Gas CH 42.5p/hour

Horseunderwater

I have been checking my Gas usage over past week and due to my illness I need CH on a bit more at present.

It is on for 17 hours at 21deg C and we seem to have used £7.24 a day which works out at 42.5p an hour. Does anyone know how to get the 42.5p converted into KWHrs. We are on stand BG tariff of .04524p/kwh after first 2680 at .08065p/kwh. It is a pre payment meter.

I shall be playing around with temp and time on over next week.

Assuming there is no debt on the prepay meter, you are using approx 154kWh a day.

Over 17 hours that works out at approx 9kWh an hour.

The Tier 1 units(the 2,680@8.065p/kWh) cost an additional 26p a day.

No debt on meter.
Working on those figures my usage will be over 28k kwh's - that cannot be correct. BG stated I used 24246.53 kwh's between Nov 11-Nov 12 and that was when CH was on constant setting and not working well so was constantly trying to heat up the house all the time. Boiler and rads were full of iron oxide which was cleaned out at the end of December 11 - we went from boiler on at high burner to the lowest setting and even that was too hot. We have since had a new TRV fitted to a non working rad and a new Y valve diverter unit so that water and heating divert as they are meant to. It has been programmed and runs on that now - not constant so we should be using far less overall. And if I added 26p per day that would be 44p/hr a day spent on heating/gas usage. And that comes out at £7.48 a day not the £7.24 we did use? When I did what I thought was the calculation it came to 9.3943 kwh's. So it would seem that I kind of got it right - It just looked so odd that I wanted someone to tell me what they worked it out to see if I'd done it right. Today it will be 20deg over the 17 hours. We shall see if that lowers it a bit.

What is 28kWh??

You pay for 2680kWh pa at 8.065p/kWh. That is 7.3kWh a day so 59p for those Tier 1 units.(which is 26p more that 7.3 Tier 2 units @4.524p)

So £7.24 minus 26p = £6.98.

£6.98 divided by 4.524p = 154kWh a day.

So for 17 hours that is 9kWh a day

9kW heating power on average, not 9kWh, in case the above typo confuses.

Thanks.

Not sure I understand the rest of your post. The typo was putting 'day' instead of 'hour'

i.e. £7.24 at his rates is 154kWh a day. So for the 17 hours the average consumption is 9kWh an hour.

Had already realised that there was a typo.
10 hours into my 20 deg day now. £3.54 so far - so it should be around £6.018 by days end. That also includes a small amount used on a gas hob to cook one meal - small ring at low setting only for 1 1/4 hrs.
So just popping the Thermostat down 1 degree seems to make lots of difference. Well over a pound. Will know proper total later after midnight.

Work out how much every room needs to heat it using a heat calculator

http://www.qvsdirect.com/kW-Heating-Calculator-p-50.html

For example, if you have a room which requires 4kw of heat, and you are awake and using it for 12 hours a day, then you will need to budget 4kw x 12 hours = 48kw/h in which to heat it adequately.

So if your gas costs 4.5p per kw/h then 4.5 x 48 = £2.16

So you should budget £2.16 to heat that room 'worst case' and anything less should be considered a bonus.

Then add up all of the rooms you are heating, and you'll have a rough guide of what you should be paying and how far out the actual cost is.

Of course its not 100% perfect, because insulation, thermostat settings, boiler efficiency ratings and outside temperature will also play a role, but I wouldn't be surprised if it turned out to be close.

Use a comparison site to see if you can save yourself some money by switching, which you can almost certainly do.

As long as you don't owe more than £500 on the meter, then you will be able to switch and save. (Edit: just read a later post where you confirm no debt on the meter, so switching will not be an issue :beer:)

e.g. if you use less than 19,000 kWh per year (the average is just 16,500kWh) then Ebico would even be cheaper for you at 5.06p/kWh (and no 2 tier pricing or daily standing charge)

You could probably get a cheaper price than Ebico, especially if you are a high user. A comparison site will hold all the answers

Other things you can do are:
Turn the thermostat down a degree or two.
Turn off the upstairs rads during the day.
Set all your rads as low as you can tolerate.

Fully aware of all that. Hubby is mostly upstairs and I am mostly downstairs. I have an incurable illness and the medications I am taking for that - make me very cold at certain times of the day. House is old and can be drafty. Wind blows across fens with not much to stop it or soften it. We are in process of getting a loan/grant via council, but that takes time. Nothing will happen until new year at earliest. I only qualify now because I am on ESA income related and in support group. Draft excluders have been fitted over past year.
I also currently have cellulitis in both legs - so am in constant pain. Have just begun 4th antibiotics course of pills. It is slow to go as I am also diabetic - which means any infection takes a long time to go. I wish I was not so ill, but that's life.
