The boiler includes a combustion chamber, a heat storage tank, a heat exchanger, a flue member, and an air inflow part. The flue member includes a lower connection part which is connected to the upper part of the combustion chamber. A first connection part has one end connected to the lower connection part and the other end extended in a first direction different from the lower connection part. A second connection part has one end connected to a part adjacent to the lower connection part of the first connection part and the other end extended in a second direction different from the first direction. A first flue has one end connected to a part adjacent to the first connection part of the second connection and the other end for discharging the rest of smoke to an upper surface direction. An upper flue surrounds the first flue and has a second flue arranged on the heat storage tank. The air inflow part has one end connected to the outside and the other end connected to the bottom of the combustion chamber. Therefore, a fire due to the overheat of a boiler can be prevented. |
