Summary:PURPOSE:To reduce noise by a method wherein an amount of gas to be burned in a second burner for an additional combustion is reduced in case that an amount of gas to be burned in a first burner exceeds a predetermined amount when a simultaneous combustion for a hot water feeding and an additional combustion are carried out and at the same time a second blower is controlled. CONSTITUTION:When a hot water feeding first burner 2 and an additional combustion second burner 9 are simultaneously burned, a control device 17 may send a control signal to a second gas control device 10 and a second blower 16 as an amount of gas to be supplied to the first burner 2 is increased more than a predetermined amount so as to control an amount of gas and an amount of air to be supplied to the second burner 9 to an amount half of that amount when the second burner 9 is burned alone. Accordingly, it is possible to reduce combustion noise generated at the second burner 9 and a beat sound generated at the second blower 12 and further as a whole it is possible to decrease a noise of an equipment.
