Is economy 7 on a separate feed/line?

[philv]

I have economy 7 eon.

I used to have economy 10.

With economy 10 there is a second feed from the meter that only supplies electricity during the cheap 10 hours.
The other feed is always live and is for everything non storage heater.


Does economy 7 run on a second feed?
Or is the entire property on economy 7 and its just those 7 hours are cheaper?

Im trying to work out if the storage heater needs a timer to tell it when to charge the bricks inside.

If the circuit it is on is always live i will need a timer.
With economy 10 i didn't need a timer as it was only live for 10 hours.

Thanks

The economy 7 should have a separate circuit which goes live during the E7 hours. My house is set up for E7 with the immersion heater on that circuit. I'm not actually on an Economy 7 tariff anymore but on IOG but the E7 still switches on the circuit for the E7 times.

Not necessarily. It can be configured as you say, but I have economy 7 with a dual rate meter. There is a single supply and the meter has two dials and an indicator of which shows whether the low or normal mode is active. I think the separate circuit is only useful if you have storage heaters.

We had E7 (actually had 8hrs as the clock had been set wrong) and whole house benefitted - the meter was dual rate and it just switched from day to night when the time-clock told it to. Actuallly it used to stick on night rate about once a week, which could be quite handy.

Sadly when our house was refurbed and the consumer unit replaced the electrician took it out as he didn't think anyone used E7 any more.

Thanks for the replies.

So it depends!

I suppose i can try charging the storage heater during the day.
If it charges then not on a separate feed.

From what I understand, economy 10 gives a midday boost for an hour or so, but not sure if it is cheaper during than time and for those circuits there is a separate fuse box.

Economy 7 is just between set hours at night.

The whole house does not benefit fronE7 hours as far as I’m aware.

My electric meter is a dual one

There is a little arrow which shows if the E7 (night) meter is being used or the non E7 (Day) meter is being used

As far as I understand it the entire house switches to low rate but the E7 circuit is only live when low rate is active. The meter is not capable of metering two circuits, it is low rate or high rate. To meter separately would require two meters surely.
