Design radiators with vertically aligned profiles, side connection and a mirror

Design radiator KORATHERM REFLEX represents a modern design combined with an effective way of heat emission to the heated room. Its front panel produces a high share of radiant heat thus evoking a feeling of thermal comfort. Thanks to its design it is not only pleasant but also a highly practical complement to any reception area and entrance halls in both residential and public buildings.

It is designed for two-pipe pressurized heating systems, the heating profiles are vertically aligned. There is a mirror (size 220 x 1800 mm) attached to the heating surface, it is glued to a strip of zinc-coated metal sheet. The connection to the heating system is side from the top down with a constant connecting pitch of 1750 mm (example of product code K10R). It is equipped with 4 side connections with inside thread G½, an air vent and a blanking plug with G½ thread. It is delivered in types 10 and 20 with side panels.

KORADO now offers also towel hangers and pegs which extend the practical use of KORATHERM design radiators.

Heat output [W]



  • t1 - input water temperature
  • t2 - output water temperature
  • ti - desired room temperature

For the conversion of heat outputs change the default values.

Heat output calculated to ∆T= 50; (t1/t2/ti = for 75/65/20 °C)
