A storage type boiler heat exchanging structure for preventing condensation is provided to increase durability by preventing a corrosion of the heat exchanging structure due to the condensation in case that the heat exchanging structure is manufactured by using a conventional material. In a storage type boiler heat exchanging structure for preventing condensation, a heating supply outlet is installed on a top of a boiler(10). A heating water inlet is prepared at a bottom of the heating supply outlet. An inner pipe(30) is installed inside of a water pipe unit(40) of the boiler and extended in a spiral shape from the heating water inlet. The extended inner pipe is coupled to a reentrance port(24) of a bottom stage of the boiler by being connected to an extension pipe unit extended through an reexit(26) passing through a boiler sidewall. The inner pipe is constructed inside of the water pipe unit of the boiler by being separated at a predetermined distance from the boiler sidewall. The extension pipe unit has a construction to prevent heat of the hot water from being discharged to the outside thereof. |
