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)
