Hello, I have two meters, one for standard electricity and the other which connected to a radio signal meter. I have two consumer units, one for standard electricity and the other for storage heating which I do not have. The consumer unit which is connected to the radio meter has a large sticker on it which says PERMANENTLY CONNECTED. This supply although from the radio meter never goes off. I have underfloor heating and hot water which runs from this consumer unit and is on all the time apart from when the room thermostats switch it off. Would I need to smart meters. Is this setup correct. Thank you all.

Hey ​@Confused358 ,

Based on what you’re saying… I think you’ve got a THTC (Total Heat Total Control) setup - with this type, certain heating sources are allowed to run 24/7/365 at a reduced rate. This is not a recommended option if you no longer have Storage Heaters and Immersion Heaters - it’s probably costing you more than it should.

You will need to swap for a Smart Meter to resolve this. Support for ALL RTS Meters are being phased out over the next couple of years and the shutdown process has already started - some areas of the country have already had RTS Services disabled for example.

I’d suggest having a word with OVO about this and see what other tariff options might be more suitable for you. But before you do that, can you post some photos of the meter setup real quick? If you can, I might be able to give more accurate advice.

Thanks!

Hello Blastoise186, Thank you for the information. I will try and put some photos on when I get out of hospital. I am 87 and not very good with the modern technology but I will give it a try, Thank you once again.

Sorry for being a bit slow to get back to you - I had to catch up on a few other things which needed my attention.

Please, by all means feel free to focus on your recovery first - your health is more important and I’m OK with waiting until you’re back home before picking this back up again. If you do struggle to get the photos up, please don’t panic as they’re not crucial. I think I’ve got a pretty good idea of how the setup works even without them - the photos would have just made it a little easier to be sure.

Based on what you’ve said though, I’m definitely pretty confident you do have an RTS (Radio Teleswitch) Meter of some kind so I’ll do some digging through my notes I have on them and see if I can get a lock on the exact type based on what you’ve shared.

If you feel comfortable replying to this thread, please feel free to do so at your convenience. I’ll be here when you feel ready to talk again.

I hope you get well soon.

It seems like you have an old off-peak / radio teleswitch setup originally installed to operate storage heating. If the underfloor heating and hot water are working correctly, the system may not be an issue, although I would advise you to check with your supplier if the tariff is still active and would need in terms of 1 or 2 smart meters.

Hey ​@Confused358

 

I just wanted to let you know that I checked our email inbox and noticed you replied to the email instead of the post. No worries! I’ve gone ahead and moved it over to your thread, and I've included the screenshots for you below.

 

“Hello Everybody, Thank you for the kind words, I am now home and ok. I have put on pictures of my bill and the new one for when my two meters will be removed and a smart meter put in on the 18th of this month. Please send any comments if I have managed to do this. I am not good with technology so if the pictures are not there I will write them out and post them. Thank you all once again.”
