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

The pump’s post-run time is set to 5 minutes.
Measured at the sleeve where the return and supply sensors are located.
In my opinion, this should not happen during standby, or at least not be this high. And this is actually low. I have seen a difference of 8°C (14°F) between supply and return during standby before.

Is the difference the same on the manifold (HKV)? Return and supply temperatures at the upper floor manifold (HKV) are both 24.6°C (76.3°F) without deviation. At the heat pump, the return temperature is steady at 22.5°C (72.5°F) and the supply temperature is 24.2°C (75.6°F).

Here, have a look. The handwritten notes show the measured return temperature at the heating circuit distributor (HKV) on the ground floor from January 9th at 11 a.m., when the temperature differential really escalated. At the HKV, the return temperature is somewhere between 28-31°C (82-88°F). The heat pump sensor shows a value of about 25°C (77°F).
