Immersion heater/timer

CasualMFW

Thank you for all of the replies so far, I have attached some photos of my current set up for those asking. It's a range tribune ti150pt4eup pre plumbed cylinder twin zone. The twin zone, I presume is due to upstairs and downstairs being on different circuits.

Please excuse the dust accumulating in the airing cupboard!

What sort of meter do you have? How will 'Pus know that you used this leccy overnight? That's the first thing to find out - if necessary, ask them. Or post a pic of your meter and see if anyone on here understands it.

And then there's the controlling/timing of the immersion. For this, it would help to see what switches you currently have in the 'airing' cupboard that supply it.

I'm already on the go rate, 🐙 take readings every half hour, can't see why or how they wouldn't know this additional usage was overnight?

I have attached some photos to my previous post of the switches.

If you look at your third pic, Cas, you'll see motorised valves labelled upstairs and down. These will be for the central heating radiators, hence the 'twin zone'.

To the right is these two is a third m-v. That's the one that opens to heat up your hot tank from the boiler.

In your second pic is the electric heating for the tank - ie the immersion heater switch. Your timer, to turn it on for the cheap rate, will be wired in there. Two basic options - the usual programmable timer as mentioned above by others, or the T-smart (or whatever it's called) which slips in to the immersion element and gives App control. Both are cheapish and simple to install. Which to go for is your personal choice.

Cool - it would seem that Octo will monitor power use, and when, so that's all good.

Thank you for your detailed response, much appreciated.
