What temperature do you leave your heating on at night? When it's below zero celcius outside?

Just wondered, after a little debate beween me and a few other people yesterday.

Would you be so kind as to pick an option? (I will put what I leave it at a bit later.) Thank you. Smile

Never have heating on at night

wonderstuff · 05/01/2026 23:03

I have the radiator in the bedroom off and I had window open last night. I love a cool room at night. I think the rest of the house is programmed to keep it slightly above freezing over night, I don’t really understand my thermostat control. It’s a modern well insulated house so probably doesn’t drop below 16. During the day if we’re in I like it at 21.

Timed to be on 530-630 and 430-9 only.

Hearings never on at night.

I don't have the heating on overnight.

Excitingnewusername · 06/01/2026 17:04

Voted 10 and under as there's no its not on overnight option. (We don't have a thermostat either, though currently very tempted to get one installed!)

Poppy61 · 06/01/2026 17:49

Turned off at night; back on in the morning when I get up.

Do it! I would have thought it would pay back very quickly. Consider thermostatic radiator valves while you're at it, if they are suitable for your system.

lljkk · 06/01/2026 18:55

cost to drain my system and put thermostatic valves on 4 of the 7 rads in my house = £380 with VAT. I would lose money if i had them fitted. I can / did manually shut off 3 of them, instead.

The thermostat has "frost protect" which is 9°C that is all that is on overnight but when I look on the app it is about 14 at the lowest.

People that don't have heating on, or have it very low at night, do you do that when you have babies that wake up in the night? I can't bear the thought of having to get out of warm bed into a cold room and feed a baby multiple times a night. Actually I did do that for the one winter I lived in a cottage that my ex insisted we only heat with wood fires so at night the temperatures would drop below 12 degrees and it was hellish waking up with my baby and in the mornings we would be freezing until the kitchen stove fire heated up enough to warm the kitchen for us. So can't imagine willingly choosing to do that, so I guess people keep the heating a bit warmer at night with small babies?

And I developed asthma after that winter in that house. Not heating a house properly can lead to mould in the walls which can cause all kinds of health issues. The house ended up being ruined thanks to my ex not heating it properly (I left him after that winter and moved to my own place which was warm all the time) so the landlord was really pissed off too.

StarlightLady · 07/01/2026 05:59

I have a very warm duvet as l can’t sleep comfortably if l wear anything in bed. Boiler is set at 9c overnight to prevent bursts and frozen pipes.

My house is 3 storeys and very well insulated; the thermostat is on the ground floor in the coldest area of the house. So when it drops to 14 down there in the night (pretty rare, only when sub-zero outside) the bedrooms are still pretty comfortable. My kids are older now but while they woke up plenty in the nights, I never remember the worst bit being feeling cold!

That doesn't sound so bad then, certainly not as bad as it was for me

Sunshineandgrapefruit · 07/01/2026 19:05

Ours is off overnight. Always. We just blanket up.

Sunshineandgrapefruit · 07/01/2026 19:06

When the kids were tiny we would have an oil heater in their room overnight if it was too cold

WinterWooliesBaa · 07/01/2026 19:11

Just on frost setting (7° I think) but is usually stays 17-19° overnight. But has dropped to 14 this week! Taking quite a while to get back up ti 21.5°, but I can't have it on in the early hours as it wakes me up & id have only just gone to sleep.

AffIt · 07/01/2026 19:16

Heating never on overnight. We're in the rural west of Scotland.

It currently comes on twice a day (6.30-9.30am then 5.30-9.30pm), set at around 20 degrees.

Frost setting is 5 degrees, but it's a big, old, traditionally-built stone house and well-insulated - as long as it's heated a couple of times a day, the ambient temperature is always fairly pleasant (we also have open fires downstairs).

The frost setting has never had to kick in as long as we've lived here.

mellongoose · 07/01/2026 19:29

Ours is off but will kick in if the kitchen drops below 8 to stop the pipes from freezing. We are in Cornwall so this never happens!!

Youspurnme · 07/01/2026 20:18

Thermostat is set at 16 but I don’t have the radiator on in my room anyway. Im menopausal so my body temperature has a mind of its own, generally tending towards heat 🥵
