Hi there,
I built a house with ground source heating 5 years ago and it's a fairly large house so I have 3 phase supply 80 amps per phase. I had a regular meter it was a Elster A1140. I read this every month on the 1st and logged the readings so I have a good idea of my usage patterns. Ground source is pretty power hungry in the colder months.
As I have an EV I decided to move to a smart meter to be able to use a cheaper overnight tariff. The new meter is a EDMI ES-30B. It was installed on the 1st of November this year and the readings are much higher than my old meter.
For example in November 2022 I used 1942kwh. According to the new meter in November 2023 I used 9731kwh – nothing has changed at home in this period and the reading in October 23 was normal.
I have sent this info to EON my supplier and they are “looking at it” but I wondered if anyone could come up with what they the issue could be, could the person installing the meter someone installed the cables incorrectly or could it just be a faulty meter.
I have ordered a 3 phase clamp meter to try and verify the readings.
Many thanks,
Jonathan
