PURPOSE:To contrive to improve durability, to prevent dew condensation from developing and to improve lighting property by a constitution wherein cold or hot water is supplied to heat radiating pipes, the whole surface of each of which is transparent or on a part of said transparent surface of which radiant heat reflecting film is formed, in a radiator for radiant heating or the like. CONSTITUTION:A plurality of cylindrical heat radiating pipes, the whole surface of each of which is transparent, are connected to manifolds 2 and 3 in order to dissipate or absorb radiant heat by being supplied hot or cold water thereto. In this case, in accordance with the installation site and conditions of a radiator A, radiant heat reflecting substance 4 is coated or pasted on one side of the radiator A and the side facing to things to be heated or cooled is left transparent. Due to the constitution as mentioned above, dew condensation is prevented from developing and the durability of the radiator can be improved without disturbing lighting.
