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

    The original post says there has been am issue since the installation was changed to three phase. 

    To state the obvious,  it hasn't been changed to three phase,  it's two phase supplied through a three phase meter, so there's no balance across the phases at all.

    Why do you feel this makes any difference? 

    The meter doesn't care whether the phases are balanced or not... it simply measures & accumulates the total energy passing through. It will do this correctly whether the load is balanced, unbalanced, single phase, two phase or three phase.

    I may need new spectacles, but where does it say that?

    I just replied with a quote of the relevant comment, now I cannot find it on this mess of a forum, it really is hopeless.

    agree, hopeless, the  idea that 'newest' and 'oldest' sorting options might actually be supposed to sort posts in time order, and nothing else, not who it was written by, by who it was a reply to, or from or someone's idea of favourite , seems to be utterly lost on the programmers. There was talk of changing the meaning of the reply buttons to make it clearer that there were multiple flavours, but that has not happened yet  either.

    The forum has changed, you just have not noticed, the reply button to this comment now says “Reply to Sparkingchip” rather than just “”Reply” to differentiate it from the Reply button at the top of the page that adds onto to end of the whole thread.
