HEATING CURVE
The heating curve slope provides information about the required temperature of heating
devices at certain outdoor temperature. The value of the slope depends mostly on the type
of the heating system (oor, wall, radiator, convection heating) and the thermal insulation of
the building.
Determining the slope of the heating curve
The slope of the heating curve can be calculated if there is enough data available, other-
wise through experience based on the estimate of the heating system dimensioning and
thermal insulation of the building.
The slope of the heating curve is selected correctly if the room temperature remains intact
even at major changes of the outdoor temperature.
As long as the outdoor temperatures are above +5°C, the room temperature can be regu-
lated with the setup change of the day or night temperature or parallel shift of the heating
