Thermostat at 18 degrees

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

Zero degrees here outside, thermostat at 18, nice and warm!
Don’t know how I managed when it was set to 21, as per official advice (at the time)

fromthegecko · 19/02/2025 21:36

16°C. Off overnight.

Returni · 19/02/2025 21:36

Mines on 20

20-24 with slippers, tracksuit bottoms, hoodie or oodie. Blanket if I'm sitting still.

I am always cold though and I hate the feel of cold air/a cold nose.

Lately I've been going to bed in a fluffy jumper because I've been waking up cold. No heating on at night though.

I find that as long as my feet are warm, I'm fine - so fluffy bedsocks do the job for me!

We have ours 19 from 6am to 5pm then 20 from 5-11pm and off at night. It’s warm enough but not hot and stuffy. I’d find 18 cold for sitting around or getting out of the shower definitely

Catza · 19/02/2025 21:33

I try to have mine at 18 but I am wearing multiple layers as it is way too cold when I am working. If I feel rich, I'd put it up to 20 but, really, I would need it much higher than that to be comfortable. No heating after 7pm though so it drops to about 12 by the morning.

Zanatdy · 19/02/2025 21:33

20 for me, 18 pretty low

I think some houses feel hotter than others when at the same temp on the thermostat... ours feels really toasty at 18. Its often at 16 during the day and completely fine.

This.
Numerical comparison between two houses doesn't make much sense, because the thermostat measures temperature at it's small very specific spot, and while the heat is spreading in the room/house, it is heavily imperfect system, so the other end of the room has different temperature.

We have thermostatic heads in each room, and the same setting in two neighbouring rooms leads to different outcomes.

GetMyAgentOnThePhone · 19/02/2025 21:27

Goes up to 17 in the morning if I’m WFH then drops down to 16 during day / at 9am. I have a heater I use to warm my study as I refuse to heat the whole house when I’m in one room all day. Also make much use of cashmere jumpers, socks and Ugg boots.

17 in the evening and then 16 again over night.

Lassango · 19/02/2025 21:26

I prefer 17-18 maximum and wearing a light jumper in the colder months. Generally it sits between 16 an 17.

At night time it needs to drop to 15 before the heating kicks in.

Yet I was not unduly bothered when it hit 42 degrees the other summer.

User19876536484 · 19/02/2025 21:25

Ours is set at 16. It is in the hall though which is the coldest part of the house.

Patterncarmen · 19/02/2025 21:24

SmileEachDay · 19/02/2025 19:38

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

We have no heating on at night either. After 6 pm, we heat the lounge with the woodstove, but the rest of the house and the bedroom is cool. I cannot sleep in a hot bedroom.

ttcat37 · 19/02/2025 21:23

Ours is 18. Used to be lower but we have young’uns now so have to make it warmer. Anything more energetic than walking from room to room and I’m sweating, it’s too warm for me.

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

SunshineInMySprocket · 19/02/2025 21:21

18 is the max during the day and I turn it right down to 15/16 at night. I couldn’t sleep any warmer as it gets hot upstairs.

Potsofpetals · 19/02/2025 21:21

I have mine at 28 upstairs and keep the windows a jar all year. 25 downstairs in the evening as I don’t want windows open. I don’t get sick and my house is dry. I can’t imagine living in a cold house, in itchy jumpers. I’m sitting here in vest and shorts. I’m just right.

isitmeamithedrama · 19/02/2025 21:18

18 is perfect for my house well downstairs upstairs I keep it at 17
My partners house has to be 20/21 otherwise it feels chilly. His house is bigger though

WalkingWavy · 19/02/2025 21:17

We’re a 23 household! DP says we don’t work full time to be cold in our own house so he always has it on and swans around in shorts and tshirt. We’re in Scotland too so perhaps a bit colder than down south

OnlyTheBravest · 19/02/2025 21:16

It does but I have trv's on the radiators and we tend to leave the window vents open.

It may be weird but it works for my household.

MumCanIHaveASnackPlease · 19/02/2025 21:16

SmileEachDay · 19/02/2025 20:54

No no NO.

21 is stifling.

Unless you’re on a beach. Maybe you live on a beach?

Just Scotland if that makes a difference!

Downstairs (living spaces) 21c.
Upstairs (bedrooms) 18c

WFH in 18c does not work for me I feel too cold .

Does heat not rise in your house? 😀

It has always seemed strange to me that in summer, 18 out of doors is warm ... but in winter, indoors, it's cold. At least, that's my perception of temperatures!

Probably because when I am sat at my desk working I am not moving around, but when outside I am gardening or walking.

BeaAndBen · 19/02/2025 21:09

Depends how windy it is! My house gets awfully draughty.

Therefore 17 degrees on a still day is really warm while 20 on a blustery day is cold.
