Is night setback sensible? - Experiences?

That would only make sense from the perspective that, for example, you can heat during the day with a heat pump using cheap photovoltaic electricity from the roof or that the significantly warmer outside air during the day makes the air source heat pump correspondingly more efficient again.

I have been thinking about exactly that in the past few days and would like to tackle it soon.
In other words, to set up a combination of air-to-water heat pump + photovoltaics for the most efficient/thrifty operation possible or to significantly forego comfort. So that it doesn’t get "too warm" during the day and "too cold" at night.
Is there a "general" recommendation on what temperature difference between day and night should ideally not be exceeded/undercut?

Oh, does the OP have drafty windows? I must have missed that.

He doesn't have that either. I suspect the leaks are rather elsewhere. For example, the chimney. When the wind blows outside, the flue pulls the warm air out.

The only way is to experiment. No one knows how your house behaves thermally. I switch the heating to "Eco Mode" from 7 pm to 5 am with a significantly reduced target temperature. If my wife then complains about cold feet in the bathroom, I probably have to adjust it again.
