Air-water heat pump current consumption and data

Since your pump is probably set to automatic, it is not quite that simple. Added to this is the different length and therefore different pressures of the heating circuits.

There might still be room. Although 5 K is okay, heat pumps often run with less.

Hm in xxxx even a 6-7k spread is targeted in heating operation

Depends on the refrigerant, heat pump, minimum flow rate, and hydraulics.

Hm in xxxx even a 6-7k spread is aimed for in heating operation

I haven’t read that about the heat pump over there so far. The 6k would also be a success after yesterday and today. Then we would be at a supply temperature of 30 degrees. The heat pump probably won’t start running today as long as no hot water is being made. It’s still 2 degrees short of being crossed.

Hi, here are the csv and dta. The spread during heating operation was 5.8K. The max. flow temperature was 32.0 degrees. Heating curve is at 25/20.5/0. I increased the flow again towards the end of the heating cycle in some rooms due to the low heating curve, so that the circuits on the ground floor and upper floor are at 1440l/h. If I were to add the basement with 3x 0.5l/min, it would be 1530l/h and just below the nominal capacity of 1600l/h.

The spread in standby is now at 0.4 (well). I won't be able to adjust the heating curve for the next 2 days since we expect 2 days of sunshine. To the experts here: Can I still adjust anything on the efficiency pump and pump optimization settings or is the spread still too high? Any other ideas?

You can set the pump optimization to 5min. The heating element is enabled from -2°C, here you can safely go lower. Efficiency pump min to 5 V.
