Disagreements over what temperature to have heating set to.

Partner and I rarely disagree on much, but he’s getting strangely wound up over the temperature of the house.

For context, I rarely have heating on until the winter months, but I do like it on when people are bathing/showering so you come out to a nice warm towel and aren’t freezing in the bathroom.

I only have the thermostat set to 18 degrees so I don’t feel it’s overly warm, but he’s walking round trying to throw the windows open whereas DD and I are shivering and chucking on layers. He’s the type of person who would permanently sleep with a fan, and we do have a summer duvet on all year round to help with him over heating in the night and I just whack extra blankets on me. Every window in the house is also always slightly cracked open because we like the fresh air.

How do I resolve this? What’s the happy medium? And for interest - do you think 18 degrees is too warm inside?

At least 18 for me.

dementedpixie · 18/10/2025 16:53

Ours is set at 18/19⁰C but only for a few hours am and pm just now. Ive only just turned it up to that as its started to get colder where I am; previously it was at 16/17⁰C. If we get cold in the daytime we can put a cardigan/jumper on

DierdreDaphne · 18/10/2025 16:53

I agree that 18 is not very warm - we set ours just below 20 (both in our 60s mind) how does your dp cope in summer when it's above 20 outside all day???

If i was living at 18 deg I would layer - so leggings (and knee socks) under joggers; vest/singlet then a long-sleeve tee under oodie or jumper. Just a t-shirt then an oodie sounds drafty!

21 is far too hot for a long coated dog like that.

How do longhaired dogs cope in summer?? I don't think ive ever seen a retriever with a haircut 🤔

PearlClutzsche · 18/10/2025 16:57

I have to fight with DH to get it lower than 22... he routinely sets it to 24!
I spend the whole winter sweltering, and can't wear the lovely jumpers I've knitted. I hate it.

I think DH would literally die if the thermostat was at 15!

pizzaHeart · 18/10/2025 16:57

18 is absolutely normal and different people feel temperature differently, it’s genetics so he should be more understanding.
Could you put thermostats on radiators on different settings? E.g we have it on 2 in DD’s bedroom but on 3 in ours and 4 in the living room.
I think layers wise if you have fleece, joggers and socks on you’ve done enough and the next step is to up the temperature if you can afford it, if not it’s a different situation.

EuroTour · 18/10/2025 16:59

In laws have it set to 26° I refuse to visit. 17/18 is fine. Haven't had any heating on yet...

Mumofteenandtween · 18/10/2025 17:00

We have ours at 20 and I am currently wearing a thermal t shirt, a long sleeve t shirt and a jumper. When sitting still I add a blanket.

Dh wears a t shirt and shorts.

Purplecatshopaholic · 18/10/2025 17:02

I’d be freezing at 18! Never less than 21 here if I can help it, and preferably nearer 24, can’t stand being cold.

angustifolia · 18/10/2025 17:09

Windows cracked with the heating on would drive me insane.

If he's already wearing a t-shirt and shorts, I think he's doing his part to adapt. Unless someone's ill, I'd suggest extra layers, heated throws, or a small portable heater in a room that can be shut off from the rest of the house.

(I've had double-coated dogs in climates where even with AC the lowest it gets in summer is the mid-70s. They're fine, though they do love to spend time outdoors when the temperature drops.)

canklesmctacotits · 18/10/2025 17:12

It’s always possible to put more clothes on, there are only so many clothes a person can take off. I say this mid-hot flash.

Winteriscoming80 · 18/10/2025 16:35

18 in my house would be freezing in winter as it’s a very old house,in a new build that would be toasty.

Surely 18 is 18?? Or do you mean your house is damp so feel colder at a given temp? If so would a dehumidifier help you at all?

KvotheTheBloodless · 18/10/2025 17:17

I've always read that the best temperature for good physical health is 18°C, and that's what we set our thermostat to.

Any colder is associated with worse health outcomes, so despite my personal preference for colder rooms I follow the guidance and stick with 18°C for DH and DS's sake.

Teathecolourofcreosote · 18/10/2025 17:18

On these threads I always wonder where the thermostat is.

If it's in the hall or an outer wall your 15 is likely higher elsewhere in the house.

BreakingBroken · 18/10/2025 17:20

18.5 at night
20 by day

2025VibeandThrive · 18/10/2025 16:18

I think 18 is too high. 15 feels more reasonable to me.

Ours is at 15.

FleurDeFleur · 18/10/2025 17:29

youalright · 18/10/2025 16:37

We have it at 20. I cant believe how cold some of your houses must be

Edited

Oh, I'm the same. It's never lower than 20°c in my house. I like to relax in comfort. However beware of all the competitive under heaters on here.
Ignoring NHS and govt guidelines, usually!

We have a giant breed with a double coat and they've all struggled in summer. They have to be walked very early in warm weather then they'll spend the whole day indoors on cool tiles with the blinds closed and a couple of big fans blowing. They're natural moulters so the coat thins out in summer (the same is true of Goldies I believe...?) Our current girl is back to being like a big woolly bear right now, hence us not having any heating on at all yet. It's currently 15 in the house, which she doesn't mind, but she loves to lie outside as much as she can, even when it's frosty. They just aren't suited to heat at all.

CrushingOnRubies · 18/10/2025 17:31

21 degrees here. Wearing double socks, and three layers and wrapped in a blanket with heating on and I’m perfect temperature. Do find that it depends if it’s sunny outside or not because the sun streaming in warms the room up. But it’s been so cloudy this week the room has felt colder

Silverpaws · 18/10/2025 17:31

Our heating comes on if it dips below 9 degrees. I am permanently cold, he's in a tshirt.

Ours is upstairs in the back bedroom, which is the warmest part of the house.

ishimbob · 18/10/2025 17:33

Our office temperature was 18 last week when there were some issues with the heating and almost everyone was very cold at that temperature.

At home, we keep it at 19/20 which is ok with layers but isn't exactly toasty.

Yes, that makes a huge difference with our windows.

Changename12 · 18/10/2025 17:34

I would freeze at 18. 21upwards for me. All the people who say they keep their temperatures low for the dog, don’t you walk the dog in the summer? I had a couple of long walks with a friend and her golden retriever this summer. The dog was fine and enjoyed the walks.

665theneighborofthebeast · 18/10/2025 17:34

We have a movable thermostat, a draughty if well insulated house, dogs cats kids and menopause.
There is no correct temperature.
Sometimes the dogs get cold and you unsuspectingly get pinned down ( dog cuddled into submission ) sometimes for whatever reason people are immobile ( wfh)
Sometimes someone's cooking etc and theres huge amounts of residual heat.
In spite of being able to program the overall thermostat to cope with different needs, levels of sensitivity and adjust the room ones etc it is never a perfect temperature for all people in all places in the house.
That would be a whole different level of technology. Not impossible but currently unlikely. ( Im happy to beta test if any one is developing this) In the meantime its living on my own or compromising. Still much better than being limited to sitting around a fire until the veins in your legs go pink and you get backache from it being cold in the shadows which I remember quite well from my childhood.
