Underfloor heating air-water heat pump. House too warm when the sun shines

Ok, thank you. We heat 190 sqm of living space. We have hot water at 47 degrees, circulation from 6:45 to 10 am and 5 to 7 pm and 8 to 10 pm.

We consumed 24 kWh yesterday. A hot water cycle of 42-48°. There is no circulation. The average temperature in the house is 21.5-22°. Heated area is 219m², KFW 55 with 18.9kWh/(m²*a) primary energy demand.

We also have the hot water hysteresis set to 6, so we are between 41-47 degrees.

Wow, so little kWh consumed! That is great

M4rvin, very good power consumption.
