On peak off peak wired incorrectly?

[snowhead]

As L-S above, there isn't a supply labelled for the Off Peak Immersion and there would normally be a controller with time clock set to switch on the lower Off peak imersion on during the off peak hours for 2 or 3 hrs.
As noted above Off Peak is probably 7 hrs overnight and 3 during the day.

Re the water temperature and the thermostats, the lower due to it's location should be around 45c and upper (middle of cylinder) should only be around 50c max, to get 60c at the top.
If the water is still too hot when you have them set at 30c then the thermostats need replacing.

What's the betting the other element is feed from the ring.

Ok.. so if the shower is giving problems with too much or too little heat, then its a problem with the shower itself.
It may be that its too big for the supply RCBO.... but you cant upgrade that unless the cable is big enough.
(9500 / 230v = 41A.... bigger than 32..... )

I couldn't tell by the photo which immersion is connected to which switch.

An electrician should be able to tell which is which, even with a non-contact detector would give a good indication.

Someone may correct me on the following.....

The E10 tariff would mean 7 hours off peak overnight, and another 3 during the day.

Depending how its all set up.... The older systems gave you cheap rate on all your electric overnight.... Newer ones, just the heating.
So the Hall Heater on the 3rd circuit could be on high rate all the time.

There is only 2 storage heaters on the Off peak, so where is the second immersion supplied from?

The shower I’m not too fussed over re cost as it’s not on long enough to lose sleep over although my only concern is that the water is so hot due to the tank being boiled ‘like a kettle’ all day due to the switches being incorrect and the on peak kicking in all day?

I’ve had 4 electricians here and not many are able to tell me the problem, I did have one but he quoted me £10,000 to do a full replacement

For info - I have 3 500W electric dimplex heaters in hallway, room 1 and room 2
1 x XLE 1.5KW dimplex storage heater in living room / kitchen (open plan)

Thank you for your reply - I am Not sure what this means but assuming you are talking to the other professionals

Where exactly is the water too hot, sink or shower?

also, where is the thermostat that you are adjusting to change the water temperature?

Both

Found the key for the meter

Some pictures of the current aet up would help

Without taking any covers off consumer units etc can you photograph your consumer unit and meter set up and post it online?

Several would be good
Close up and from a distance

yes, but I have found were some emersion heater are feed from the socket circuit .

Hi MeganS
In relation to the two switches "off-peak" and "on-peak" connected with white wires to the immersion heaters, could you follow the cable from the bottom switch and check if it goes to the bottom or top immersion, and similarly the other cable from the top switch goes to which immersion?
I am puzzled by the fact that the light is lit on the bottom switch - did you take the photo during the day, or at night (or to be more accurate, during 'off-peak)?
It would be good to know if the switches are labelled the right way round, and the above might confirm!

PS photo's of your meter etc helpful thank you!
