I've recently become interested in "house temperature" from a conversation at work, plus I have smart heating conrols (all but one radiator also use a Smart TRV) which consistently tells me my house is cold and humid.
Doing some research, most articles agree on 18-21/22degrees (especially overnight during sleep). This is simply far too warm for us. I woke up this morning at 13.4degrees and was slightly uncomfortable on the warm side, always sleep in just boxers 365 days (so I have the window quarter open which dropped the room temperature to 12.5degrees as of right now). If I had my heating set to come on below 18degrees it would be on all night for one thing, and be even more uncomfortable. It'd also continually be battling with smart heating "open window feature"
As far as schedule goes, this is what I have mine set to;
00:00-08:00 = 10.0
08:00-22:00 = 14.0
22:00-00:00 = 10.0
One exception is bathroom, which has 2 extra blocks, and only really to warm up towels;
07:30-08:30 = 22.0
16:30-17:30 = 22.0
And we just boost it when we do feel a chill.
So interested to see what others are doing.
