At 70 °C average boiler water temperature and cylinder storage temperature Tcyl = 60 °C.
The performance factor NL changes with the cylinder storage temperature Tcyl.
Standard values: Tcyl = 60 °C
→
1.0 × NL Tcyl = 55 °C
→
0.75 × NL Tcyl = 50 °C
→
0.55 × NL Tcyl = 45 °C

Calculation values for sizing the flue gas system to EN 13384.
Flue gas temperatures measured as gross values at 20 °C combustion air temperature.
The flue gas temperature at a return temperature of 30 °C is significant for the sizing of the flue gas system.
The flue gas temperature at a return temperature of 60 °C is used to determine the application range of flue pipes with max. permissible
operating temperatures.
