Smart meter installed as Economy 10 - how will this affect my cylinder water supply?

Smart meter installed/replaced today, will update if any issues. Engineer was a lovely chap, gone for economy 10 as split over 3 sections in 24 hours. Just minding on we have a 210 litre unvented cylinder which was wired to heat in the offpeak previously, this should remain the same ie heat during those new off peak timeslots? Also the old economy 7 boost box was left in situ and advised to continue using this for a boost if required (but hopeful the boosts will be less necessary if heating up the water during 3 slots during the day). There is no boost function on the new meter. See pic of meter and said boost box/new meter set up.

Hi ​@Albot81!

 

Thanks for creating this helpful topic. I’m really happy to hear that the appointment went well, and thank you for the kind feedback about our engineer. If you remember their name we’ll be able to pass the feedback on to their manager. Fingers crossed - Economy 10 should ensure that the water is heated up regularly enough so that the old Boost function isn’t required. I just want to link in ​@Blastoise186 here as well as can see he was speaking to you previously about this.

 

Keep us updated as to how it goes with your new set up. I’ve linked some handy previous topics below 👇

 

 

That's great, OVO got back on the chat today just to say it'll take 6 weeks for it all to synch, and then the boost option should appear on the IHD, and also link up with the new regime. Hours were still to be confirmed they said due to synching.

Good old Latif and his mothership connections! He's been back to reset after speaking to his work/hub, to reset a few things at their end and recheck. Like say know its early days and will see is heating the cylinder efficiently, the IHD shows red which i know means everything on (during corrected off peak hours) as is heating the immersion and the storage heaters (plus usual appliances etc). I'm going to refresh myself with all things Quantum HHR dimplex heaters and how they function again!

Both taken at 20.44 at off peak charging.

Thanks all and ​@Firedog yes I'll be patient, as checking account on the app now ots updated the plan to economy 10, but suddenly says we're 900 pounds in debit, from being in credit just prior to installation on the 17th! So hopefully that will all work itself out. I know we're high usage but always sent monthly updated readings etc and kept on top of that side of things.

@Abby_OVO i have submitted a complaint today regarding some bizarre and dubious readings that were documented in the days prior to the smart meter being installed, this is after 3 days of being told it's been rectified and showing on the acct. 900 pounds worth of energy in 6 days? Latif the most helpful of guys before he went back down to Wales tomorrow, rang me today to check, and was baffled about this, as the readings sent by him (and my actual ones in days prior) were not logged despite being rung through, and some hugely inflated numbers were documented the day before his arrival instead. I was reassured by the call centre yesterday that the correct readings were now on board, and it did seem a bit unbelievable to them too. Correct readings confirmed by Latif, but still day 3, after 'billing investigation' that we owe 900 quid. Bonkers.

Also i included that i have had no discussion with support, despite asking, that we were using 6 days on the wrong tariff, peak times etc.

I can only repeat what I wrote earlier: please be patient! It can take weeks for everything to settle down, including billing.

You say “we owe 900 quid”. Have you had a bill for this amount? Or are you looking at figures in your online account that will still be in a state of flux as the many changes that have to take place filter through the systems? 

Once everything is in place, you can start making sure that the closing readings for the old meters and the opening ones for the new one are the ones Latif noted down and reported. He should also have left a Meter Exchange Label by the meter with those details on it. For peace of mind, make sure you have a photo of it salted away somewhere safe. I wish I had - mice ate mine.

Once the exchange readings have been applied to a bill, you can start calculating how much extra you will have been billed because your heaters were charging at peak rates some of the time.

Thanks ​@Firedog he did indeed write a label and have kept away from rodents so far! I will, i know it's just away from Latif and you guys, i haven't found the support services very good at communicating or listening to concerns really. It just shows on the account on thr app, yes as a Bill was generated for Jan into Feb 13 which amends to differing numbers prior to the smart meter, although they were correctly inputted as actual on the 10th/13th Feb. Again then going to the 19th Feb, this was before the smart meter installation the day after, and numbers that were way above the ones Latif sent through the day after. Hence my confusion, it isn't so much after install, as is before it. This is all under bill pending. But the actual bill shows we used 900 pounds worth in 9 days 10-19 Feb based on amended after the time estimated readings even though it had recorded my actual, all just looks a bit crackers. Anyway, appreciate it as ever I'll keep an eye out over the next few weeks. Apologies for if seems a vent and thanks again.

I had a smart meter put in a month ago but only now in the property. The water in the morning is only luke-warm as if it has not been heated up at all in the morning. I am on Economy 10. Could something be out of sync with my water heater and the off-peak timings do you think?

Thanks you.
