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

Is it an old building or why the high VLT? Everything is set wrong there.

It is a new building, we only moved in four months ago. I think they haven’t set anything at all, oh man… Wait, I’ll go back to the system and do some evaluations, if I can.

The commissioning is missing. Looks like factory settings.

Do you have a picture of the current temperatures?

Hey, take a look attached

Is this an old building or why the high VLT? Everything is set up wrong there.

Take a look at the evaluation pictures, it is a new building. What can I optimize and how? Or rather: how many kilowatt hours of electricity should the system consume per month? At least approximately. We have 170 m² of living space that is heated, except the corridors, where we have the heating turned off. Let's say 155 m² of heated area

isn't there a "not" missing?

No, the 100 kg fitter handled it quite comfortably. It also holds the window cleaner up.

The heating curve looks quite normal, very strange that it shows you some flow temperatures of 65°...

End point 40 degrees is not normal, it should be max 35. Assuming that means the flow temperature. If it were the return flow, it would be much too high, 29/30 degrees should be enough. The thing with 65/70 might only be a maximum limit in the system. It does not necessarily mean that it actually reaches that high. For that, you would need to know the control better. Also noticeable is 49 degrees for hot water, which is quite high and correspondingly energy-intensive. 45 should be enough, depending on the storage size and usage behavior even less.
