A composite boiler is provided to reduce the operating cost by simultaneously or selectively performing bottom heating and space heating by using one boiler. A composite boiler comprises a casing(100) and a twin heat exchange section(200). A hot water tank is coupled with the upper portion of the twin heat exchange section. An air suction port(240) is coupled with one side of the twin heat exchange section and an air discharge port(250) of the other side of the twin heat exchange section. The casing has a combustion gas discharge port(130) and an air suction hole therein. The twin heat exchange section includes a hot water heat exchange port and an air heat exchange port, which are coupled between support plates(210') having a plurality of support holes(211'). Hot water pipes(221) are horizontally arranged in a zigzag manner at the lower portion between the support plates. |
