Do you leave the heating on or off at night
I live in a flat in London. During the night I turn the heating off
and then back on around 12:00 Pm. we set it to around 22 we love to sit
with short sleeve.
It takes the flat two and half hours to get from 17 to 22.
A friend told me it will be better to turn it down to 19 at night and
not to turn off because the walls are getting could during the night
when the heating is off and then it take a lot of time to worm the flat
back on.
I dint know what about you but I live in London and I remember that 10
years ago it was much colder and then we use to leave the heating on,
but now in our days with global worming the outside temperature is 7
degrees during the day. This is not so cold as it use to be 10 years
ago.
So should I keep my wall's worm at night?

What do you mean by 12pm 1200hrs or 0001 hrs?

It all depends on how well insulated your walls are.
Modern walls are well insulated old ones are *not*.
How old is your flat and have the cavities been filled?
Well insulated walls store *lots* of heat so you can rely on them to keep
the flat warm overnight, so you do not need to keep the heating on/turned
down overnight. Poorly insulated walls less so.

What temperature does the flat fall to when it freezes outside at night?

We turn ours off becaue we don't like to breathe in warm air, that's a
personal preference.

I live in a flat in London. During the night I turn the heating off
and then back on around 12:00 Pm. we set it to around 22 we love to sit
with short sleeve.

Perhaps, but it's wasteful of energy (gas or electricity) and more expensive
than putting on a jumper.

Ek! I couldn't bear that temperature :-)

It depends on your preferences, how much you care about global warming and
how much moiney you want to spend on fuel.

If your walls have worm you have far more serious problems to worry about
than leaving the heating on or not.

There's the problem. Your heating system is atrocious. Maybe also the
flat has no insulation anywhere. Once the heating's fixed theres no
reason to leave it on overnight. Until then you'll just have to time
the CH to come on 2.5hrs before you want it upto temp. Oh, and reduce
22 to 21 or 20. You're probably only wanting 22 because you've sat
there for so long in the cool.

Not necessarily. My house takes about 4-5 hours to go from 17 to
22...but conversely it takes all night and most of the following day to
drop back from 22 to 17...its a very big screed floor with UFH...and BIG
brick chimneys..must be several hundred tons of concrete and masonry
inside it.

So yours doesnt drop from 22 to 17 each day. If the temp drop you had
took 2.5hrs to warm up every morning, there would be a problem in that
the heating has to be set to come on 2.5hrs before wanted, resulting in
**** poor energy performance. I think thats a problem. I sure wouldnt
want this place running like that.

I had cavity wall insulation and double glazing installed this year so only
need to have the CH on in really cold weather. The HW/CH timer is set as
follows:
ON at 6am, OFF at 9am, ON at 5pm, OFF at 10pm. A lot of the time the CH
isn't on as the air temperature is above the thermostat setting (20
degrees). Two and half hours to get from 17 to 22 sounds like you have poor
insulation and/or a poor CH system. You could take meter readings, run it
for a week on 24 hours a day, take meter readings, run it for a week on
daytime only, take meter readings, and work out which is cheaper, but
outside temperature changes will affect the accuracy of this.

It is possible to construct scenarios where it isn't..see thread about a
month ago.

Boilers that are inefficient at peak output being the simplest one.

Not necessarily.

Given that the criterion is that the room temperature should be at a
certain level between specific times:

In the case of a modern building of low thermal mass and good
insulation, it probably is.

In the case of an old building with high thermal mass, the heating may
have to be switched on earlier in order to achieve the required
temperature at the start of the required time, or overdesigned to
produce a faster warm-up. The latter may have a tendency to cause
temperature overshoot leading to less comfort and higher energy use.

Temperature set back may well be the most cost effective and least
expensive way overall to achieve the required result.

Even so, I don't remember my Israeli friends mentioning snow so I suppose
it's fairly unusual? Mind you, most of them are in Tel Aviv :-)
