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

We never leave it on at night

Same

18.5 minimum when temperature as now consistently dropping below 0, as husband has disabilities that mean getting up during the night.

Frost protect is for when you go on holiday in winter, not overnight. Lagging outside taps may well be necessary in some areas.

Bonden · 04/01/2026 11:59

Why didn’t you give “automatic frost protection” as an option OP?

Ours is on all day from 7am to 9pm set to 20-22 degrees. House is pretty well insulated so it still feels warm when we go to bed at 10-10:30ish, it’s back up to temp by the time we get up at 7:30.

WoahThreeAces · 04/01/2026 12:00

Heating off at night. Turns on at 6.15am.

MO0N · 04/01/2026 12:00

Never in my life have I had heating on overnight!

All you turn it off people must hate your water pipes!

Most boilers have a frost safe temp, 4-7 ish even if the heating is not on.

My thermostat doesn't seem to work so I have a choice of on or off. It's always off at night and I usually have the window open too. Have done this for years and never had an issue with frozen pipes.

Lairymary · 04/01/2026 12:01

Ours is permanently on 19 degrees.

lemondropsandchimneytops · 04/01/2026 12:01

Our old heating system doesn't have a thermostat so the heating is off at night. We often boost it for an hour or 2 just before we go to bed so toddler DD's room doesn't get too cold

ShowOfHands · 04/01/2026 12:01

We also never have the heating on at night. That's what the duvet is for. My ILs have their heating on at night and I can't stay there as I wake up with a headache and feeling awful. We don't have any of the bedroom radiators on during the day either.

Our house is insulated so without heating overnight, it rarely drops below 15 degrees, even in sub zero temperatures.

And in coherent sentences that is?

Heh I bet you say "use your WORDS" in conversation 🤣

CeffylCoch · 04/01/2026 12:02

Don’t have it on overnight however cold it gets - its warm in bed!

Lifeisforliving2025 · 04/01/2026 12:04

Never on at night and bedroom window open too. Click on in the morning if its chilly

Beekman · 04/01/2026 12:04

Ours is on 16 permanently (and overnight) and we turn it up to 19/20 when we’re going to be in. Do people really turn it off? What’s the benefit of this when it will have to work like mad to get back up to temperature when you want it warmer?

Wheech · 04/01/2026 12:05

Our is set not to drop below 14. We lost our water supply in a freeze a couple of years ago and EVERYONE from the emergency plumber on the phone to Scottish Water suggested that it was my own fault even though I told them about the lower limit but I refuse to believe it needs to be higher. When a plumber eventually attended it turned out the supply had frozen outside where the street joins my property but when someone from Scottish Water did come out (after 8 days with no running water) he suggested leaving one tap running on low overnight during cold spells, so now I do that.

I do actually..

FurForksSake · 04/01/2026 12:06

Because our house doesn’t get that cold and it doesn’t take much to heat it up. I’m sure they worked out it’s better to only have the heating on when wanted / needed rather than constantly. Particularly over night if you are heating downstairs etc for no reason at all.

FrothyCothy · 04/01/2026 12:07

Ours doesn’t have to work like mad - the heating goes off at 10pm and back on again at 7ish I think in the morning - in that time the house won’t have dropped that much, certainly not enough for pipes to be frozen or for it to take too long to feel comfortable.

We were away for a bit over Christmas and came back to the house being 9 degrees inside - it did take about 8 hours to feel warm again that day! Left it on overnight as a one off to make sure it would stay that way then went back to normal of it being off overnight.

Yes. This should have been an option as a lot of central heating systems have this.

We don't have the heating on at night as we have cosy duvets to keep us warm and automatic frost protection.

It was -5 last night here.

LadyMacbethssweetArabianhand · 04/01/2026 12:09

My heating is normally off at night. However tonight the temperature is to be -6° so I will keep it in all night.

smallglassbottle · 04/01/2026 12:10

We don't use the central heating, we have a multifuel stove which is on 24/7 in this weather. The living room is always warm (sometimes too warm) and the heat drifts upstairs. It's cold in the bedrooms, but we prefer that anyway. I couldn't sleep with the central heating on overnight, as it would get too stuffy, not to mention the expense.

mindutopia · 04/01/2026 12:11

We don’t leave the heating on at all at night. It’s too bloody clanky and I don’t like sleeping in a hot house. It hovers between 13-16c (cooler obviously in the morning). I turn it on when I get up. We’re never cold.

ProfessorRedshoeblueshoe · 04/01/2026 12:12

Never have heating on at night.
