Heating curve steepness tells us, what temperature is required for the heating bodies by
a determined outdoor temperature. The steepness setting depends on the type of heating
system (floor, wall, radiator, convector heating) and insulation of the building.
HEAT CURVE
If you have enough data, you can determine the heating curve steepness with a calcula-
tion, otherwise from experience, based from the evaluation of heating system dimension-
ing and building insulation.
The steepness is set correct, if the room temperature remains stable, even by large out-
door temperature changes.
Until the outdoor temperature remains above + 5 °C, you can adjust the room tempera-
ture with changing day or night temperature or with parallel shift of the heating curve.
