<p>PROBLEM TO BE SOLVED: To prevent a water level defect from being caused at the time of hot water filling operation by inhibiting a storage means from being read and written during the operation of equipment. SOLUTION: With a hot water filling switch 23 ON after desired temperature and a desired water level are set by a temperature setting means 9 and a water level setting means 10, an on/off valve 15 provided to bath piping is opened and a controller calculates a necessary combustion quantity from the temperature set by the temperature setting means 9, and temperature filling water temperature detected by a filling temperature sensor 18 provided to feed water pipe, and a flow rate detected by a flow rate sensor 17 and fuel is supplied to a burner 11, so that combustion is started. When the water level detected by a water level sensor 16 reaches the set water level, the on/off valve 15 is closed to stop the combustion, thus ending the hot water filling operation. After the hot water filling operation, the signal of a write request is sent to a storage means 33. At this time, whether or not the combustion device is in an operation standby state is monitored and when not, neither a reading process nor a writing process of the storage means 33 is performed.</p> |
