<p>PROBLEM TO BE SOLVED: To provide a hot-water supply apparatus which can find the quantity of fuel burned by means of a burner per unit hour, can appropriately control the residual quantity of fuel in an oil tank, and can be improved in easiness in construction and reduced in maintenance cost. SOLUTION: This hot-water supply apparatus is provided with a burner which heats water in a heat exchanger by burning the fuel supplied from the oil tank, a control means which computes the quantity of the fuel burned by means of the burner per unit hour and, at the same time, controls the burner based on the computed quantity, and an information displaying means which displays the information on the quantity computed by means of the control means. The control means is provided with a computing means which computes, for example, the quantity of the fuel burned by means of the burner per unit hour and an integrating means which integrates the quantity computed by means of the computing means. In addition, the control means compares the supplied quantity of the fuel inputted from an inputting means and stored in a storing means with the integrated value of the quantity of the fuel integrated by means of the integrating means and outputs the results of comparison to the information displaying means.</p> |
