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 

Adam

    25,000 kwh is an average load of about 3kw, or after allowing for a normal domestic usage perhaps an EXTRA load of about 2.0 to 2.5 kw.

    Likely culprits are in my experience, an electric water heater left on, or with the hot water leaking to waste.

    An anti frost heater with a defective or wrongly set thermostat. Any sheds or greenhouses or garage with an electricity supply.

    Any close neighbours who might be using your supply, either due to deliberate dishonesty or a simple misunderstanding.
