Really high night time usage - eco 7

SouthamptonExPat

Hi everyone. This might be a standard question, however I’d appreciate any suggestions you can offer as to why my night time usage might be high!

My evening energy usage seems to be ridiculously high (2,200 kWh for 4 months). I only have electric in my flat and have an eco 7 water heater and eco 7 storage heaters, which are the only things that would be using energy at night. For comparison on daytime usage is 630 for the same period. My flat is a one bed.

Looks to be about average. On target for about 4000 night units and 2000 day units - at about 9p for night and 19p for day is less than £500 in the year.



Actual or Estimated consumption ?

Heating and hot water uses the greatest part of this, and when on eco 7 this will appear as your night units.


Your average over 4 months is about 18 kWh per day. That is 2.6 kW over the 7 hours of the eco tariff. You probably have at least 5 kW of appliances connected so this is reasonable.


Still take weekly or monthly readings and you should see the consumption decline into Spring then Summer.

Thanks for the replies. This is based on actual usage numbers.

A storage heater will consume, depending on size, between 6 and 24 kWh per night and an E7 tank around 6 - 10 kWh, again depending on size, so you can see how it adds up.
