Slope

Adjust the 'Slope' of the heat curve, if required.
The heat curve slope depends on the heating system and area specific design
parameters.
Example I
Design parameter:
Designed outdoor temperature (T
Designed flow temperature (T
Designed room temperature (T
For designed flow temperature higher than 40 °C, the heat curve slope (S) can be
calculated as:
T
flow
S =
2.5 x T
room
80 - 25
S =
2.5 x 20 - (- 12) - 30
S ≈ 1.7
Example II
Design parameter:
Designed outdoor temperature (T
Designed flow temperature (T
Designed room temperature (T
For designed flow temperatures lower than 40 °C, the heat curve slope (S) can be
calculated as:
S =
1.3 (2.5 x T
S =
1.3 (2.5 x 21 - (- 20) - 30)
S ≈ 0.3
For quick setting, the graph can be used. The graph is intended for a T
design data from example I is used, the slope will be approx. 1.7.
