Air-water heat pump current consumption and data

Just like that? ...and before that it was 5 degrees too warm for you? I don't understand this measure as a solo measure?

Well, I don't know which air-water heat pump he has, but if he limits the maximum flow temperature, he would presumably only be able to reach the required return temperature through runtime, which would be positive. Since at the outside temperature the spread is so small, it probably won't get cold.

, no, it wasn't too warm, nor too cold. Flow was 35°C, return mostly around 31-32°C, now flow is 30 and return 28, let's test if that makes a difference

Summer/winter heating limit is at 16°C 24h average, for example, last April/May it often happened that the 24h average was above 16°C, but we still had to heat again for 2-3 days because it was super warm and then the big cold came again

Yes, so you have simply limited the max flow temperature now? Or have you shifted it in parallel or lowered the heating curve? And nothing else adjusted? Higher flow rates or similar? If the room temperature has been fine so far and you are now only limiting the flow temperature.... what do you think will happen now? :-D Edith: applied to

As far as I remember, we already turned off the heating last year in April because the entire April was sunny from the start. I remember that exactly because I was annoyed about the storage tank not yet installed, which could have made us self-sufficient overnight one month earlier.

Yes, and did you now simply limit the max flow temperature?
Or did you shift in parallel or lower the heating curve?

And otherwise, nothing adjusted? Flow rates higher or anything?

If the room temperature was fine before and you now exclusively limit the flow... what do you think will happen now? :-D

Haha, I told you...

if the ERRs are still active for you, then you won’t notice anything temperature-wise, except that the heat pump will run longer than before at the same outdoor temperature.

, no, it wasn't too warm, nor too cold. The supply temperature was 35°C, the return mostly around 31-32°C, now the supply is 30 and the return 28, let's see if that makes a difference

Which heat pump do you have? Can you manually reduce the power of the circulation pump so that your temperature difference increases?
