How much gas are people using on these chilly days?
Much more than we should be currently, I've identified an issue with the the plumbing which means the boiler can't get into condensing mode and has to work harder than it should to get heat to radiators in the original part of the system. Not entirely our plumbers fault as there is clearly an underfloor issue in the existing system that was exposed when the new and old were spliced together... and not identified previously as, well, the heating wasn't on!

Interesting - must be costing a fair bit. We’ve used 670kwh month to date, which is approx 50kwh per day. Only two of us in the house, but we both work from home. In years gone by we’d have the heating on all day and hardly think anything of it. Now we have a blast for about an hour in the morning, an hour around lunchtime, and then a couple of hours in the evening - but we do supplement that with a wood-burner in the living room from around 6pm….I guess if I could measure the energy from burning the logs it may be similar to your usage.
It is costing a fair bit, but I'm not sure what else to do. Mrs B feels the cold, so I freeze all day so she can have some warmth in the evening!

Our house just doesn't hold the heat as things stand, so "a blast of an hour" really does very little, certainly downstairs anyway. The upstairs warms up far quicker.

When the heating came on at 5:30 this morning, it was 13.6 degrees in my son's room where the Hive thermostat is. It would probably have been a couple of degrees cooler downstairs at the same time. When it went off at 8:00 it had reached 16.9 degrees. The radiators gave out some more heat, the temperature peaked at 17.2 degrees and it's now on the way down again.

This was yesterday's roller-coaster!

Would it make a difference to not let it go off for those two short periods in the evening ? An hour in the morning is sufficient for us to get ready for work and yesterday we managed just 4 hours in the evening (5.15 to 9.15) with no gaps. We also have Hive and Ovo which at least takes away nasty bill surprises. As to what you can do, my guess is not much because you have kids. You don’t have the option of staying in one room and benefitting from the door not constantly being opened. We have a log burner for supplementary heat but have only had a couple of fires this winter so far as that’s also not cheap. We did take delivery recently of a large amount of logs though so it’s always a back up. Our biggest luxury this Christmas will be a full house of family with the heating and log burner on all day.

I've got cavity wall insulation booked in for the beginning of January and I was thinking about getting a window company around to take a look as I think we're in the same situation as you.

Our bedroom (at the front downstairs if you can remember your visit) is the coldest room in the house. My side of the bed is by the (also bay) window and I can feel cold air coming round the blinds every night.

I had read something that suggested that the window panes themselves being cold is a good indication of the windows working, but I'm not so sure. At my mum's house, which is always toasty warm for far less gas usage, her windows aren't freezing to the touch like ours are.
The basic rule of thermodynamics means the window panes want to be at the same temperature as the room and they are attracting the energy to do so, so agree with you. I've just opened a window as I type and the outside pane is significantly colder than the inside - which is what you'd expect. The whole idea of the double bit of glazing is to separate the 2 panes so that one is outside temp, the other inside. My thoughts are that it isn't necessarily the sealed units that are the problem in my case, it is the frames and seals around the units that cold air is penetrating and getting sucked indoors - like you, sit next to the bay window and you can feel a proper draught of air.

What type of CWI are you going for?

I've been researching the closed cell polyurethane foams, namely:
BASF WallTite
Isothane Technitherm

Considerably more expensive than typical CWI. An example would be for a typical fluff installation £1k, graphite coated beads I'd be looking at £2.5k, Technitherm £7k. :eek:

However, the PU foams have a considerable performance advantaged, can actually be used in flood risk situations, act as wall stablisation and can replace the need for wall ties, air tight but breathable.

The red flag for me is being confident the external brickwork / masonry is in excellent condition with no pointing issues, cracks or defects. The cavity then has to be thoroughly checked that it is clear of debris, and that isn't just their inspection scope once in each elevation, it needs to be done at regular intervals to be sure no broken bricks, bits of mortar etc. fell into the cavity during construction or other works. You also want to make sure the wall ties don't need doing. If going beads or fluff, you don't want to be replacing those after as when they drill for the replacement tie rod, the back of the brick always pops out and will just sit in the insulation getting cold and damp.

