What do people consider a comfortable heating temperature ?

I'm not asking about the coldest you can bear, or looking for tips for dressing . I mean walking around in reasonable non summer indoor clothing and then being sedentary watching TV/reading etc. House is small, well insulated, double glazed etc, low bills to date, London.

We have just replaced our creaky old boiler with a silent new one plus (overly complicated ) multi setting thermosat/timer . We are experimenting atm with different combinations of day settings (dislike heating when sleeping). It isn't particularly easy to justad hoc bump up the heating by a bit, unlike our previous rotary dial one.

I had realised our last thermostat calibration was way off when 18C felt toasty and almost too hot. Looking at maintaining 21C/ 22 C on this new system currently. Is that a common preference ?

Heating comes on to warm the house to 20 before we get up in the morning, then off at 8am. I WFH but only heat my office during the day, I have a thermometer in the room and if it is sunny then I am happy if it stays above 19, if it is a dreary day then I need to be at 22 to not feel the cold. I wear normal clothes, including socks, slippers and a jumper. I will not dress like I am on a polar expedition to work.

The house usually drops to around 18 during the day which is fine on my non working days when I am active and I put the heating back on as it gets dark, back to 20 on the thermostat, the lounge will then get to around 21, and the rest around 20. It is off from 10pm and doesn’t drop below 16 even on the coldest nights, typically it drops to 18. But we live in the warmish SE with a well insulated house.

My parents find the house cold when they visit, but they have wood burning stoves as well as CH.

To answer your question OP I like my house 18-20 during daylight and 20-21 in the evenings to relax

If I'm moving around doing stuff then 13-16 is fine.
13-14 if I'm in bed for hours, too.
If I'm sitting still in lounge (this is with blanket) then I quite like 20+, can tolerate as low as 16-18 for a while, esp. if I have hot drinks (like now).

I'm pretty sure at work the temp is 16-18, am getting a thermometer to see.
I may need to resort to a slanket at work.

Iliketulips · 01/11/2025 09:57

Sat still in the settee, approx 18-19c. I'd be far too hot and restless anything over 20c.

We have had the exact same experience getting a new boiler last July, I feel I need to keep bumping it up every few hours. Used to sit between 16-18 in normal Autumn early winter temps, last night it was up to nearly 23 about 9. We can boost it but I often find its already past what seemed like a decent target temp already. I bought little room thermometers with humidity reading and they are reading same as thermostat so it was presumably our old system and was actually much warmer than we realised. Still struggle to get a consistent comfortable temp though.

19 21 are perfect any hotter DW is cooking along with mother nature's cruel trick on women of a certain age.

goldenautumnleaves25 · 01/11/2025 14:30

19 is fine with me, but i live a thick jumper and a blanket!

reluctantbrit · 01/11/2025 14:40

Thermostat is set at 19 at the moment, if it's a wet and damp day I may put it up at 20 if I am at home.

DH works in the insulated loft extension and still wears T-shirts as it's so warm up there and will dress normally (aka a normal jumper) around 5pm-ish when he comes downstairs.

user593 · 01/11/2025 14:45

22, but boosted to 24 before bed, then off overnight, 24 when I wake up and then back down to 22. I thought this was fairly normal, but maybe because I am from a warm country I like it a bit warmer than everyone else!

Devilsmommy · 01/11/2025 14:46

Mine is 22 because if it goes to 20 it's freezing in my flat

SlightlyBruisedApple · 01/11/2025 14:47

Everyone’s ‘comfortable’ is different, though. I once got a place in a wonderful houseshare because the previous tenant was a newly-arrived Australian who thought ‘normal’ was ‘a temperature at which I can move comfortably around the house barefoot and in shorts and tshirt in winter’. This was a 200 year old house in the west of Ireland with flagged floors, a turf stove and ancient radiators. He lasted two weeks. I moved in with my indoor Uggs and jumpers and was perfectly happy.

MrsTerryPratchett · 01/11/2025 14:56

DH turns it up to 20, I turn it down to 15. Up down up down up down.

So probably 17.5 as a compromise.

I have Scottish parents, ice on the INSIDE of the windows as children, granny’s house had no heat at all. Hard as nails (and menopausal!) here.

ForCraftyWriter · 31/10/2025 22:08

Remember it’s poss your new boiler is also wrongly calibrated.
I keep mine at 19/19.5 degrees

Indeed. It was installed in the summer, so just used for hot water until last week. The installer is coming around on Monday as the pressure reading at seems outside the parameters - am going to quiz him further about settings

shivermetimbers77 · 01/11/2025 15:20

About 20 is ideal I think

user44455557621 · 01/11/2025 19:42

About 17 for me, the rest of my family prefers 20ish, at which temp I will sneakily try to open windows.

I'm embarrassed to say I turned on the a/c last night to bring the bedroom down to 18 (London). I sleep in shorts and a camisole year round and my preferred sleeping temperature is around 15.

TheCurious0range · 02/11/2025 07:41

Ours is set to 21 from 6:30-8:30am and then on again 5pm-7:30pm when ds goes to bed, he gets too hot and sweaty if I leave it on so we just use the log burner in the evening if necessary. That's at the moment come January time when it's really cold it'll probably be on until 9/9:30. I occasionally written from home and might boost it in the day time for a couple of hours but haven't felt the bed to yet, we live in the south east and it's not that cold in the day at the moment

MissyPants · 02/11/2025 08:35

I agree on the thereabouts of 21. Mine turns off at 21.5 in a morning (it's only on for around an hour) and then again at that temp at night time (for around an hour again).

GreyCloudsLooming · 02/11/2025 13:44

It’s currently 16 degrees in my living room and I’m completely fine with no heating on. It’s not cold to us.

Rituelec · 02/11/2025 13:46

21

YouveGotNoBloodyIdea · 02/11/2025 13:54

mine is set to come on in the morning (6:30am) if it's below 18 - but the thermostat is in a hallway which is south facing with windows - so on a sunny autumn day the hallway gets warm but the rest of the house can be chilly. I'd rather give it a blast up to 20-22 when I get up than change the setting, because most of the time 18 is fine until later on in the afternoon/evening - I am often out and about in the mornings anyway.

Once I am sitting down to watch TV I usually bump it up to 20-22

I definitely need it higher now that I'm in my 70's than I did when I was in my 50's.... despite wearing jumpers.

Westfacing · 02/11/2025 13:57

Two-bed brick built flat London - I have mine set at 21 during the day, and 16 at night, using the Google Nest thermostat.

For the past three years since the new boiler and thermostat installed the heating has never come on overnight - think the lowest temperature reached is 17 degrees.

EveryDayisFriday · 02/11/2025 13:57

17 at night and 19 in the day, ours runs a low heat constantly. We were advised this was best for the boiler rather than crank on from freezing to warm in the morning and evening.

PeonyBulb · 02/11/2025 14:00

19 degrees is comfortable in my house over the winter

if the temperature drops considerably then I’ll turn it up to 20 for a while

we like to snuggle up under blankets or wear hoodies but I never go below 18 but like the perfect balance of never feeling too hot or too cold

PeonyBulb · 02/11/2025 14:00

Wear Oodies not hoodies

Westfacing · 02/11/2025 14:01

I've just checked on the Next App - over the past 10 days the boiler has kicked-in for about one and a half hours per day. It's been relatively mild in London during this time.

PeonyBulb · 02/11/2025 14:01

We have it on 6 degrees at night which is the coldest setting the thermostat goes down to
