    Usage increased 50% in a year - how to track it dow 13th Jun 19 at 1:24 PM
    Hi

    I've determined our electricity usage has increased 50% year on year. Heating is gas so we can exclude that from the equation.

    May June last year we used 680 units
    May June this year we used 978 units

    Nothing has changed in the house in real terms.

    One 4K TV has been replaced with an OLED and an extra TV installed in the guest room (switched off)

    We've added an extra pump to the pond - but that alone wont be using that much power as its the same as two others we have.

    Other than that, nothing has changed electrically.

    How on earth do we go about working out which device has malfunctioned!

    even a cheap and cheerful pond pump will consume around 25-30 watts. Something a bit more meaty would be 50 plus.

    50watts for 24hrs is 1.2kwh x 365 = 438kwh. At 13p/kwh = 57 a year so it's worthwhile checking how much each item uses. Putting them on a timeswitch and only running them for 12 hours a day instead of 24 would halve their consumption

    We were horrified when we found tha tthe transformers for our electrically operated recliner chairs took a continuous 15watts each even when the chair wasn't operating.

    That reminds me of a treadmill I once encountered that consumed 40W when "off", but plugged in.

    The pumps are a definite likely suspect.

    I've worked out the old TV cost us 4.44 per day and the new one 9.20

    Well if that is the maximum then its less of an increase.

    Pond pumps:

    We have koi so we can't switch them off for 12 hours or we would have dead koi.

    We have always had three pond pumps.

    The issue isn't our high usage - I'm happy with that as that is what we use.

    The issue is in April almost overnight we went from circa 600kw per month to circa 1000kW per month - whilst the TV might account for 10% of that, there literally was nothing else new added.

    husband has been off since last June and hasn't suddenly been mainlining tea (we have quooker so no kettles meaning shouldn't have any peak)

    Ok, slightly confused because you referred to an additional pump. Doubly confused as I misunderstood your "May June" figures as for two months, not monthly. So my guesstimates on the TV are wrong. Sorry!

    Does your smart meter have a pulsing LED? If so, get a Geo Minim+ and monitor live consumption as you kill circuits on the consumer unit, in order to see where the consumption is going. If there is no flashing LED on the meter, you desperately need a working IHD.

    Getting back to dodgy maths, you appear to have gained a 500W load running 24/7 (like a security floodlight left on 24/7?), or it could be a 3kW load running 10 minutes an hour (immersion heater??).

    You'll only find it by doing some live monitoring.

    Ovo are sending me an IHD so when we get back from holiday, this is exactly what I'll be doing!

    I think I know why some people are confused. Its the way I was explaining it.

    The reason I compare year on year is because of the fallacy of comparing January consumption with say June consumption - one will almost certainly higher than the other.

    For June 2018-Aprilish 2019 the usage was typically the same as June 2018-April 2018

    In April/May our bill usually comes down about 50 quid a month - and it didn't this year which is why I looked into it.

    April-June our usage is consistently 400kW'ish more than April-June last year and is running almost the same as it was in January!

    The spreadsheet


    The grey values were pre-hottub

    The blue are two periods we were on holiday

    The red values are what I'm concerned about (June is a projection based on having used 490kW by the 15th)

    Still a little confused when you say "April -June" do you mean that in April and May and June ie every month your consumption in 400 kwh more than it was in the same months last year ?

    Yes - but the previous months were consistent with the previous year,

    no I cannot help, but you should monitor what is on! we saved 15% on our electric sue by installing LED lighting around our house.

    Why did your consumption decrease so much between September 2016 and September 2018 ?
