My sister is telling me I’m a freak - but any hotter is awful, surely?

Could never sleep with heating on! Would get dreadful headache - ours is set to 18 and I find it too warm! I like the cold!

Stirabout · 19/02/2025 22:04

Personally 18 is too hot for us but we are used to old drafts houses so into our thermals.
Ours is set at 15 max but rarely reaches that unless it’s the same outside 🤣. We don’t have it set to come on at night at all as we’re all under duvets and we’d never get the benefit from heating the garden

My SIL used to have hers set at 21 and I just couldn’t stand it.

Everyone’s different and perhaps people just get used to a certain temp.

Bellie710 · 19/02/2025 22:04

Mine are set at 21, wood burner usually takes it to about 24 downstairs and 21 upstairs, minimum 18 at night, costs around £10 a day.

Pleasegodgotosleep · 19/02/2025 22:03

I suffer extreme pain when I'm too cold. I couldn't live with that at all.

GrouchyKiwi · 19/02/2025 22:01

Ours is mostly set to 18 during the day (we're home), then 18.5 for kids' showers etc at night, and then off after 8:30pm (but set to come on if it gets below 13 overnight, which thankfully it hasn't even in our draughty house in Scotland).

Most people who come to visit are warm enough, but not Swedish BIL, who always brings extra clothing. Grin I do sometimes turn it up on a very driech day as that makes the house feel colder.

WhatterySquash · 19/02/2025 22:00

Ideally I'd have it on 20, but turn it down to 18 if I can to save money. Then put it up to 19 or 20 if we're really cold. We have duvets on the sofa and lots of cosy bedclothes, pjs and hot water bottles for nighttime.

In summer I'm too hot if it gets above 25 or so - luckily live in scotland!

Whippetlovely · 19/02/2025 21:59

I put mine on at 21 but my house is old. At night I don't have the heating on as I get hot at night. My son never feels the cold and wears pants and still has the fan on at night. I don't like waking up to a cold house so it's set to 21 in the morning and after school. My dining room is bloody freezing as it has an old fashioned single payne sash window. We are going to change it at some point

18 degrees C is absolutely fine. Any warmer than that is too high IMO, and will make the house too hot. No wonder some people have such high energy bills if they're cranking the thermostat up to 21-23 degrees C! And 26 C is absolutely ludicrous!

I think people need to sort out the insulation in their house if they are having to put the heating up to anything over 21 C to heat up the house... Our house is around 90 years old, but we have excellent insulation throughout, and once we put the thermostat up to 17 degrees C, the gas boiler comes on and stays on for about 20 minutes, and the house gets lovely and toasty, and stays so for 6-7 hours... And then the heating comes on for 20 minutes again, and warms it up again for another 6-7 hours.

We have it at 12-13 C overnight. (And it rarely comes on at that temperature for the vast majority of the year...Only when it's very cold.) We hate it coming on when we're in bed! And the pipes aren't going to freeze over at 12-13 C! And no, it's not competitive stinginess, or a race to the bottom. This is what works for us. (DH and I.) Result: average gas bill for the year (including the gas cooker and hob) around £425. (3 bedroom, 90 year old cottage.)

Negroany · 19/02/2025 21:58

Mine is 16.5 in the evening , or 15 in the day time, off entirely overnight. Often 10-13 in the living room in the morning but I put it on manually so I wake up to a cold house. If I'm going out to work I don't bother putting it on, just shower, get dressed and go.

Alexahelp · 19/02/2025 21:56

Ours is 18, but it’s in the hall which is chilly. It only comes on for an hour in the morning and 3 hrs in the eve at the moment, during the day it reads 15 or so. But our lounge and bedrooms are always toasty once it’s on.

ETA - I do boost it if we’re freezing during the day! I’m not particularly hardy 😂

Sahara123 · 19/02/2025 21:55

SmileEachDay · 19/02/2025 19:38

Ohhh…
I have no heating at all on at night 😂😂

I’m with you ! 18 degrees , nothing on at night. In fact nothing on ever in our bedroom, and we sleep with a window open 🤣.

MotionofTime · 19/02/2025 20:52

God, I live in a freezer compared to most - house is usually 12 degrees.

Do you have a log burner or open fire? That's very cold.

We have ours between 18-21 depending on the day from 4pm-9.30pm and during the day if we're around. Never on over night.

Pinkypup · 19/02/2025 21:53

Mine’s at 16 during the day downstairs and 14 upstairs.
16 upstairs for a couple hours around bedtime and 14 the rest of the time.
can’t afford more

AngelsWithSilverWings · 19/02/2025 21:51

Default is 18 in our house. We turn it up to 19 if we feel chilly during the afternoon. If it's really cold of an evening we light the wood burner. We make sure the heating is back down to 18 before bedtime as we find it too hot to sleep above that.

TubeScreamer · 19/02/2025 21:51

18 here.

26!! Do you grow watermelon and lemons in your lounge! I’d be wafting around in a serong!

Or cannabis Grin

IfYouLook · 19/02/2025 21:46

Jeez I’m team 21-23 just now I am.

Haha I wish maybe I'm just compensating for my lack of exotic holidays but in all honestly it feels normal to me anything less and I have really cold hands and feet. I should change my username to tomato really 🤔

SP2024 · 19/02/2025 21:44

Ours is set at 18 or 18.5. And we have to keep it at 17.5 overnight otherwise the baby’s room goes to under 15 and he wakes up cold (two external walls and an air brick).

Strictlymad · 19/02/2025 21:42

TheJinxMinx · 19/02/2025 21:21

Too low for me id be freezing I have mine at minimum 26 in winter but im always cold i can put layers on but hate having cold air in the house. By the way I dont have it on all the time it comes on in the morning reaches the 26 then back on about 3 to again get to the 26 and at night again so its not on constant thermostat if that makes sense

26!! Do you grow watermelon and lemons in your lounge! I’d be wafting around in a serong!

TheSidewinderSleepsTonite · 19/02/2025 21:41

I find 18 a bit too cold but 19 just right

Verbena17 · 19/02/2025 21:40

Moier · 19/02/2025 19:22

Mines at 18.. it's perfect. Might turn it down tomorrow as temperature outside is set to rise.

This is what I never get…..if the outside temp goes up, shouldn’t the heating thermostat adjust itself and not come on for a bit until your home cools down to the 18 degrees - if your home is too warm?

Strictlymad · 19/02/2025 21:39

See I am a cold person, always freezing hands and feet, closing all the windows dh opens saying he wants fresh air. But…. I find central heating so suffocating and stifling. It’s not that it’s hot- it just creates the most awful stuffy atmosphere imo. So I have 18.5 ish on the day and 15 at night. Is it toasty- no, but I can’t stand it on hotter. I still have chillblains! Roll on spring

KimberleyClark · 19/02/2025 21:39

18 is fine for us.

HundredPercentUnsure · 19/02/2025 21:38

Mine is at 18dc but the house less than that generally because the thermostat is kept in baby's bedroom and the door is kept closed/pulled to to keep the heat in and regulate the temp in there. My bedroom sits comfortably at 16dc, the hall is about 14dc, kitchen about 15/16dc. Living room about 16, 17. Upstairs (loft conversion) is always warmer, more like 18-19dc.

Drafty old house!

Plus my kids and DH run warm and I run cold. If DH had his way the thermostat would be at 16.
