Hello everyone,
so far, I haven’t found a satisfactory answer.
The topic is energy saving in today’s context.
Does lowering the room temperature at night really make sense? There are impressive claims from smart thermostat manufacturers about how much energy can be saved, including with geofencing features.
But is that really the case? Don’t I end up using the energy saved at night to heat up cooled-down furniture and walls again? Is there any real-world potential for savings?
Thanks for your input.

That would only make sense from the perspective that you could, for example, heat during the day using a heat pump powered by cheaper photovoltaic electricity from the roof, or that the significantly warmer outdoor air during the day makes the air-source heat pump more efficient accordingly. I have been thinking about this over the past few days and would like to start working on it soon.
Specifically, to achieve the most efficient or economical operation possible with the combination of an air-to-water heat pump and photovoltaics, or to greatly compromise on comfort. So that it doesn’t get "too warm" during the day and "too cold" at night.
Is there a general recommendation on the temperature difference between day and night that should ideally not be exceeded or fallen below?

Oh, does the original poster have leaky windows? I must have missed that.He doesn’t have leaky windows either. I actually suspect the leaks are coming from somewhere else, for example the chimney. When it’s windy outside, the flue can draw warm air out.G

No one knows how your house behaves thermally. I set 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 guess I need to adjust it again.
