Heat pump consumption 2019 on a monthly basis

that is at least not little. Hot water at 50 degrees is fine, but lower the hysteresis from 2K to at least 6K. I think the high consumption is rather due to the flow temperature and the ERR.

do you have a cellar?

Sounds at first like a very high consumption for a Kfw 40 with 150sqm. But it's also located high up and supply temperature in the forest..

After my optimizations, I have gone from 60 kWh daily to about 30 kWh. However, I still find that too much. The goal would be 20 to 25 kWh at minus 3 degrees. Then it would be acceptable compared to others. I just don't know what else I can adjust at the moment.

20-25 is okay, if one uses less with the same house, has large south-facing windows, lower temperature in the house, flow temperature a bit more insulation, ventilates less... and so on and so forth.

I don't find 30 for the building size entirely unrealistic. That also fluctuates from day to day.

What settings have you come to now?

Oh, "goal would be," sorry, misread
