PURPOSE: A heating device with an improved heat exchanging structure is provided to improve heat exchanging efficiency by performing heat-exchanging through a second vent pipe. CONSTITUTION: A heating device(1000) with an improved heat exchanging structure comprises multiple first and second vent pipes(240,240'). The first vent pipes are connected to the inner side of a heater body receiving part(200) and are protruded from the heating device through first and second flange units(210,220), a second casket, and a heater body flange unit(130). The second vent pipes are connected to the bottom of the heater body receiving part and are protruded to the outside the heating device through the first and second flange units, the second casket, and the heater body flange unit. |
