Had a smart metre fitted today. Old THTC to E10. Fitting finished at 15.45, which showed Tariff rate .1894 on display and Storage heaters/water heater showed on and worked..This price is what I was told for the cheaper Tariff and heaters/water being on is what I would except for this time of day. At round 4.30pm tariff on display turned to .2402p which would be stitching to standard Tariff. Again this is what I would expect at this time of day. However the storage heaters turned off but the water heater stayed on. This is not the normal practice for off peak tariff under THTC.
As off 6pm the water heater ring is still live and should by now be off/no power. Storage heaters are off.
May understanding is the storage heaters and water heater on old THTC would remain the same on E10. Is this correct ?
This may well need just the metre to be reconfigured or the installation has not put a water heater circuit on the correct feed.
Does anyone have a direct number or which team I should be asking for to assist in this issue.
Cheers

Hey @Kirrimove
It might be best to contact the team to check if some simple remote commands would do the trick here.
It’s a common fix following 5 port installations where the 5th port isn’t working as it should, the commands from the team tend to fix things. We’ve got some other topics on this that may be helpful:
It’s tricky to tell if this will fix the issue but does sound like the most likely fix.
Do let us know how you get on.
… the storage heaters turned off but the water heater stayed on. This is not the normal practice for off peak tariff under THTC.
We’ve heard from another customer in a similar situation that on his THTC system, there were two feeds to the water heater: one on the offpeak circuit along with the storage heaters, and the other on the 24-hour cheap-rate heating circuit. This second feed would normally be off, governed by a switch by the hot water tank. It could be turned on to give a boost if all the hot water had been used up.
If your system was like this, then it sounds as if the boost switch is turned on. Of course, without the convenience of the 24-hour heating circuit, this boost will be at peak rate, for emergency use only!
The engineer should have made sure that all the equipment wired to the 24-hour heating circuit was now connected to the constant domestic supply along with every other appliance apart from the storage heaters. You could check the consumer units (fuse boxes) to see how the water heater is connected.
The other customer is in the Scottish Highlands. Where are you? Kirrie’s in the same region ...
