What’s your thermostat set to?

My DP really feels the cold and has the thermostat set to 21 degrees from 6.30am til 10pm and 15 degrees at night. If I turn it down to 19 degrees he complains so I just wondered how warm you try and keep your house?

24deg centigrade 24hrs/day

Its for Elderly Mr DH, who is scheduled shortly to be admitted to Thoracic ward Harefield hospital with multiple issues including significantly impaired mobility and heart/circulation

i have to warn anyone who comes to visit to bring beachwear. My elderly mother was the same. Sigh. I keep a fan by my bed and often need to run it

18 in the day, off at night.
based in scotland, if that helps.

Bigcat25 · 29/12/2025 19:25

21

Off at night, small window open.
20-22 in the day.

cupfinalchaos · 29/12/2025 18:44

We have underfloor heating set to 22 all the time.

Simonjt · 29/12/2025 18:37

21, off overnight as it doesn’t get below 16/17 at night.

CoffeeCakeAndALattePlease · 29/12/2025 18:36

20-21 depending on how we feel.
we both wfh and have sedentary jobs so get chilly just sitting still.

lobsterkiller · 29/12/2025 18:34

17-17.5c twice a day. It's ways off on a night time.

I've got a log burner for very cold days.

WrigglyDonCat · 29/12/2025 18:32

5 at the moment as heating off as I'm still busy and always dressed for outdoors in winter. Once I stop doing stuff it will go onto to 15 until I got to bed then off and windows open upstairs. But I wear thermal base layers top and bottom, trousers, top, thick wool jumper pretty much every day in winter.

Titillateanocelot · 29/12/2025 18:32

19 is perfect.
18 is too cold and 20 is sweltering in my opinion!

vanillalattes · 29/12/2025 18:29

We just put ours on as/when we need it - never any warmer than 19 degrees though and only for a couple of hours at a time. Always off at night as well.

WinterWooliesBaa · 29/12/2025 18:28

It depends where your thermostat is as to how warm a house feels at different temperatures. Knowing what other people have theirs set to doesn't help.

mine is set at 21.5, but it's portable, so if it's in the lounge (radiators on high) the house is quite a different temperature than if it's sitting in the bedroom (one radiator on low) because if it's in the bedroom it's waiting for the single radiator on a low setting to make the bedroom 21.5° before switching off, but if it's in the lounge the radiators on high get it to 21.5° quickly & turn off. The hallway is somewhere in the middle.

mine is currently in the lounge set at 21.5° but it still feels cold in here because I have been away for a few days ' it was in a low setting, so no residual heat in the furniture.walls etc.

it's a new thermostat & I need to sort out the programming.

so if your thermostat us portable. Put it somewhere colder & your living area will get warmer. But he won't whinge because it'll still say 18°

We have ours on at 24 downstairs and 20 upstairs.

BUT our door and window seals are fucked. So we lose a lot of heat out them and need to have the heating on higher to compensate. And we live right by the North Sea. Windows and doors Being replaced in February thank god.

HollyhockDays · 29/12/2025 18:16

It’s not on overnight. We don’t use the timers just put it on manually - downstairs is about 22 upstairs is 24!!

GlitteryUnicornSparkles · 29/12/2025 18:08

When it’s on (generally early morning for an hour or two and then 3pm-8.30pm if we’re out of the house at work / college, otherwise its on most of the day) usually 18 or 19 degrees, occasionally my son will turn it up to 20 if it’s really cold.

I don’t understand people having heating on overnight whilst they’re asleep, seems like an unnecessary expense, isn’t that what thick duvets and hot water bottles were invented for!

SilverTonsel · 29/12/2025 17:54

18 degrees when it is on, which is usually a few hours per day. We wear thick hoodies/jumpers.

9 degrees. Genuinely 🤣. Have the heating on a couple of times a day. Let it get up to 20, then switch it off. We have log burner in the lounge most evenings though.

embarrassedparent2025 · 29/12/2025 00:23

20c from 5:30am - 22:00. 17.5 overnight

Also if 1yo DD bedroom drops below 17.8c overnight the heating kicks in for 30 minutes. She wakes up if its cold overnight

isitmytime · 29/12/2025 00:21

14 if I’m out the house, working staying with DP or sleeping etc
17.5 upstairs
18.5/19 downstairs.

I hate being too warm and if it’s really cold I just chuck on an extra layer or grab the sofa throw while I watch tv

LBOCS2 · 29/12/2025 00:21

16.5/17 when the heating is on - but it’s not on all day, a couple of hours in the morning and then early afternoon and in the evening it’s on for 4hrs. Completely off overnight.

Eggseleventwelve · 29/12/2025 00:18

21c . Can’t bare getting up to a cold house. Just back from Oz !

HeddaGarbled · 29/12/2025 00:17

Pick a number, any number.

Cursula · 29/12/2025 00:17

16 and we wear clothes ! Weird going into other peoples houses and seeing T-shirts but that’s because they have thermostat at 22. Each to their own.

converseandjeans · 29/12/2025 00:16

6-8am 21
8-3pm 14
3-10pm 21
overnight 14

18 seems very low but it might depend on layout & how well insulated the house is.
