Immersion Heater Circuit

[NewbieRuffy]

I have a plumber mate who is installing an (3Kw I believe) Immersion heater into a property and needs it wired in. I know in an ideal world, i new circuit from the CU, 16A CB and 20A FCU, as we all know the world is not always ideal and getting a new circuit from the CU to the airing cupboard upstairs is not at all going to be easy as the customer doesn't want walls chased out floors taken up and so on. So, as I am still gaining experience and this is my first immersion connection can i spur off the RFC on upstairs sockets? I have checked the Reg's and cant find anything that says i cant, however anything over 2KW usually needs its own circuit though right? there isn't much load on the upstairs RFC, couple of TV's, laptop now and again, general stuff. Your thoughts please?

Well, ...he does live in a light bulb, bless him!! lol!!!

big lol!!! not

... yet your solution here is to effectively downgrade the circuit by 12A.

not quite.
splitting a 32amp ring into 2 x 20amp radials gives you a net gain of 8amps extra capacity.

my reasoning of splitting the ring was seperation of circuits if the op wants to feed the immersion

Yes Sedgy, and I owe you an apology as I realised long after that post that what you meant was 2 x radials, and not how I had read it. I still think it's a lot of fuss over nothing, btw, and branches/spurs from standard domestic ring finals to feed immersion tanks will outlive both of us.

Look, I post an apology - which let's face it tend to be few and far between on here, and it wasn't exactly a massive insult to start with - and all you want to do is get pithy over it?

Not at all it's too easy to take the p**s

appendix 8 I belive on site guide ( if not current 2004 )Water storge heaters in excess of of ( i think 15 /17 litres ) or perm connected to be fed via seperate circuit ( or words to that effect ) simples - all rush for the on site guide!!!

Now does anybody want to discuss flower pots and if that dosent raise a smile you havent been on here long enough!
