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?

One of the BEST bits about being a single parent is controlling the thermostat temperature!! Oh the freedom is bliss

Croakymccroakyvoice · 18/10/2025 16:15

18 is perfect but having heating on and windows open is madness. Your bills must be sky high!

2025VibeandThrive · 18/10/2025 16:18

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

BlissfullyBlue · 18/10/2025 16:19

What are you all wearing? Eg are you cold despite wearing thermals and jumpers? Is he hot despite wearing a t-shirt and shorts?

In any event would strongly recommend a heated throw. I use one to avoid putting the heating on and it is so toasty whether or not the windows are open. It creates the ideal combo of fresh air and cosiness.

He’s in T-shirt and shorts and too warm, I’m in joggers, T-shirt and oodie and cold 🤦🏻‍♀️ I’ll look into a heated throw!

18 is quite toasty, I tend to keep it at 16. We all have electric blankets which has turned out to be a brilliant way of getting the children to go to bed, if not sleep.
I keep the windows

I agree,15 is pretty perfect to me.
As the temp outside is still 14 here the heating won’t be on yet for hopefully several weeks.

AhBiscuits · 18/10/2025 16:23

Ours is set at 20 and still only turned itself on once so far this year. I can't stand being cold.

Sarah2891 · 18/10/2025 16:23

18 is fine. I wouldn't want it any lower, and I'm someone who feels hot very easily.

Ihateslugs · 18/10/2025 16:25

I used to have mine set at 18° as background heat then turn it up if I was sitting around and felt cold. Visitors and family found that too cold for them so I had to remember to turn it up before they came. However, the last couple of years I’ve been feeling cold myself, possibly as I’m getting older and also have mobility problems which mean I move around a lot less. So I’ve had to boost the heating a few times this year so I’ve now turned the thermostat up to 20° and even that was still chilly the other evening.

Luckily I can afford the extra costs as I no longer have a mortgage and my monthly expenses are not too bad so I’m not really worrying about it. My bungalow has had damp problems in the past and I still get a bit of condensation despite some preventative work I’ve had done so I need to keep the structure warm to prevent issues.

Viviennemary · 18/10/2025 16:25

I'd be freezing at 18°. Try to keep it not higher than 21.5.

JLou08 · 18/10/2025 16:27

18 is fine in winter. I'd feel the house was too stuffy if the heating had been on by now, it's not been cold yet where I live. I'd be opening windows too if someone put the heating on.

15 seems really cold to me. The minimum recommended temperature for your average workplace(That doesn’t involve strenuous work) is 16.

Ohtodostarjumps · 18/10/2025 16:28

Well, I’m not in your club. 21C and preferably snuggled in with a golden retriever.

ConBatulations · 18/10/2025 16:30

18 is the NHS recommended indoor temperature. 16 is the minimum workplace temperature unless doing physical work. 20-21 is a typical target temperature. Have you checked the accuracy of your thermostat?

Shock ventilation once or twice a day would be better than leaving all your windows open and wasting the heating especially if your radiators are under the windows.

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.

youalright · 18/10/2025 16:37

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

writingsonthewall · 18/10/2025 16:40

18 is pretty cold! I put mine to 20 but don’t have it on for long periods. Just half an hour to take the chill off

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

KookyRoseCrab · 18/10/2025 16:46

I’m a 22degrees person , husband walks around in shorts and T-shirt and I have my heated throw on too .

The research found exposure to temperatures of 18°C or below were associated with negative effects on health including those related to heart and lung health, sleep, physical performance and general health."

Ours is set to 15 or 16 because we have large dogs with a double coat and anything warmer isn't fair to them. We never argue about it and we tell visitors to wear warm clothes when they come to us.

Thatpastalife · 18/10/2025 16:51

I’m amazed by how hardy some of you are, I like it at 21c/22c and still have a throw I sit under, but that is more I'm the evening when I’m not moving around. Feeling a bit frivolous now… 😂.
