. means, an energizing circuit that turns on and off energization to the heater according to a signal from the comparison means, an on-timer that detects when energization to the heater continues for more than a certain period of time, and an on timer that detects when energization to the heater is interrupted for more than a certain period of time. The set water temperature switching means switches the set water temperature from the target water temperature to the control water temperature in response to a signal from the on timer, and thereafter switches the set water temperature from the control water temperature in response to a signal from the off timer. A heating control device for a hot water system, characterized by returning the water temperature to a target temperature.
