What flow temperatures are you currently running?

Since we never wear slippers or similar, you can clearly notice the difference whether a tile is 20° or 24°. It probably wouldn't matter to me, but my wife notices every degree I adjust on the heating. I once set it to 5° instead of 6° parallel displacement, and she noticed immediately.

Unfortunately, there is no intermediate step between 0.2 and 0.3 in steepness.

Correction

I of course meant between 0.1 and 0.2

Has any of you ever observed the behavior of the systems and the associated temperatures in the rooms over a longer period of time? These snapshots do not say anything at all. The flow temperature is constantly going up and down. That means it can have completely different values at the same outdoor temperatures and the same indoor temperatures in the same house.

These snapshots say absolutely nothing.

But they make it easier to compare d*ck size when it comes to heat pump and underfloor heating design ;) Appropriately, I think mine is not exactly the shortest...
Room temperatures everywhere around 21.5 - 22 °C.

Not at all, because they are snapshots. Only when you have the whole picture in mind can you actually derive something. Because you can present these snapshots with those particularly good values here, and if the heat pump is struggling, you simply don’t show that.

Then I can tell you that my heat pump always runs with 29/30 degrees flow from -4 degrees to +4/5 degrees. Room temperature always identical. But the power consumption is not, because there is a different compressor frequency and a different volume being pumped.
