Steel panel radiator with left bottom connection for nursery schools

The model RADIK MATERNELLE VKL is a steel panel radiator in the VENTIL KOMPAKT version allowing a left bottom connection to the heating system with forced circulation of hot water. The special design of the concept MATERNELLE radiators prevents entry of hot water in the front panel. This ensures a safe surface temperature. Two upper and two lower hangers are welded on the rear side of the radiator. Radiators 1800 mm and longer have 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)
