Hello again
We tested s4 22 with 10 senzors on puffer and software how much power in kw,puffer gets. With 2 years old buche wood, Flue gas was set to 190C lambda 9%. Kst was around 35% ventilator was around 40%.
So resoults was that boiler output was 22kw. So that we realized that if the ventilator works under 50% that dosent mean that the boiler works at half power.
