  • Said shaped fins 36 are preferably welded to a sheet 34 or 35, in particular to the front sheet 34.
  • each shaped fin 36 has two flat portions 37, having a width substantially equivalent to the thickness of the support element 3 in such a way as to have the sides in contact with said sheets 34 and 35, and has a connection band 38 between said flat portions 37 to form a cavity for the passage of the second duct 19.
  • the heat transfer fluid stipulates only inside a pipe having a circular section 9 which is more highly performing in terms of resistance to pressures, while regarding the surface temperatures the lower content of heat transfer fluid together with an indirect and degraded heat transfer between the second duct 19, the shaped portions 36 and the sheets 34 and 35 make them always adapted to dry/heat the hand towels without however exceeding the maximum values even when the delivery temperatures are high, obviously without compromising the temperatures that can be reached in the fixed body 2 of the radiator 1.
  • an electric-powered thermal heating can be provided.
  • Such system of thermal resistances is connected to a power unit 42, preferably arranged in the fixed body 2, and controlled by a control unit, in particular a chronothermostat, preferably a radio frequency chronothermostat.
  • the radiator could be of the mixed type and provide both electric and hydraulic heating means.
