Explanation of Calculation Methodology

Transmission losses: Heat losses through the building envelope (walls, roof, floor). Calculated according to the U-value and the temperature difference between inside and outside.

Ventilation losses: Heat losses through air exchange. Takes into account natural ventilation and mechanical exhaust systems.

Radiant heater advantage: Through direct heat radiation, the air temperature can be reduced by 2.5-4°C without loss of comfort. This leads to significant energy savings:

  • Reduced transmission losses through lower air temperature
  • Lower ventilation losses
  • Higher efficiency through targeted heating
  • Faster heating times

Calculation basis: The calculation is carried out according to proven engineering methods and takes into account the specific properties of radiant heating systems according to current technical literature.
