ABSTRACT:
As a heat exchanger for a hot-water storage type gas boiler, the present invention provides an easily assembled stacked-up type heat exchanger eliminating the installation of a separate hot-water pipe so that the thermal efficiency of the heat exchanger can be improved and the size thereof can be reduced. The stacked-up type heat exchanger comprises a bottom plate including one or more combustion gas flues for carrying combustion gas from a burner, a return heating-water outlet for collecting and delivering heating-water, and a cold-water inlet; a first plate disposed over the bottomplate; fourth plate disposed over the first plate; and a top plate disposed over the fourth plate.
