摘要： Disclosed is a boiler which is easily convertible from a normal type oil boiler to a condensing type oil boiler or vice versa thereby reducing manufacturing costs for the boiler. A size and a weight of the boiler are reduced by vertically installing a latent heat exchanger in an outer housing of the boiler together with a combustion chamber and a main heat exchanger. The boiler includes a combustion chamber, a heat exchange section, and an outer housing. Coupling holes are formed in the outer housing, a circulation chamber is formed at a lower portion of the outer housing, a burner is provided at an upper portion of the combustion chamber so as to generate heat in a downward direction thereof, the combustion chamber is vertically installed in one of the coupling holes, and a lower portion of the combustion chamber is communicated with the circulation chamber. The heat exchange section includes first and second heat exchangers and is vertically installed in the outer housing adjacent to the combustion chamber. An upper portion of the heat exchange section is coupled to one of the coupling holes and a lower portion of the heat exchange section is communicated with the circulation chamber. A funnel is provided at an upper portion of the outer housing so as to discharge an exhaust gas derived from combustion of the fuel in the combustion chamber, and a noise-absorbing container is provided at the upper portion of the outer housing so as to connect the funnel with the outer housing.
