<p>PURPOSE:To improve stability of the output hot water temperature by estimating consumption calorific value from when outputting of hot water is started in outputting of hot water and by performing start and stop of combustion according to the ratio of the integrated consumption calorific value to the can body thermal capacity in a can body in a storage-type hot water supplying machine wherein hot water can be reserved to the fixed temperature. CONSTITUTION:In a storage-type hot water machine A, a heat exchanger (can body) serving as also a hot water storage tank 2 is arranged on the upper part in a casing 1, and a combustion burner 3 is provided on the lower part. The hot water supplying operation of the hot water supplying machine A is controlled by a control unit 5, and in this case, output signals of a temperature sensor 4, an input water temperature sensor 10, a water volume sensor 9 and an output hot water temperature sensor 12 provided on a tank main body 2a of the can body 2 are input together with the set temperature input from a control panel 14 into the control unit 5. And the consumption calorific value from when outputting of hot water is started is integrated in outputting of hot water. Moreover, the ratio of the integrated consumption calorific value to the can body thermal capacity to be accumulated in the can body 2 is found, and the combustion by the combustion burner 3 is started and stopped according to this ratio, so as to perform the temperature control of the can body 2.</p> |
