UK synchronisation of storage heaters and Economy 7 supply timings.

[keithrawes]

please could somebody tell me how storage heaters are linked/synchronised with the electricity supplier so that they switch themselves off and on to coincide with the timings of the Economy 7 rate. In my case, for example, the E7 timings are allegedly 11.30 to 6.30am but the storage heaters are still taking in current up to 8.30 am. Is this 'extra' two hours being charged for at the day or night rate and how do i find out. All enquiries to SSE and Dimplex have got nowhere. Thanks.

Storage heaters are normally switched by the supply authority timeswitch, which will change the tariff over at the same time. If your heaters are still live at 8.30 it is possible the timeswitch is out, but nevertheless the tariff will still switch over with the heaters, so it doesnt make any difference.
A pic of the meter setup would clarify.

Sounds like the timing is out of synch, but that can work to your advantage, because the whole installation will be on off peak too, as advised a pic of the set up please.

As above, it sounds like the time switch is at the wrong time, they have battery's to keep them working during power cuts but batteries can fail. Time switches should be set to GMT. You should be able to check the time setting by looking at the front of the time switch, post a close up pic if you are having difficulty reading it.

To the OP, are you talking about modern 'smart' storage heaters - like the Dimplex Quantum for example ?
If so I'm sure you can adjust the settings on the control panel to match the E7 times.

 

[keithrawes]

many, many thanks everybody - i'll try and take a pic of the meter and post it - problem is i'm in a block of flats and all the meters are in a cupboard somewhere in the basement that the housekeeper has the key to.. The storage heaters themselves are a pretty old - Dimplex NC3300Combi and NC1700. About 30 years old i would guess. Watch this space.

 

[Dave OCD]

In that case your heaters will only be getting power via cheap rate electricity - regardless of the meter timings. I assume you have two consumer units ?

 

[Mark42]

If you really do have, as others have suggested an antique timeswitch installation which is set to an incorrect time, then rejoice in the fact that you are getting cheap-rate electricity at peak-rate morning times. Keeping schtum might be the best option ?. Although of course you miss out on the late evening cheap rate, so any benefit depends on your personal routine.

It's years since I messed with storage heaters. I did think that all the timers were changed to 'radioteleswitches' years ago, which use a radio time sigal for switching.

The worst scenario is that you have an independent timeswitch somewhere for the storage heater circuits, which, as you suspect, is out of sync with the supply timer. Storage heaters are horrible at the best of times, but charging them with peak rate electricity compounds the offence!

failed on the photo mission as the housekeeper's away and the meter cupboard's locked but i think i have learned what i needed to know from your replies. If the supply and the storage heaters are always synchronised to go on and off together whatever the time then i know what to do and when to do it so as to take advantage of how it is currently set up. SSE want me to change to a smart meter but my understanding is this will be installed in the down stairs meter cupboard three floors and fifty yards away and thus too distant for a wifi read-out in the flat. So i don't know if there's anything in it for me and i might lose the advantages that currently come from changes in the accidental time switching from 6.30 to 8.30 am. Yes?

The decision really is in your court, you are quite correct the smart meter will be installed in the meter room downstairs, I am 99% that with that distance the ppmid (home display unit) will be out of range, so the only advantage to you and the energy supplier will be remote real time meter readings.

 

[keithrawes]

sorry dave what are 'remote real time meter readings' - a way of checking usage on the web?

The smart meter would send readings to your energy supplier, so no need to read it manually thus no estimated billing.

so the only advantage to the energy supplier will be remote real time meter readings.

Plus the smart meter has an internal contactor, giving the supplier the option of cutting off your electricity with a few taps on a keyboard.

thanks dave

thanks for the warning brian - so while the smart meter effectively puts the supply usage on the internet if the customer is without a relay system (like me) only the supplier has direct access to the data. I have to contact the supplier (and we all know how long that takes!) to find out the figures for night and day usage. Yes?
