You don’t post any logos, you do have USB access, right?
Yes, I did already. But there was nothing derivable from it. I also don’t know if it’s due to the heating or the building envelope. Sometimes I wonder how quickly the supply and return temperature drops when the heating hasn’t been running for a few hours.
850kwh in January for 200m2. Just under 30kwh per day without household electricity. Unfortunately, my heat pump is still not running optimally.
How high was the heat quantity? That doesn't sound so bad. For me, it was 685 kWh heating electricity for an astonishingly high 2740 kWh heat quantity (=COP 4.0), also around 200m2. What are your experiences, did you actually have higher heating costs in the first year in solid construction due to construction moisture, or did that remain relatively the same in the following years? I had actually expected a somewhat lower heat demand for the KfW55 house.

January has also been the worst for us since moving in.
Constantly cold, but mostly just below 0 where an air-to-water heat pump is least efficient. Plus only 4 sunny days...
We almost used 700 kWh of electricity. Last January it was 500.
