… underfloor heating was on Heatrae Sadia electric boiler, installed when house was built in 2008, by builder and heating engineers. They set up Economy 10 meter for this. 
 

It could well be that Economy 10 was a good choice for an electric-boiler-driven underfloor heating system in 2008, but I’m not sure it’s the best option for a heat-pump-driven system in 2025. There are a few years until your meter reaches its best-before date (September 2031), but you might consider accepting the offer of a smart meter now so you have better control over your energy use and a choice of tariffs.

Hi ​@JohnH68 and a warm welcome to the OVO Forum! I’ve added your Heat Pump badge 😁.

 

I can see ​@Firedog has given some really helpful advice here, and I’m in agreement that a smart meter would be a great idea. You can find some more info on smart meters in these previous Forum topics:

I am in a PH postcode and my appointment was cancelled due to operational reasons with little explanation.

 

It turns out it’s a signal issue and they have no idea when it will be fixed or if it will be fixed in time for the shutdown. I only was told this because I phoned back despite being told I’d be able to get the next available appointment when my appointment was cancelled and they would phone me.  

 

furthermore I haven’t been able to speak to someone that knows when this issue will be resolved I’ve just been put on a callback list. I’m getting a little worried now that I might be trapped.

Hey ​@Jkraw1 

 

Sorry to hear about this, sadly you’re not alone in this and there are a few others on the Forum who are awaiting a fix for similar issues.

 

The team will be in touch as soon as they have further development on what’s going to work for yourself, the solutions may be different for some people so they will be in touch directly.

 

I’ve linked below to a couple of similar topics which may also be helpful:

 

 

I’m sorry it’s not quite the answer you’re looking for, but hopefully the team will have a solution for you ASAP.

 

Do keep us updated on how you get on.

Had appointment booked to install smart meter on 22nd April. All last week I kept getting emails and text messages reminfing me about it and what would happen. This morning (the 21st) I’ve received an email saying appointment has been cancelled. No explanation, No reason given. This doesn't bode well for getting them all done by the switch off.

Friends have just bought a flat with storage heaters and immersion for hot water, this is their meter. Is there anything peculiar about it that they need to be aware of before booking a smart meter ? The meter cupboard is outside their front door on the second floor stairwell. They are in KT5 and with Octopus.

Booked new appointment for 20th May hopefully this one goes ahead. If not will definitely be cutting it fine for RTS switch off.

The link below seems to indicate that a Economy 10 type meter needs to be replaced. This is contrary to advice given above.

@Firedog anything odd here ⬆️?

That article is only about RTS-controlled systems, which yours apparently isn’t. Your meter doesn’t have to be replaced until 2031, but it might be a good idea to have it exchanged for a smart meter before then, to give you better oversight of your electricity usage.

Hi Julia

Nothing that a feather duster and a baby hoover wouldn’t fix! 

To my inexpert eye, that looks like quite a straightforward job for a competent meter engineer. Everything in one place, and plenty of room for the new meter. Assuming the storage heaters and the immersion heater are all on a switched circuit for charging, I can’t see any reason to suspect that a smart meter exchange couldn’t be completed in an hour or two.

Thanks, that’s great news !! I’ll take a duster next time I’m there… 🥲

No damp cloths, mind. They don’t play nicely with old live electrical cables⚡

Just worth mentioning ​@juliamc that there is a split feed from the main fuse 

(2 live cables and 2 neutrals).

It shouldn’t be too much of a problem but the engineer might need to remove one of the feeds as the smart meter will only take one of each

Oo.. does that mean further works in the flat’s electrics ? Any thoughts where the two feeds might go ?

They have an electric oven and electric shower as well as the immersion and 4 storage heaters. There’s a gas supply for the hob (the only gas appliance).

You can see that one feed goes to the normal meter and the other goes to the teleswitch. That’s probably to do with the different circuits being energised at different time slots.

With the new smart meter (presumably on E10?), it will provide the switch for peak and off-peak although I can’t see the various circuits so don’t know how they’re currently connected.

😁 well looking further, the outputs from each of the meters goes into a tube at the base of the cupboard so I presume these then feed into the consumer unit /DB

That main fuse is rated 415V 60/80A. Might that suggest that there is in fact a three-phase supply, with one of two feeding only the heavy duty stuff via the RTS?

There’s only one fuse which means it’s single phase

I did wonder why the fuse has 2 numbers on it.

It’s definitely single phase - Henley make the same style unit today. The markings are generic as the moulding can take either rated fuse and there is a three phase version but that does have three fuses

Hi guys 

 

I’m looking to get an appointment for the removal of my THTC, but your customer service said I’m not having a THTC when I even send pictures of my meter reader… so I think it’s just a machine replaying my emails. I live in Argyll & Bute. 
Thanks
