The nonlinear heat transmission is considered by the radiator exponent nH. The follow-
ing table gives an overview of the different types of heating systems normally used:
Heat transmission via… Radiator exponent nH
Underfloor heating system 1.05…1.1
Flat radiators 1.26…1.33
Radiators to DIN 4703 1.3
Convectors 1.25…1.45
