Patent ID: 8281751

Claim:
A hot water apparatus comprising a main body connected to a water distribution device via plumbing, a remote controller for remotely controlling the main body of the hot water apparatus, and a deviation value determining element, the main body of the hot water apparatus comprising a control device configured to control a temperature of outflowing hot water, which is a temperature of the hot water outflowing from the main body of the hot water apparatus to the plumbing; the remote controller comprising: a setting element configured to set a requested value of the temperature of outflowing hot water; and a correction-data setting element configured to set correction data as a deviation level; and the deviation value determining element is configured to determine a deviation value based on the deviation level and the requested value, wherein, when the correction data is set by an operation of the correction-data setting element and the deviation value is determined by the deviation value determining element, the control device is configured to perform processing for correcting the temperature of the outflowing hot water so that the temperature of the outflowing hot water is controlled to a target temperature which is obtained by changing the requested value by the deviation value, and wherein, when the requested value is less than or equal to a predetermined temperature, the deviation value determining element is configured to determine the deviation value as a predetermined minimum deviation value, and the control device is configured to control the temperature of outflowinq hot water to the target temperature which is obtained by changing the requested value of the temperature of outflowinq hot water by the predetermined minimum deviation value.
