PURPOSE:To improve an efficiency of heat accumulation by a method wherein a heating heat exchanger is laterally passed through within a container of the boiler and an outer shell cylinder is overlapped on the heat exchanger. CONSTITUTION:Within a container 1 of the heating boiler is laterally passed at its upper part a heat exchanger 4 which is composed of baffle plates 6 arranged within the cylinder 5 and the burner 7 closely adjacent thereto. Discharging pipe 8 is connected to the cylinder. At the outer circumference of the heat exchanger 4 is covered an outer cylinder 9 so as to form a heat exchanging unit 10 for heating operation and then a heating pipe 11 is connected thereto. |
