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

And what flow rate does the efficiency pump show you?
I just looked at about 10 different .dtas from your heat pump model, and nobody really has such a high temperature difference; your supply temperature is sometimes almost 40°C (104°F)... It can’t display that. Yes, I know, I have noticed that too.

If it has been heating continuously for 7 hours, it can’t be that often.

If it has been heating continuously for 7 hours, it can’t be that often. The last heating cycle on the right is "normal"
- no divergence during standby
- the supply and return curves come back together completely after the heating operation ends.
Everything else to the left is unusual and unnecessarily prolongs the heating operation, shortens the intervals between cycles, and makes the operation "expensive."
Basically, the blue and red curves must fully match except during heating operation and hot water production.

At the marked point, was the heating element active? I can’t clearly tell from the graph. In the AI/Novelan heat pumps, didn’t you suspect a defective return sensor?
