Consumed about 28 kWh in the last 24 hours. Currently it's just over -10, average temperature -7.5.
At the AT I have 32 degrees or 28 degrees. So my heating curve seems to be a bit steeper. Let's see how the temperatures look tomorrow morning. I find your consumption really good.
Phew, you have a modulating one! Then it would make sense to increase the runtime, first set the hysteresis back to 2 degrees, and then lower the heating curve, so it should run longer.
