Hello!
I'll start.
Heated area 200m2 (2,153 sq ft)
KfW 55 standard
Mechanical ventilation with heat recovery
Current outdoor temperature 6°C (43°F)
Heating energy consumption including hot water 35 kWh
Electricity consumption 9 kWh
COP 3.88

Middle Franconia in Bavaria, 450m (1,480 feet) above sea level. The standard heating degree days (Norm-AT) are -13.2.
That’s impressive. How well the heat pump is performing. I’m almost jealous!

@halmi I have now set the actuators to manual and opened them. This means they should currently be without power. How much improvement can the balancing between the supply and return in the heating circuit valve provide when measured with an IR thermometer? Current heating consumption today so far is 12 kWh.

The purpose of the balancing is to identify short circuits, meaning circuits that heat up too quickly. It also applies to rooms that have multiple circuits with different lengths.

As @tomtom79 writes, I would make sure that you don’t have any circuits where the return temperature is significantly higher than the others. Ideally, the temperatures should be very similar.

The return temperature should not rise too much during the first 15 minutes.

That does not happen; rather, the opposite is true.
