PROBLEM TO BE SOLVED: To provide a radiator of a hot-water heater, which can be used also as a towel-hanger, and has an improved heating efficiency, and installed in a short time in a simple installation work without producing as far as possible a size error in the distance between a hot-water supply-pipe and a hot-water return pipe. SOLUTION: The radiator 1 of a hot-water heater is equipped with main path-pipes 2 and 3 laid vertically along a room wall W, and a plurality of heat conductive sub-path-pipes 9 laid across the main path-pipes. Hot water is supplied in circulation to the sub-path-pipes through the main path-pipes from heat-source equipment. A hot water inlet port 12A and an outlet port 12B are provided parallel closely to each other in an inlet-outlet pipe 12, which is provided under the sub-path-pipes. A stopcock 13 is provided between the inlet and outlet parts in the inlet-outlet pipe. A pipe connector 16 is provided through joints 14 and 15 to the inlet and outlet ports, and an inlet path 16C and an outlet path 16D are integrally provided in the connector 16.
