Not true, scale filter isn't required on an unvented
Now if it is over 200ppm then you require a softening

Apart from the bits and bobs others have mentioned it looks good.
The only wee thing I would add is that the immersion would be best on a 20 Amp Switch as opposed to a 13 Amp switched fused spur.
Cheers last!! An electrician wired up the immersion lol immersion’s don’t draw more than 13 amps, why would you need a 20 amp switch?
I actually had the same point about immersion switches on this forum and it was clarified by some of the more electrical experienced guys, maybe Shaun.
The immersion works on the limit of 13amp, so a spur switch that is 13amp might burn out at the internal switches (for neutral and live) or at the 13 amp fuse.
It depends on if the supply is 240 volt or if it is lower, because the amps raise if voltage lowers I think.
Normally you will have 15 or 16 amp fuse or the mcb fuses at electric consumer unit and then any switches on that for the immersion should be 20 amp 2 pole switches.
Makes sense.. thanks for clarifying Best 🙂
Correct best but in certain circumstances the immersion can be taken off the ring main and doesn't need its own circuit
I went to service a megaflo about a month ago and had Main and boost immersion wired together using a single cable into a 16amp circuit breaker.. disconnected the boost immediately!!!
It's weird as a stnd immersion can pull around 12-13 amps
but to trip a fuse you would need to be pulling around 26 amps and on a mcb closer to 20 amps scary lol
Both 3kw immersion or a 1.5kw and 3kw ?
Most can't even wire an s plan it's getting less and less that are able to do it
On the subject of 13amp spur switch on immersion’s being totally wrong, - my house had same in airing cupboard as the final isolator for immersion. Had been working perfectly for over 40 years of daily use, until I replaced it with a 20 amp switch with neon.
But the old MK switch was probably better quality than the new switches

And do you realise standard 13amp fcu will be rated at around 18amps for safety (able to take 13amps easy)
2 x 3kw elements
Lol I were’nt gonna Flick the switch 😉
Funnily enough the cylinder was heated by the boiler so I didn’t need to test them both.. just disconnected the boost and tested the main.
Probably shouldn’t say this but I do my own wiring.
So do I easier in the long run
Same here..
Yes, a friend of mine is an electrical/electronics guy and told me the fuses are rated much higher.
Not sure what extra % of amps he told me, but think he said they could take surges for short periods.
I am still trying to learn the more technical bits of electrics.
About 11/2 times rated amps for an hour
Twas I, many moons ago !
