PURPOSE: A pipeline arrangement is provided to prevent aquatic plants from growing in the pipeline by preventing the temperature rise of the expansion tank. CONSTITUTION: A pipeline arrangement comprises a hot water boiler(3); a circulation pump(4) connected to the hot water boiler; the first main pipe(5) connected to the circulation pump; a radiation pipe branched off from the first main pipe; the second main pipe(9) connected between the radiation pipe and the hot water boiler; and an expansion tank(10) arranged on the second main pipe. A connection pipe(12) for interconnecting the second main pipe and the expansion tank has a certain part which is connected to the expansion tank in such a manner that the certain part of the connection pipe is lower than the second main pipe.
