Since switching to three phase my consumption has rocketed to 25,000KWH per annum, despite no significant additional load.

adam spearing

We moved to three phase 3.5 years ago an anticipation of electric cars (which we don't have). 

Since then We have been consuming around 25,000KWH pa according to the meter. 

I've had a second meter fitted and it's validated these numbers. 

When I switch all the RCDs off it stops, so clearly it's my side of the RCDs. 

The house is around 10 years old with gas heating and gas cooking. We have low energy light bulbs. 

The overnight consumption seems to show we're using 4+KWH per hour when we're asleep. 

Load balancing was mentioned and I vaguely remember it from my degree but I don't believe that's it. 

Large donation to charity if you can help me work this one out

thanks in advance

    Ahah - is the aga the sort that stays hot all the time, and same question the hot tub - basically anything that  is heating the outside world that is not the gas  boiler is a good suspect.

    estimates of some AGA consumption - based on last years electricity prices

    An article that suggests that a good hot tub needs at least a 4 inch thick insulated tight fitting cover, and even thicker insulation all round the sides. I like the idea of the snow should not melt test.

    And did any your use of either  the aga or the hot tub change at about the time you got the 3 phase supply ?

    An electric AGA is a disaster waiting to happen. The fuel is just too expensive however "nice to have" signalling it is! Oil or gas used to be OK but now....And a hot tub in winter? Or even a greenhouse heater, these are for the super rich only.

    The old meter was installed in 2011 (when we built the house) so it wasn't that old. I've never kept my old elec statements and since NPower was absorbed into EoN I can't get an old statement from them. However the bill was only around £100 PCM before this Phase meter.

    I have had to rewire a few electric storage Aga cookers, because people could not read the instructions and did not understand off-peak supplies.

    One installation had both sets of tails commoned in a Henly block and then separated again, to supply the separate consumer units.

    "Saving" one phase for an EV charger is actually ridiculous, as you can have a three phase charger which will be far more efficient.

    You need to address the lack of balancing across the phases.

    It would be good if it had an off peak supply. but it rather sounds like it doesn't. Can they be programmed to turn the ovens off at night, and come on again in time for breakfast. ?
    It is after all what you'd do with central heating. The idea of an 'always on' heater to mimic an always lit fireplace sounds like an odd solution.

    The Aga, is it a proper electric storage Age or are you just referring to a big cooker?

    If it is an Electric storage Aga then that would definitely be the prime suspect.

    Alas no, It's a gas aga.... with a power flue

    You can discount the Aga as it is gas fired.

    Why? (I'm referring to needing to address the lack of phase balancing)
