Air-water heat pump current consumption and data

Black walls and tiles?

What is your general electricity consumption? We use 10 kWh daily. That would leave only 10 kWh for hot water and heating. That is physically impossible.

I already wrote that the heat pump reached its temperature today at 1:30 a.m. After that, hot water was still being produced. The heat pump just turned on again 15 minutes ago. Since the heat pump uses 2 kWh, it's easy to extrapolate until midnight. I suspect the heat pump will run until 12 a.m. That would be 6 hours of runtime in total over 24 hours. That means the heat pump uses 12 kWh and the household consumption is 8 kWh. But otherwise, we actually have 10-12 kWh household consumption. Definitely more tomorrow because I have to charge the car.

How can the heat pump, when it starts now, achieve the RT target with 6kW power in 4 hours at these temperatures? Especially since it still gets colder at night. Completely incomprehensible to me. You had a kfw40+ house? It is probably really that ultra well insulated.

I posted the screenshot of the data earlier. It also took exactly 5:14 hours yesterday to heat up to 28.2 degrees starting from 7:30 PM.

Yes, that is clear, but that's still not good, right? That even tops my modest consumption..

I have no idea, I can't assess that at all.

The last 24 hours produced 48.8 kWh heat, for heating and hot water. AT - 1 to - 13.2°C, average temperature - 6.4°C. Had a lot of solar heat in the house from morning until evening today.
