Steel panel radiator with flat front panel with fine horizontal grooves and universal connection

Model RADIK LINE VKM8 is a panel radiator with flat front panel with fine grooves (version LINE) and at the same time it is in version VENTIL KOMPAKT. This design allows bottom middle or bottom right connection of the radiator to the heating system with forced circulation. Two upper and two lower hangers are welded to the back side of the radiator, the radiators with length of 1800 mm and more are equipped with six welded hangers.

In case of two-pipe heating system it is necessary to calculate the correct level of valve presetting and specify this in the project documentation to ensure a proper function of the heating system. This must be kept by the installer during installation of the heating system.

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)
