Air-to-water heat pump consumption at 30 kWh per day

We have now lowered the heating curve by 1 and the consumption has dropped from 30kWh per day to 20kWh per day.

That does not sound plausible. Has it also become warmer outside? Was the waiting time long enough? About 48 hours?

Typical beginner's mistake. The house is 1 degree warm and you initially save this energy for free. Your note about the 48 hours is therefore correct. After that, consumption increases.

so I firmly believe in a mistake. 24°C room temperature with 30°C flow temperature, 10cm VA and outside temperatures below zero?

We have 23 degrees room temperature in the living room, 20/21 in the bathrooms and other rooms, and about 18 degrees in the bedroom. At 22/23 degrees calculated flow temperature and 27/28 degrees flow cut-off temperature and temperatures below zero. I have not yet reached the point where the flow temperature needs to be increased, at the moment the heating still regulates this via the running time which is between 14 - 20 hours. 150m2 Energy Saving Ordinance with slightly improved wall insulation.

You definitely don’t have a parallel shift of the heating curve in there, do you?

I have to run about 5°C higher in the flow to reach these temperatures. :eek: So the heating curve you use in the flow, I use as RL_soll
