To ask how cold your house gets with no heating?

[JaceLancs]

Quite a few threads recently and I am wondering how cold peoples houses get without heating
Im in the damp north west and quite near the coast so can be windy
3 bed semi built in the 60s
deep loft insulation plus boarded out, cavity wall insulation and double glazed windows and doors
We use draft excluders and thick curtains including door curtain
Without any heating on at all it rarely gets below 12, my old boiler had no thermostat and could only set by timer so we used to leave switched off between bonfire night and Easter or 1st April if a late Easter and although I have a newer boiler now still do same
DP lives in a terrace house further inland and has no heating at all - he benefits from either side and it rarely drops below 9-10

Heating hasn't been on yet today, it's currently 15c. A few evenings ago it went do to 11.5c it was really cold, so we're now putting the heating on for a few hours each evening.

NW, 30's house, double glazed, cavity wall insulation.

Somerset - poorly insulated 10 year old house. I live right on the edge of a valley so winds from the east slap right into us. We went away last Christmas and I popped the heating onto its frost setting, when we came back in after a week it was 13 Celsius. At the moment it is about 15 in the morning after heating is off all night and after popping it in for a half hour in the morning it hovers at around 17 all day.

Amazed at how many houses are so warm without heating. We’ve had a really damp wet autumn so far in the north west ( at least that’s all I remember) we had to put the heat on short bursts daily as the house and everything in it was cold and felt damp. Even ventilating it’s high humidity outside cos it’s so wet!

But we’ve had drops in temp as low as 2 degrees so it has also needed the warmth. While it’s a warmer November the house does t feel the benefit from it! Our 30s semi even with newish insulation in the loft just doesn’t keep the heat in winter

My bedroom was 12 degrees one morning last week when I got up. We don’t have the heating on overnight but do set it to come on for an hour before the children get up and an hour upstairs before they go to bed. It was set on the timer again after the 12 degree morning .
We have a coal fire in the living room with a back boiler which has been lit almost every evening since the beginning of October . We couldn’t manage without it . We all congregate in the living room in winter whereas in the summer we’re all over the house . There’s a small oil filled radiator in the study for doing homeworks etc or if someone wants to watch something on their tablet etc.

If you left it all the time with no heating it would reach ambient temperature- that's below freezing if it's that cold outside

That's just physics

How long it take to get there depends on insulation

Bodies gadgets and cooking will lift it a little

Well everyone is different.
We heat our house for an hour or so if it drops below 19, so it tends to be around 21 in the day. Otherwise I can't maintain heat due to poor circulation, I already have other health issues.

Maybe 14 degrees lowest - a 1960s purpose built flat. Don’t have heating on much

400 year old house in the Home Counties. It’s 15.5 on the thermostat at the moment and we haven't had the heating on at all today yet. We will switch it on for an hour or two this evening though. It’s generally a fairly warm house as long as we don’t let it get too cold - if we go away for a few days it really feels freezing as soon as we step through the door, but never into single figures.

We‘ve also got an open fire (bad, I know) and we tend to light that on really cold evenings.

Once upon a time (like, last year….) we'd just put the heating on without a second thought as soon as we felt a bit chilly. That feels an impossibility now ☹️

You've quoted the wrong person @walkinwardrobe I'm not the author of the paragraph in bold font.

Today it was 11 degrees outside so am not surprised it’s 15 inside
Yes to an earlier poster there is the body heat of house occupants including pets - cooking warmth, washing/drying, use of lighting and other electrical appliances all of which warns things up

Ours is 9 to 10 degrees

we are not putting the heating on yet and are managing with wearable blankets
