I had a plumber years ago in to fix a leak at the HW cylinder and he ended up replacing the whole thing.
The immersion element was moved to the new cylinder but never wired back in.
I would like get the immersion wired again and on a smart switch which I thought should be a simple DIY job but taking a look at the electrical wiring I can see why the plumber didn't want to touch it...
One 3-core bring power down into a fused switch which then enters this junction box from the rear
Two 3-core cables exit the bottom to the junction box and go up to the boiler upstairs (at least one of them does dunno what the other is)
Black cable (grey and orange cores?) goes to the motorized valve which doesn't seem to work)
White cable exits bottom left and goes to the thermostat on the cylinder
Something exits the hole in the back and goes the heating controller/timer mounted above.
So my question(s) is is this the "normal" way to hook all of this up? How would this be done properly? or is it perfectly fine?
should I just get some heat resistant 3-core and "jack" into an earth, live and neutral in this box and take it to immersion element via a smart switch?
