Addendum:
Of this, 457 kWh in January were caused by the quickly activated heating rod, as I only started optimizing then. Annual performance factor: 3.15

The values set by the heating engineer were predictably not so good. He apparently had not installed a NIBE before either. But we had no influence.

Minimum temperatures were approximately as follows:

Good value, but approx. 30 years payback period compared to [Luft-Wasser-Wärmepumpe] is still not economical despite subsidies. Therefore, [Sole] remains something for enthusiasts, would have liked to do it too because great technology.
