What do you set your heating at?

Please settle an argument with me and my mother.

What do you set your heating at? Is it different in the day and the night?

Just trying to gauge what the 'norm' is here. We are South East (not that that makes any difference - temp is temp).

For me - 20 in the day, 17 at night. My boyfriend (who lives with me) is 22 day, 19 night so its gone up - I wouldn't want him feeling the cold.

My mother thinks a house that is 14 is perfectly reasonable, and not on at all at night. She rarely puts in on. This worries me desperately as father has had pneumonia and they are in their mid 70s. She is convinced I, and 'my generation' are wussies, and heating is bad for you, and they are normal and I 'feel the cold more than most'.

I guess I want to prove to her that that last line is inaccurate, and she puts her bloody heating on this winter, as I am super anxious about their health (particularly my dad). On a selfish note, I loathe going round there as I sit shivering, whilst being given a blanket and told 'oh dear, you do feel the cold don't you'. Like Im some sort of alien. The offer of heating is never there, and when it is put on, it is with much complaint, and mum performance huffing and fanning of brow. Ugh. Drives me nuts.

I’m in Scotland. Its set to come on at 18C about 4pm and go off at 10pm when it’s set about 8C, and only just been switched back on after a long summer break.
Radiators in bedroom are NEVER switched on and windows open in bedroom all year round.
im just back from staying in a hotel for weekend and feeling quite ill because it was so fecking hot everywhere, I’m sure I picked up the lurgy because of it.
why can’t you be in control of your own room temperature - such a waste of energy and dosh.
I know everyone is different but I feel like I can’t breathe in a warm, stuffy room.

YourDandyPlumBeaker · 14/10/2025 18:01

Ours is set to 20°, but only when we're at home (16° if we're out all day or at work etc). Goes off every night at 9 or 10, depending on bedtime, even in middle of winter as house stays warm, and comes on early morning before we get up.

RunningJo · 14/10/2025 18:04

never have the heating on when we are asleep, we have it at 20 degrees on a timer during the day, in winter that’s around 1.5 hrs in a morning, then around 4.5 hours at night.
If it’s really cold, we’ll override the timer and put it on (after I’ve told everyone to put a jumper on first)

FlubandSlub · 15/10/2025 00:20

I live in a modern well insulated flat. The temperature is currently 22°. It's 15 mins past midnight and 7° outside. My heating hasn't been on since March!

Nannyfannybanny · 15/10/2025 12:56

Everyone is obsessed with damp, cold air,very dry. air is equally bad for you. Central heating dries your skin, sinuses,in hospital, you're given humidified 02, for bronchial conditions, Croup, humidifiers,steam inhalation.

Allmarbleslost · 15/10/2025 16:54

18 in the day and off at night.

HorrorAndHaagenDazs · 15/10/2025 16:59

18-19 during the day and off at night.
I hate a cold house.

Hollietree · 15/10/2025 17:03

Your house seems very warm to me, but you are paying the bills so up to you if you want high gas/electric bills 🤷🏼‍♀️

Your parents sounds a little in the cold side to me, but are they struggling to pay the bills? Is it a necessity?

Jayne35 · 15/10/2025 17:55

20 between 6-9am, then 15 until 4pm when it’s 20 again until 10pm. If up late I will put it back on but generally set to 7 overnight, and it never comes on. Hate heating on at night. Though this wasn’t the case when I had babies/toddlers due to getting up in the night I left it on about 18.

XenoBitch · 15/10/2025 17:59

I have not got it set to anything right now. It is 16 in my house and I have the back door open for my dog.
I feel fine, but obviously acknowledge other people would be very cold at that temp so have the heating on.
I just don't need it right now.

amibeingaknob · 16/10/2025 11:01

i guess the issue is two-fold isnt it.

  1. that i think they are putting their health at risk due to age, and dads health issues.
  2. that i think its bloody rude to not heat a guest.

The former I don't think i can do anything about. I tried, and failed.
The latter I can. I can simply refuse to go there and tell them why, or insist that the heating goes on before I come.

When i think back to the other day (and its like this every year), i stayed in my coat, i was shivering - and mum made lots of performative 'oh you do feel the cold don't you dear- heres a blanket' and lots of laughing and mocking me for being so fussy. I find that incredibly rude and disrespectful. I couldnt even imagine not putting heating on for someone else if they are sat there still in their coat!! Let alone shivering.

I think its rude for me to insist on heating and Id never do it normally, BUT, i think its far ruder what they are doing. And when I get pushed I will tell them so.

Never ever had the heating on over night! In fact, we don’t ’set’ our heating at all! We put it on for an hour if it gets a bit nippy and then turn it off. It’s nothing to do with cost but the fact that we’re all run hot!

Rexthesnail · 16/10/2025 12:53

23 all the time

My dream house (maybe not so much at night).

mummymissessunshine · 16/10/2025 12:58

i set it to 22 6am-9am and again 5-10pm.

overnight and during the day I set the base to 12 but I expect I will pop it on over the winter for a few hours at 22 during the middle of the day. As I hate to be cold!!!

14 is too low for elderly people for all of the time. There is some guidance on central heating via one of the elderly charities. Will see if I can find it.

Didntask · 16/10/2025 13:00

16 minimum. Heating is on all day (we're home most days), but i often crank it up manually to 22/24 in the evenings. I like being cosy.

mummymissessunshine · 16/10/2025 13:01

From the internet….
How warm should a home be? Health experts recommend that during cold weather spells, and for people aged 65 years or more, a healthy home – day and night – should be at least 18 degrees centigradealthough, in living areas, a higher temperature of 21 degrees centigrade might be more comfortable.

Allseeingallknowing · 13/10/2025 15:20

Below 16 centigrade you’re at risk of respiratory disease, according to official figures. Our is set at 18 downstairs, 16 upstairs.

There was research last year that sleeping at around 14 helps prevent certain forms of dementia.

Agrumpyknitter · 16/10/2025 13:06

We’re down south so we have it on for 45 mins in the morning and then for an hour to an hour and a half in the evening. I turn it off after 8pm as it’s too hot to sleep. When it gets much colder I will
have it on for longer but not too much at night. We fall and stay asleep better when the bedroom is cooler.

millymollymoomoo · 16/10/2025 13:06

19-21 day, 15 at night

TotallyAddictedToCoffee · 16/10/2025 13:16

Off

😂

Glittertwins · 16/10/2025 14:18

Each room has its own setting during the day, depending on who is in the house. We tend to have it around 18c when everyone is around, usually only at the weekend.
The bedrooms are set to 16.5 at night. One bedroom gets quite bad condensation so having it a bit warmer helps. Downstairs and unoccupied bedrooms are cooler.

coxesorangepippin · 16/10/2025 18:44

Ours is at 21

MidnightMeltdown · 16/10/2025 19:07

19 or 20 during the day, depending on how much I’m moving. Off at night. I can’t stand sleeping in a heated house. I like the room to be cool at night.

notthatoldchestnut · 16/10/2025 20:14

Around 17-19 during the day here. Always off at night. It never gets below 14 even when it’s at its coldest in our house but we are well insulated. I think 14 is far too low for daytime.
your mum is right that too much central heating isn’t good for you. It dries the air and makes me feel unwell
