Now that we know the primary return temperature, we can calculate the primary flow.
In the example above, the primary return temperature is calculated and results in 28°C. The primary flow is also calculated and results in 0.58 m3/h
step 5
The primary power and primary diversity factor are not impacted by regime changing base circuits, this is actually obvious :

system equation at secondary side
system equation at primary side
heat exchanger equation in between :
