To think that 17 degrees is not warm enough?

Staying with a family member who is refusing to agree that 17 degrees in a drafty living room is too cold!! I have a small child here with me and the said family member decided to sleep with the window open as they like the breeze. They also do not like to shut their bedroom doors so draft under our door into the ‘make shift’ bedroom all night. We are in England and it’s freezing at the moment. I am fuming and freezing but don’t want to ruin the day.

15c here heating came on at 8. But dh is a hot person so not many radiators on. We have guests today for lunch they like heat. I want to wear a dress rather than layers and a blanket. So I bloody hope it warms up.

Indoors? I would be mortified if I was making my guests wear fluffy hat indoors because I was too stingy to put the heating on.

It isn’t stinginess. I don’t like the sweatiness of indoor heating. I find 17 plus a nice fluffy jumper comfier.

Do you heat the house for friends and family?

Nope but they know, don't care and get a hot water bottle and a blanket. As well as not being able to bear it, I couldn't afford the bill anyway. Just keeping it at 14° for an hour or 2 in the morning and about 4 hours at night costs around £3 a day. I can't really go above £90 a month just for heating.

Yes I suppose that's true, I do put the heating on for the oldies and no I wouldn't expect guests to wear hats 😂. Saying that I don't think 17 is hat temperature!

So you would tell guests to wear fluffy hats if they were cold? You can of course do what feels best when alone.

Notmyreality · 25/12/2025 09:21

Really shit and inconsiderate of your hosts. Standard “room temperature” is defined at 20 deg for a reason.

arethereanyleftatall · 25/12/2025 09:21

The answers here are interesting in that many who like it 18+, think that if their host doesn’t accommodate that, they’re being a shit host. Surely that works both ways?!? Why do the people who like it hotter trump those who like it colder?

I’m in Mallorca and my house is currently 17 with no heating on at all today and it’s fine. We usually just heat with a log burner and don’t put the central heating on.

So just plain old selfishness then? Its
not about you when you have guests over. Your job is to make them feel comfortable.

Nannyfannybanny · 25/12/2025 09:22

It's not a case of being stingy, everyone is different. Both my neighbours have their heating in the 20s and wearing t shirts all year. All our living rooms face south..it can be frosty outside, but if it's sunny it's fine with no heating on in there. I am 75, and most comfortable with single figures at night..I also like the bedroom window open a little. There is a couple of dogs there The heating goes off when we go out. It's horrible if you have asthma,dries your skin out. My uncle who is in his 90s,big detached bungalow,has his heating at 16c. Very fit and still looks after 300 foot of garden.

17 surely isn’t fluffy hat temperature?

It is a case of being stingy when you have guests over and refuse to consider their needs. Stingy, selfish and inconsiderate.

Ok. So if your house was at 20, and you had a guest over who found that uncomfortably hot, would you turn it down to 16 for them?

cramptramp · 25/12/2025 09:24

It’s warm enough for me but if you’re cold it’s no fun. Can you put your coats on so you’re warmer and they take the hint.

It is cold today - I opened the door to go to the bin earlier and it's 2 degrees here. I would say 18-20 is ideal on a day like this.

18 was too cold for me. I woke up to that temperature in my bedroom and I was freezing (I have very short hair and it makes a bit difference). I have it on 21 now and that's lush.

Itsallabouttea · 25/12/2025 09:27

Like some PPs my house is edwardian with no cavity walls. It will just about get to 18 if the heating has been running all day but it struggles if the weather is really cold. I know some people would find this too cold but there's nothing I can do about it, we've already insulated everything we possibly can. I also now find many buildings too hot and stuffy so you definitely get used to it

I'm with your family member. I love a cool breeze at night and hate sitting in a stuffy house.

Funnywonder · 25/12/2025 09:28

We have ours set at 16 in the daytime. It rarely ever kicks in, even when it’s very cold outside, as our house seems to hold the heat. Then it’s set to 18 for a few hours in the evening. It cuts out at 18.5. Works ok for us, but I know some people who have both cooler and much hotter preferences. 17 would be ok for me provided I was wearing a warm cardigan (which I usually do.) My teenagers never complain of being cold, even though their bedrooms are in the loft and therefore colder. They don’t seem to notice. We put electric radiators in their rooms for an extra boost and they rarely use them.

Isobel201 · 25/12/2025 09:28

I keep the rooms during the day at 18 degrees, and during the night as well. Then the heating comes on for a couple of hours in the mornings and evenings up to 21 whilst I'm pottering about in my nighty and dressing gown.

I set my house to 20 when guests are here, luckily it heats up very quick so never a problem. But normally I have 18 in the day and 16 at night. I cannot stand sleeping in the warm! I loooove the cold air on my face as I’m warm under the duvet.

Regardless, it’s very bad from to refuse to change the temperature after a guests tells you they’re too cold.

16 at night is terribly warm, don’t you wake up with a headache and dry mouth?

16 or 17 in the day is stingy, I wouldn’t be able to cope. I don’t have much fat on my bones! I’d be ok if a host had forewarned me that their house struggled to get past that cos it was old so I’d need to bring proper wool jumpers and thermal layers and real sheepskin slippers or something. But lots of people don’t have those as their own house is naturally warm so they buy whatever jumper they like the look of without considering the material. Acrylic jumpers don’t warm you up effectively and some people wear thinner layers than I would in winter and would feel cold in a cooler house. So hosts need to warn their guests of this.

but to not say anything, and then when their guests say they’re cold, to refuse to turn the heating up is just poor hosting. Who wants their guests to be miserable it’s so odd and NastY if you can afford to buy just won’t.

and if you can’t afford to then you need to say and have forewarned them it will be cold. If I were a guest I would even pay some money towards heating for that month just so I was comfy

17 is below the nhs and who guidelines for health for your lungs

you can’t put a jumper on your lungs

Well my lungs seem to disagree. I don't get asthma symptoms if I stay cool but above 20 I start to get a tight chest. Our house is at 17 because that is comfortable for me.
