Radio telemeter series K

John Convery · Mar 4, 2023

I have a Horstmann Radio Telemeter series K that is not working. I have one consumer unit with all circuits. This consumer is fed via a normal standard tariff meter. I have a econ 7 timer for the hot water tank with two immersion heaters. Do I need to install a consumer unit for the hot water circuit and connect it to the radio telemeter.
Any help woul be gratefully accepted.
Many thanks

That's an unusual setup, I'd hazard a guess that someone has previously disconnected the live tail from the off-peak meter and fitted the Henley block to join it in to the 24hr meter.

Are you on an economy 7 tariff?

Strange incoming neutral arrangement as well. The neutral is series connected through both meters.
Only a link inside each meter, of course, so will work ok, but still odd.

can I take a live from the radio telemeter meter to a new consumer for the water heating which has econ 7 timer. At present the timer is wired into the whole house CU.

I have a econ 7 timer for the hot water cylinder with two immersion heaters with the times set from 12.30am to 7.30am. But this is connected into the general consumer.
I managed to speak to some one from SSE and was informed the the radio telemeter was switched off or disconnected in 2020 which was before I bought the house.
Any help would be very helpful.

Yes into another Cu then off to storage heaters etc , but you would be interfering with the meter, best to have a chat to your supplier.

Cant see the point if the Telemeter is switched off, though.

I would agree as the meter is sealed.
I am at a loss which is the best way to sort this.
It is becoming very expensive.

The seal is missing on the connection part.

If the RTS meter was switched off in 2020 then you can't currently be on an Economy & Tariff.
You need to speak to your supplier and request Economy 7, then either they will enable it on the meter again and the Immersion heaters will need connecting to it, or the supplier will come and fit a new meter that doesn't need RTS, see below.

In England the Radio signal that's used for switching Off peak meters (RTS) is going to be turned off in March 2024, it was originally to be March 2023.
I'm wondering if the radio signal is already off in your area, hence why the meter was disconnected and someone has moved the tails to standard tariff .

Or may be the same as me where I changed to a single tariff as I wasn't using enough on the Off peak to justify the increased Standard rate tariff.
The difference is though at the moment my RTS meter still works but I submit both readings which the supplier charges at the same Standard tarriff.

It hasn't stopped them emailing me regularly informing me I must change to a "Smart" meter before the RTS is turned off, otherwise my off peak may not work.

Thanks for all your help. I will speak to the supplier to find a way forward.

You as well, eh?

Note that if you revert to a dual tariff, you will be paying considerably more for the electricity used during 17 hours of the day than you do now. You will need to be using about a third of your electricity between midnight and 7am for this to be worthwhile.

Yes, couple of weeks ago,

They made the mistake of phoning last Thursday, after numerous emails. Wife answered, but passed her phone to me.
I'm not normally rude to call centre staff, just doing their job, but in this case I made an exception.

So, are you saying I should leave the installation as it is. Don’t reconnect the RTS meter.
Many thanks
