A firewood boiler is provided to easily install lagging on an exterior of a housing by installing pipes on a pipe hiding groove not to expose the pipes outside the firewood boiler. A firewood boiler includes a firewood inlet(20) located on a front plane of a housing(10). A space between the housing, a vertical combustion chamber(30), a flame detour(32), a horizontal combustion chamber(40), a connection pipe(42), and a heat transfer box(44) is filled with water heated by the combustion of firewood. The horizontal combustion chamber is connected to the firewood inlet for flowing the flame or the energy of the firewood to exchange energy with water outside the horizontal combustion chamber. The vertical combustion chamber is formed on a lower part of the horizontal combustion chamber. The flame detour is formed on the side of the vertical combustion chamber for flowing the flame generated from the vertical combustion chamber. The connection pipe is located on an upper part of the horizontal combustion chamber in an opposite side of the firewood inlet. The heat transfer box is connected to the connection pipe. A chimney(50) is connected to the heat transfer box for exhausting smoke. A pipe hiding unit(12) is formed by being dug at a rear surface or a side surface of the housing from a top portion to a bottom portion by a predetermined depth with reference to a place where the firewood is positioned. |
