PURPOSE: A heat exchanger for condensed gas firing boiler is provided to simplify the structure of the heat exchanger for making the boiler product be compact and reducing manufacturing cost as well as to improve heat transfer efficiency by permitting exhaust gas to directly contact with the heat exchanger. CONSTITUTION: A heat exchanger for condensed gas firing boiler is constituted by mounting a heat exchanger(100) in an exhaust chamber through which exhaust gas is vertically discharged. The heat exchanger(100) is provided with a plurality of radiating plates stacked with a narrow width, a honeycomb type hot water supply channel, and an exhaust channel. The hot water supply channel is connected to a heating water supply and discharge members(104, 105). The exhaust channel is connected to an exhaust opening(114). Accordingly, since the boiler heats the heating water recovered from heating piping, the consumption amount of gas is minimized. Also, since the structure of the boiler can be simplified, product can be compact and manufacturing cost can be reduced.
