    Concerned over electricity usage 8th Oct 17 at 7:21 PM
    Hello all.

    I'm concerned about what is using my electricity whilst at work. I use a pre-payment meter.

    I live alone in a two bedroom maisonette and when I go to work I come home and over £2 has been used each day. That may not sound a lot (?) but i'm using over £20 electricity per week including what I use in the evenings and I was speaking to a friend who spends more time in her home than I do mine and she spends £15 per fortnight! I've not even turned the heating on yet - I thought the amount I spent was normal until my friend told me her usage and then I look around the internet and it seems I am on the high side.

    Aside the fridge and freezer, the only other things I can think of are the DVD Recorder recording from my Sky Box (old Sky Box, not Sky+ or HD) and the boiler that are used in the day. Bear in mind I work fairly short days - around 7 hours from me leaving in the morning to me coming home later in the day.

    I'm thinking of avoiding recording on the DVD for one day to see what happens. Will it be cheaper to turn the boiler off when at work? I don't use hot water as soon as I get in but need it for my morning bath.

    I know their is a standing charge of £2.01 per week, but not per day! My KwH price is £14.09 and their is no debt.

    Dont worry about DVD players.

    How do you heat water? Electric shower? Electric cooker? These are what really use power.

    I don't have a cooker/oven - just a slow cooker, grill and hobs.

    Turn off your boiler after your bath and see what it does tomorrow.

    By electric boiler do you mean an immersion heater? (A copper cylinder possibly coated in foam) or an actual electric boiler. If it is the cylinder and it is turned on all day/night that would be what’s costing you.

    So, had it off today and rather than over £2 spent whilst at work - 14p! Wow.

    Now I know what it is that's doing it, rather than regretting what I have been doing, it's onwards and upwards and time to turn it off in the day.

    Now, how long do these immersion heaters tend to take to heat up fully, for a full bath. I appreciate they may all be different, but on average?

    I'm going to have to turn it on in the evening and also overnight so I have hot water for my bath in the morning and a bath in the evening plus washing up etc (or maybe i'll just go dirty in the evening )

    Have you got a single rate or peak/off peak tariff (like E7) check your leccy bill.

    If it's an E7 tariff, try setting the hot water heater on between 5-6 oclock in the morning and see how much hot water you have. If you are on an E7 tariff then it will cost you twice as much to heat the tank during the day or in the evening as it would if you heated it between midnight and seven am.

    You'll probably find that there's enough for a bath both in the morning and the evening, especially if you don't fill it to your chin.

    Do you really need two baths a day?. You could try showering although a shower will only save you money if you dont stand there for ages, limit it to five minutes maximum.

    A properly insulated hot water tank will remain hot for around 24 hours so make sure the insulation is in good condition and if necessary put another insulatiung jacked over the one thats already there. Just turn it on for an hour and if that's not enough then try for an hour an half.

    Start using water wisely. Dont rinse stuff (including your hands) under running water especially hot. Be aware that every time you turn on the hot tap to run off the cold until it's hot the the same amound of hot water sits in the pipework wasting energy. Save your washing up and only do it once a day.

    It's also worth turning stuff off at the wal when it not being used and change your lightbulbs to LEDs. Just asving £2 a week is 3100 a year.

    Start reading your meter weekly to find out where it's all going so you know how to save energy

    It's single rate - Rate 1 from EON.

    On gym days I take three - before and after gym and then the evening, non gym days, just two. I only do that as i'm OCD about personal hygiene but I can ignore the evening bath if need be, unless going out, but that's rare of an evening.

    I still had fairly hot water coming out of the tap when I came home - enough to wash dishes and more.

    I currently have energy saving bulbs - they aren't LED's, they are those spiral type ones.

    I'll start switching things off at the wall more. I do most things.

    I look at my meter each day now. I started becoming concerned when i'd been out and i'd lost £2 per day, every day. I was spending £3+ a day and that included no heating - today, after dinner etc I have spent a total of 57p so far.

    So I turned on the immersion for just over an hour in the evening and it cost approx 70p.

    I then turned it off and turned it back on overnight - 9 hours, and it cost approx 84p.

    Have had my bath, will be off to work and the immersion is off for the day - let's see how we go - i'll avoid a bath tonight and see what the days end total is (and tomorrow morning).

    Sadly I have no timer to ask it to switch on at 5am, so it has to be turned on before bed for my bath in the morning.

    By heating your water just before you use it, you will save a few watts of energy as all cylinders lose heat with the passage of time. The major driver of the cost you incur is therefore the cost of re-heating your cylinder each time that you draw a bath. It's basic physics. Here is a guide to the cost:

    £180+ per quarter without using any heating does not sound right to me

    An immersion heater is 3kW. If that really is costing you 70p for 1 hour, I suggest you start hitting the comparison websites - you can do a lot better than that!

    Edit: I just saw you say you pay 14.09p/kWh, so the above costs does sound wrong

    I turned it off after running my bath just to see what my meter says when I get home this evening.

    Going to play around for a week to see what the best way is.

    I had my PC and 1 light on as well, but don't think that takes up too much energy?

    So it was 70p to heat up immersion from cold plus my PC and light (low energy bulb), so it wasn't all immersion heater, but I imagine it was the majority of the 70p.

    You really need to check actually how much your leccy is costing you.Dont forget there'll also be a dailing standing cahrge of around 20-30p depending on what tariff you are on.

    As Footyguy says, an immersion heater is 3kw so for one hour you should use 3kwh times 14.09 = around 43p. so you really need to check if theres a debt on the meter that you are paying off.
    A PC will cost you around 50-100w depending on what sort it is. Even if you have it on for 10 hours you wont use much more than 14p. A Sky box will take around 14p a day unless it's an up do date one which are a bit more energy efficient.

    An average hot water tank will take around 6-7kwh to heat it from stone cold but unless you are swilling away a whole tank full every time there's usually some warm water left so it should be costing you less than 70-80p to reheat it.

    We can get away with heating our tank once a day for about an hour and a half and that gives us enough hot water for both of us to shower in the mornings and all our washing up and there's still enough hot water left to have another two showers if we wanted either in the evening or next day.

    I'd suggest that you use the showers at the gym and get your moneys worth out of the membership fees and save energy at home.

    Weekly standing charge is £2.01 - no debt on the machine - i've checked through the screens on the meter.

    Strangely, I had it on all night - 84p, had a bath and that was the lot this time - no extra for washing up this evening.

    Out at work today, 14p used, so it's saved a lot. Maybe I can not have a second bath today.

    I don't know if 2 or 3 baths a day is too much, but I don't use the gym showers as i'm OCD about hygiene and worry about catching something/previous person peeing in the shower - plus when I go the gym, I want to workout and get out of there ASAP.

    If you have 2-3 baths per day find out the cost of installing a shower which may pay for itself very quickly.

    Saved at least £1.50 yesterday by having one bath. Today one bath again, but re-heated water for 45 minutes so I can wash up. So far i've spent about £1.60 less, with around 4-4.5 hours to go until bed.

    Tomorrow I must have two baths - one before and one after gym.

    I'll keep trying different combinations throughout the week and look at the results. If any do save an amount of money whilst not making things tough for myself and/or make me worry about hygiene, than i'll make a new routine.

    Not sure why you need a bath before going to the gym - afterwards seems more sensible but that's just my opinion.

    However that said, at least you know how to save electricity even if you aren't happy about doing it

    Just to smell fresh at the gym - I know I will sweat anyway, but don't want to arrive smelling - maybe I won't smell, but it's just a fear of mine.

    I gym early in the morning, any time from 6am -9am, so it's my usual morning bath anyway.
