How cold is your house without the heating on?

[Notcontent]

I am in a small Victorian terrace. Had new windows, new boiler and some insulation put in recently ( limited by nature of property). I am a bit disappointed by results. Downstairs area has an extension and is better insulated (some new walls) so if I heat that area it seems to retain heat for longer. Upstairs is pretty chilly. I put heating on at bedtime yesterday for a couple of hours and it was about 16.5. No heating on since then and it’s 14 degrees upstairs. I am in London by the way and outside it’s 5 degrees.

is that to be expected in an older house?

1790s, single-glazed, weatherboarded, listed cottage. No heating for exactly a week (holiday cottage - empty, curtains open) and dropped to 13 degrees. I'm surprised at how well it's performed compared to some of the more modern houses on this thread. End terrace so that might help. Was there cleaning for tomorrow's guests this morning and put heating on. Cottage was 18 degrees when I turned heating off. It is now 16 degrees (9 hours later).

To add - it's about 2 degrees outside at the moment, the heating has been off since 5pm (when it was on for an hour) and it's 16 degrees inside.

I'm in bed under the duvet and feel perfectly warm in a t-shirt with the window open.

1980’s detached, no double glazing. It would be 7 or 8 degrees with no heating here. I can’t afford it but I’ve had to set my thermostat to 16 and let it come on when it dips below that. It’s not toasty but it’s warmer than 7 degrees. It seems to be more effective at keeping the house warm ish than putting it on for a couple of hours each morning and evening, it’s not on much more than that during the day/night but I guess it’s working less yo keep it up to temperature.
I have thick curtains at the front door, all doors upstairs shut during the day. Many many blankets!!

We have a pretty efficient newish build with a lot of insulation. We heat to 17.5 in the morning. The house has been dropping to 14.5 at the lowest by the time we get home at tea time.

I'm not sure what you expect? Of course it will be cold without the heating, and leave it off long enough and inside will just be a couple degrees above outside. Something has to be generating heat for the insulation to have any affect.
I have never tried it as I have my heat on all the time, set at 18. Thermostat is in the warmest room downstairs so upstairs is always colder. It doesn't cost that much more to run and as I'm here all day it makes sense to me.

9-10 degrees at the moment indoors with outside temps of -1 to 3.

If I don’t heat at all all through the winter it will end up lower than 5. Lowest I’ve seen it so far is 3 degrees indoors.

Was 13 this morning... as we did the cooking and the oven was on etc, it rose to 14. So it roughly differs between 13-15..

1960s semi with recent cavity wall insulation. Heating on for an hour in the morning and 1.5 hours at teatime. It's usually 14 degrees here when we come home after school 🙁.

Our house was built in 2004, without heating on in the morning is 15 degrees atm. Not unbearable cold really, but still a bit chilly.

Growing up, we were never allowed the heating above 60f. Which is about 16.5c I think. I used to whack it up to 70 if my mum didn't notice.

11°. Ouch.

Great that you're getting the aluminium windows replaced, in the meantime could you try putting up clear polythene secondary 'glazing'? We did that on draughty single glazing in a previous house and it made a big difference.

12 degrees. It’s pretty miserable. I pop the heating on in the evening for a few hours and bring the house up to 18 degrees. I can already see that it’s costing me a fortune to do this though. I can’t believe we are having to worry so much about heating. Last year we were lovely and snug at 23 degrees.

Victorian stone terrace in South Wales here- we have the heating on a fair bit or the temp drops quite quickly. We end up at around 16 degrees overnight if we're lucky, and that's with having the heating on a fair amount in the daytime. If we left the heating off for 24 hours in todays weather (6 degrees) our house would drop to less than 10 degrees and we would also start to get damp. We keep the house at between 18-21 during the day, if we don't heat it to 21, in the room our thermostats in, at least once a day we end up with mildew on some of the external walls. So heating on it is!

12 degrees here now in our lounge.

Heating on today 9-10am

6-8pm

Outside is 3 degrees I think

Ours is a detached new build and heats up so quickly and retains heat really well.

But my parents live in a detached house built in the 60s and its noticeably colder. They have the heating on a lot more than we do too. I am chilly there a lot in a way I'm not at home.

1980’s shoebox, no central heating, it’s been 12 degrees all week.

Modern new build apartment in London, 20.5 all day dropped to 19 this evening, so well built and insulated I have never switched my heating on, I have been here for 3 years

Not my first time on one of these threads

Boiler on the blink, currently 19 in the living room (wood fire), 16 in the kitchen with a radiator on and and cooking going on. Upstairs is about 12 without heating, bathroom colder as it's on a corner, and 14 in our bedroom when it warms up - I put the radiator on an hour before bed. I turn it down when I go to sleep and leave on low overnight. We have cheap rates overnight and our electricity increase was capped at 4%. I'm sure we are saving a bloody fortune on gas (DD is 250 a month, though obviously the usage is higher in winter).

It's colder if we're both out and the fire isn't lit. I have to go out tomorrow and think I'll leave a radiator on. It's an old house with high ceilings so takes a while to warm up.

We bought one oil filled radiator for 65 euros and a friend lent us two more. And have a fan heater for the bathroom-fridge.

I cannot imagine letting it get lower than 18 if I had the choice.

Currently 1° outside. It's going to be a long week.

19° currently but next door appear to like their house like a sauna which helps ours... No heating on here yet. The kitchen I think is a bit lower but not particularly chilly prob 17°

14.0 right now. The heating will come on when it drops to 13.5, I think that's how I've set it.

We came back to 12C after leaving the heating on standby for two weeks (5 degrees). Outside temperatures were 4-14C
The other flat has centralized heating (19C for 3+3+4 hours a day) and is well insulated. It doesn’t go under about 15.

I live in a second floor 2 bedroom flat,built late 1950s. Without any heating on,it registered 16.4 degrees today. I've always thought that that sort of temperature would be comfortable,but bloody hell,I was SO cold!

Forget to say, outside temperature was reading 6 degrees C,but with wind chill factor felt like 4.

9 on Friday 🥶 heating engineer is popping in tomorrow. If he says we need a new boiler I can't afford it. So could be an interesting winter!
