Curious what temperature everyone has their thermostat set to… and do you keep it on at night too?
Also:
Got mine set between 5 & 6 no idea what that means but it seems to be warm enough. I turn mine off at night & put it on when I get up,
C/H is gas warm air.
Easily answered - no central heating. And the wall mounted electric heaters in the upstairs rooms are too expensive. So I fire up the large wood burner in the morning; by lunch time it is warm enough in the main room to open some doors and let the heat through the house. This means the bedrooms are pretty chilly all the time - perhaps 10-12 deg C. I sleep better with cool air and a very warm bed. But it does become a bit testing with nights like this coming week - mostly negative 3 or 4 deg.
Since utility bills are insane here in CA, I don’t set my thermostat at a certain temperature unless I have company. I turn the heat on when I’m going to do anything in the kitchen & when I’m in the shower (along with a space heater), then I turn it off when I’m done. I dress warmly in heated vests. I’d rather spend the money on clothes that I’ll have for years than paying crazy utility bills each month. For sleep, I dress in thick polyester & use two blankets.
When I have company a few times/year, I set the thermostat on both air conditioners at 73.
A lot depends on type of boiler and hot water pipes behing the walls. We have what is called microbore piping so a combie boiler is not the ideal. It could pump too much pressure on the pipework and blow apart a joint. Also a good idea to have a filter to catch any sluding in the heating system. We have just had one fitted to comply with regs. This after having the whole system pressure cleaned out done professionally. I was surprised how much acculimated sludge was within the pipes.
As for how hot to keep a house and for how long? This is a highly variable question. First what your heating up, just radiatiors or/and towel rails. If you going skinny dipping in an ice cold bath or trying to go for a sauna. 
the area your trying to keep warm is a viable consideration let alone how many rads to heat up and their position
One tip we are using is heat shields between rads and wall to reflect heat outwards and not into an outside wall.
Bleeding rads helps by releasing air pressure via loosining up a plug at the side/top an hear the air hiss out
as for actual temperature the answer is what you happy at and cost of heating,there is no def this or that to the question but using a timer cuts down heating bills
We keep it 20C. If it gets warmer than that (in the summer for example) the thermostat automatically shuts down. No action required.
Central heating?? I haven’t even got air con!
I have several pedestal fans and two fan heaters - everything you ever need.
That nice Mr Rudd’s roof insulation made a big difference to my house.
22C, toasties good.
We have CH coming on at 05:30 every morning for 30 mins. We switch it on/off throughout the day as we need. We used to have a thermostat on the wall near the front door but I disconnected it. I’d rather control it myself as we are in & out at different times throughout the day.
I adjust it as and when. It hasn’t been too cold (yet) down here in the south east.
I’m not convinced those make any difference.
I’m intrigued about the microbore pipes. Is that common in mid 20th C build?
Central underfloor heating probably set to 24° in the living room and study, a bit lower elsewhere. It’s set to feel comfy not to an exact value. It gets lowered during the night but not much.
At the moment I have the thermostat set a 21c and the flow temperature at 70c. When it is not so cold I reduce the flow temperature to 68c. The hot water temperature is set at 57c.
A bit chilly here this morning. We have a couple of these for extra heat, and they chuck it out.
About 18 inches high.

Luckily I bought 12 cubic metres of fire wood over the summer as this is going to be a cold week. I got the living room up to 28 deg yesterday evening (and there is an open space through to the dining room)! Chucked a big log on (10 kg maybe) last thing before bed and it was still burning at 8am this morning. It is kind of like a thermostat…
Reminds me of my childhood: old farmhouse, big central fireplace, big heavy logs that would smoulder all night.
Temps here in London
I leave my boiler on all the time, 24/7, unless I go away in the summer months.
At the moment the main thermostat is set to 10°C because I’m away from home.
I can control the thermostat from my iPhone and I can see that the boiler has only fired up a few times over the last couple of weeks and run for a total of just over 2 hours.
I will be turning the thermostat temperature up to 18°C before I set off to drive home this afternoon. Hopefully, it will be warm and cosy by the time I get home.
When I return home, I will switch the thermostat schedule back on. It is set to 18°C from 7 am and is set to reduce to 16°C at bedtime. If I am going out during the day or for the whole evening, I turn it down to 16°C.
I have found that I use less gas overall, if I don’t let the temp drop below 16°C at night.
I used to have my thermostat at 20°C when I was at home during the day and evening in Winter but started reducing the temp down to 18°C when energy prices started sky-rocketing a few years ago.
I used to find 18°C quite chilly if I was just sitting relaxing in the evenings, so I treated myself to a furry sofa throw which is like an electric overblanket - it keeps me cosy and warm when I’m not moving about.
I’ve got used to living in 18°C now. I usually turn the thermostat up to 20°C if I have visitors - but I find it’s too warm for comfort for me now, so I have to strip down to a short sleeved t-shirt!

Microbore pipes for central heating . The idea was/is a cost cutting exercise across the UK . Problems such as using combi boilers which used too much pressure causing the thinner pipes to split ot connection joint to come aparts. so if changing boilers get a plumber in who can tell you which boiler to use beforehand
Effective When ambient below 15oC.
Gas C/H. 2 of 7 Rads permanently turned on. Both downstairs. Convection to the rest of the house.
Set for 16oC Daytime. Thermostat Manually bumped up to 21oC. @ Sunset.
All could be set to Auto. But conversely find this bumps up the usage Meter. !!
Not exactly balmy either…