I have a four bedroom mid terrace in Brighton.
Four showers a day plus washing machine on twice a day (three ladies in house creates loads of washing)
We put the heating on low nineteen days ago mostly for drying said washing but also for warmth.
I put a reading in to Eon Next just to see what we have used in that time.
£150.88 for gas & £108.64 for electric = £259.52 - £67.00 energy discount.
= £192.52 divided by nineteen days = £10.13 a day for heating/cooking and hot water.
Without the discount it would be £13.65 a day.

My recommendation is to go outside for a bit..preferably stand in the shade and easterly breeze then when you pop back in the house feels so much warmer…you’ve not been charged for this advice
Exactly what happens on my dog walks. Sat freezing indoors, dog nudges my leg, reluctantly go on a walk toward the downs, get back home and strip off because it feels so warm!

We have a modernish house with reasonable quality double glazing. On cold days we get condensation on the *outside* of our windows because they are doing so well at preventing heat escaping to the outer face.

To be honest, the word "blast" was a bit of an exaggeration! We live in a 300 year old cottage with poor insulation. It's bloody cold unless we have the heating on for a sustained period. And not long after my previous post, Mrs Jim in the West decided that things have got too miserable, and she'd much rather go without a holiday than suffer in the cold all day. Hence, as from today, we'll have the central heating on most of the day! In reality we're lucky that we CAN afford to heat the house well AND take a few holidays a year...it's just a natural instinct, I think, to want to preserve energy (and money) wherever possible.

I put my newly-installed heaters on 24 hour FROST (permafrost?) mode before I departed for warmer climes last monday. Be interesting to see what they've done while I've been away. Not very much I suspect on account of thick stone walls and dubious loft insulation that consists almost entirely of historical strata of squirrel shit :down:
Well, finally made it home yesterday after a journey of Trains, Planes And Automobiles proportions. Can report that Duplex FROST Mode is near enough useless vs sub-zero temperatures in a 150 year old building with thick stone walls. Might as well not have bothered. Duplex ECO Mode, on the other hand, that I've now tried for the first time, seems to do the trick admirably. 18 degrees round the clock. It's teeshirt weather at Hark Towers. Luvverly! Lord alone knows how much the heating bill will be, but we'll worry about that one later eh?

Are you sure you’re Scottish ?
 






Our 2-bed semi (built in 2014) seems to be pretty efficient.

Put heating on for the first time a few weeks ago (mid-November) and been getting away with 1 hour heating in the morning and 1 hour early evening. A couple of days in the last week we've pressed the button for an additional hour at lunchtime (both work from home).

Indoor temp ranges from around 17º to 19.5º despite it being 0º outside for the last week.

Thermostat is next to the front door and I've noticed light and a cold draught around the front door frame, so ordered some draught excluding tape to pack out the gap and hopefully improve things further.

Have got the trickle vents open still on a couple of the windows, but may close those.

Still no heating bar using it for 1-2 hours per week to dry washing and dry the air/any condensation. Have used the wood burner 4 or 5 times this winter when entertaining -but logs aren’t cheap either! Need them to last until March. When I’m working from home, wrap up really warm. Mate wouldn’t believe when I was on a Zoom call with him the other day, I was sitting in a house that was 10 degrees - had to show him the thermostat 😂

I’ve sort of got used to it - As long as it’s dry and not draughty, it’s manageable with slippers, fingerless gloves etc and moving about regularly. I’ve always been a ‘no-central-heating’ type person because I find it makes the air stuffy. Tbh, have been far colder staying in Scotland in the middle of winter. It’s playing havoc with my asthma though. Ultimately, not only helpful on the pocket but kid myself I am helping the environment.

(I don’t have young children or pets at home so just as well but if I did, I certainly wouldn’t subject them to living in such a cold indoor environment)

The biggest irritation is that a cuppa stays hot for only about 60 seconds!

Well I have an old uninsulated stone cottage and can’t afford the extortionate fuel costs - but thanks for the advice - I wasn’t aware the cold could effect my health or damp air, effect the fabric of my home 🙂
I would recommend making thorough checks for mould. We also have an old stone home and before we sparingly started putting the heating on in late November noticed patches of mould on fabrics, place mats, a bed frame, one window frame and a wall of a shower room. Only small patches as we got it in time but with the toddler that died being all over the news at the time it seemed prudent to check. Shortly afterwards the heating went on for short periods and the mould hasn’t re-occurred.
