Have you put your heating on yet?

Our house seemed to take a lot of warming up this morning vs other mornings - even after the heating being on for 90 mins it was still only 16C in our bedroom and I really feel the cold. No idea why it was so bad, every way I could check the outside temp shows it showed +1C, although it was quite frosty this morning.
Have to be up earlyish tomorrow and I'm thinking of just leaving the heating on.
I left the heating on last night - backed the temps (on Tado's) down to 18C overnight. Normally 21C. Was perfectly comfortable getting up this morning. Have to be up earlyish tomorrow and I'm thinking of just leaving the heating on.
Used quite a lot of gas though - 112kW, normally on a coldish day we'd be 70ish. Did reheat the hot water after granddaughter's bath last night too, which wouldn't normally do in the evening.
Annoyingly the rad in our bedroom in the NE corner of the house cycled a lot and it's the one rad that's noisy with expansion and contraction.
Be interesting to see what today's use is without the boiler having to run at for a few hours at a high output to warm the place up.
Today I'm pretty sure my gas usage will be higher than it would be with timed heating cycles because today is 5 deg warmer than the last two days and when it is slightly warmer all day heating with set backs does use more energy
If we have a really prolonged cold spell I might try overnight heating again.
I got mine not to come on since 5pm last night so far I've used 32.6kWh
Taking coldest room from 16.3 to 19.3 between 6am and 3pm!
Yesterday midnight to 5pm 44.9kWh but that kept it at 19c all night then 20c during the day
But today was also warmer than yesterday 4kWh/HDD yesterday will see what it works out at at midnight
Seems 3.3kWh/hdd

What is a reasonable amount of time to warm up?
Obviously it's very cold this morning (-5) but we were only seeing ~17.4 degrees after 2h20m of heating. Normal wet system.
I recall British Gas many years ago having a spec for retro-fit CH into houses and the warm up time to reach the design temp was 24hrs!Obviously it's very cold this morning (-5) but we were only seeing ~17.4 degrees after 2h20m of heating. Normal wet system.
12 degrees in my bedroom this morning when I woke up. Felt surprisingly ok. Haven't had the heating on as it's electric and costs a bloody fortune. Usually burn coal at this time of year but I had 4 months off work due to injury and couldn't afford to buy the usual pallet load, so I'm eking my supplies out by heating at weekends.
Quick and dirty table
Outside temp -7
Heating went off at 0830 cos we left for work

I'm up 1c in about 90 minutes 18.5-19.5 39c flow -3.3 outside to -2.8at the end of that time
Used about 6kw over that period now sat at 3.92kWh

Timber frame housing isn't a popular construction method here on pistonheads but when we built brand new 9 years ago we went timber frame. We had 4 years in a traditional double brick new build followed by 5 years in a timber frame new build and now 9 years in this house, where we went timber frame.Obviously it's very cold this morning (-5) but we were only seeing ~17.4 degrees after 2h20m of heating.

See how quick it heats up. Thats a big benefit (there are negatives too, sound traveling much more easily within the house for example)
Times are 9:23, 9:45 and 9:59.
For context. Minus 3 outside and snowing
Took this pic from my build thread to give you an idea of construction method. Very basic, stud wall, wooly insulation behind in the frame, air gap,concrete breeze block and grey render on the breeze blocks.
Considering that ceiling is about 14ft high, and the downstairs ceilings are all 9ft high, it heats that area fast (L shape room, sunroom into kitchen living area and that's where those thermostat readings are coming from)
I've got a build thread which I can link to if anyone wants to have a nosey around how it was built but in summary, in our previous timber frame house, the chill is out of the air in about 10 mins and warm shortly after, so it was an easy decision to go timber frame again. Stays cool in summer and heating the house in winter is almost like an on off switch.
Our house is a 20 year old mix of block, partition walls, dry lining....
With big rads, the CH will raise the air temperature quite quickly, but heat is stil soaking into the walls for hours I think.
The lounge to go from 'freezing' to 'bearable' in 20 minutes or so?
Where we've got dry-lines cavity walls, I suppose the inner leaf of the cavity wall might get cold, and the room air will take a long time to get it back to a stable temperature, because it's insulated by the dry lining plasterboard/air gap.
It's rare or us to have the heating on all day, but when we do, it's noticeable the heating works less hard in the evening.
An old house made of stone, or a modern house designed to have a high heat capacity, could take days to get near 'steady state'.
Some modern houses are deliberately designed that way, for isntance if you live in the desert where it's hot in the day but cold at night it's a good idea.

For those of you that sound like you've got the heating on a lot (relatively) can I ask what your monthly energy DD is for the year? I know it's tricky but, for example, in our place, if we have the heating on for about 7 hours a day (morning and evening), with electricity for an average house, we hit nearly £17 yesterday for total energy cost (based on GSH @ 7.1p/kwh) and its not as if we have a warm house with the ambient temp as it is - last month the month cost was £380 and that's with a multi fuel stove running from 4pm to 10pm which I probably spend £800 a year on fuel.
I appreciate comparing apples (small house) and pears(big house) and speedboats (income) doesn't really server a purpose but I'm interested in what people really balk at when they see how much bills hit?

I'm a complete tight wad. My DD (electric only) is £45 a month (1bed end terrace). I'm electric only, but use a log burner as much as possible, and shower at work. Annual usage is about 3,000kwhI appreciate comparing apples (small house) and pears(big house) and speedboats (income) doesn't really server a purpose but I'm interested in what people really balk at when they see how much bills hit?
For me
150sqm 4 bed 2 people occupied 24x7 heated to 19c (actually hits 20 ish)
6am to 5pm then setback temp of about 18c overnight
Yesterday I was burning for about 17.5 hours and used 64.3kw 7.42p £4.77
But in tracker I paid £2.46
electric yesterday 10.6kw £3.03 on tracker it was £1.71
i pay £100 a month for gas and elec
