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.

So always keep an eye on the weather forecast. If the following day is going to be warm (or sunny), then heat less at night, otherwise keep it constant. This could actually be a practical case for smart heating control. Although it is often said that a well-planned and properly adjusted heating system doesn’t need any additional regulation.

Oh, does the original poster have drafty windows? I must have missed that.In #10, he mentions there is a draft. I interpreted that as coming from the windows, not as "a draft from the living room to the hallway." In that case, lowering the temperature at night would make even less difference anyway.
I also believe that this varies from house to house. The general statement made by our politicians, in my opinion, is completely off. For example, lowering the temperature at night with underfloor heating is absolute nonsense.
Even in older houses, I’m not sure if it really makes sense.
Previously, we lived in a house with natural stone walls that were 50-80cm (20-31 inches) thick. The oil heating system also had a night setback programmed. However, at night the rooms cooled down so much that it took a long time in the morning for them to warm up again. This was not comfortable.
From my perspective, it would have made more sense to keep the heating running at a lower supply temperature instead.
