Steel panel radiator with flat front panel and bottom middle connection

RADIK PLAN VKM is a steel panel radiator which enables a bottom middle connection to the pressurized heating system. There are two upper and two lower hangers welded at the back of the radiator. Radiators in length 1800 mm long and more have six hangers. RADIK PLAN VKM radiators are supplied with an air vent, two blanking plugs and a valve with a plastic cap.

Pressure Loss

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)
