Abstract: PURPOSE: A condensing boiler is provided to reduce heat loss because an upper tank part is arranged on the upper side of heat exchange pipes. CONSTITUTION: A condensing boiler(100) comprises a burner part(110), first and second heat exchange pipes(120,130), a partition wall(140), lower and upper tank parts(150,160). The burner part discharges combustion gas to the underside. The first heat exchange pipes surround the burner part at an interval. The second heat exchange pipes surround the first heat exchange pipes at an interval. The flow paths of hot water are vertically formed in the first and second heat exchange pipes, respectively. The first and second heat exchange pipes have independent internal flow channels and are inserted into through holes of the partition wall. The partition wall divides the first and second heat exchange pipes into an upper sensible heat exchange part(103) and a lower latent heat exchange unit(104). The lower part and upper tank parts are respectively coupled to the bottom and top of the first and second heat exchange pipes. The lower tank part distributes external heating water to the first and second heat exchange pipes. The upper tank part discharges heating water from the first and second heat exchange pipes to outside.
