Steel panel radiator for combined heating

RADIK COMBI VK is a panel radiator in VENTIL KOMPAKT design allowing a right bottom connection to the pressurized heating system.

RADIK COMBI VK is designed for a combined installation with an electric heating element. This combination makes this panel radiator suitable for combined heating (hot water - electricity) which can be used independently from the operation of the heating system. On the part of the electric installation the electric heating element does not require any special arrangements in the heated room. It is recommended to be installed together with the radiator.

There are two upper and two lower hangers welded at the back of the radiator. Blanking plugs, an air vent and a valve with a preset flow rate covered by a plastic cap are delivered as standard.

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)
