The purpose of the present invention is to provide a boiler including a bypass valve having an integrated drain cork so as to reduce the number of components and simplify a piping structure by integrating the bypass valve with a drain cork. In order to achieve the above described purpose, the boiler according to the present invention comprises: an integrally formed connection body (200) including an inlet pipe (210) connected to a heating supply pipe (110) so that heating water can flow therein, an outlet pipe (220) intercommunicating with the inlet pipe (210) and connected to a heating water return pipe (120), and a drain pipe (230) intercommunicating with the inlet pipe (210) and the outlet pipe (220) and discharging the water in the boiler to the outside; and a valve module (300) consisting of a bypass valve part (310) disposed between the inlet pipe (210) and the outlet pipe (220) to allow the water in the heating supply pipe to bypass to the heating water return pipe when the pressure in the heating supply pipe is at or above a predetermined pressure, and a drain cork part (320) inserted into the drain pipe (230) while the drain cork unit is coupled to the bypass valve part (310) so as to open or close the drain pipe (230). |
