Howdy ​@AxIan !

 

The simple answer is that this particular meter has partial support for Economy 7. It can switch between the Peak and Off-Peak rate for the purposes of Billing and Meter Readings, but cannot physically switch the circuits on/off for you. For the parts the Meter can do, it can be reconfigured remotely.

 

The simplest solution if you need that would be to use your own timers on whatever you want to run only during Off-Peak, as that’d require the least wiring/re-wiring.

Yeah ok a lot here, The engineer should not have disconnected the e7 if it was still in use which leads me to believe the tenant has asked for it. 

If you want I can absolutely support an appointment being made so you can have E7 Load switching again?

I’ve got your account up ready. Cheers

 

You’ve got my account up? Oh. Did you get that from the serial number?

Yeah. it’s weird. I have no idea why the tenant would have requested that the storage heaters come on/charge all day at peak rate.

 

Having said that the cost per unit of the e7 ‘day’ is higher than a non-e7 rate. Could it actually be cheaper over the year to just pay the standard non-e7 rate 24/7 on the basis that heating is switched of most of year anyway?

Monies wise youve got to use approximately 2/3 of your daily energy usage overnight for the off peak tariff to be viable which is definitely easily achieved with the use of storage heaters…

But you are correct if you keep them off most of the year it would probably be cheaper to go onto a single rate bearing in mind the immersion usage aswell!!!!

Our engineers would not be able to make your off peak fuseboards 24/7 but we would fit a way that the electrician could connect it all up

    Customer Services say that we’d need a new, multi-rate meter in order to switch to a dual-rate tariff, but they’re no longer being produced?  New smart meters are being rolled out, and they’re single rate. Seems odd to me…  Would other suppliers have a different answer?

    Hi ​@jgmdavies, a warm welcome to the OVO Forum!

     

    Thanks for your post. Without having heard the conversation it’s hard to work out whether you’ve been mis-advised or not. To confirm, we are installing economy 7 smart meters, however at the moment we don’t have the capability to remotely switch a single rate smart meter to be dual rate. If you don’t mind, could I ask why it is you want economy 7? This will normally end up a more expensive option, unless you are using a lot of electricity at night. Generally, economy 7 is set up because a property has night time storage heaters - do you have storage heaters?

    Thanks Ben.  No, we don’t have storage heaters.  A plumber recommended a dual-rate tariff because of our immersion heater, but commented that we should do the maths - so I was trying to get a tariff quote just to do that.

    I can certainly see that Economy 7 may not be worth it if the peak-time charge is higher than with single-rate - we have no gas here, so the electricity cost is dominated by ‘awake time’ heating (electric boiler).

    Cheers,

    Jim
