Isolator position for immersion heater?

[jstephens251]

Hi everyone,
just after some advice.
I've wired a new s plan system which has gone fine.
plumber has installed a pressurised tank in loft and I have wired the immersion to the customers off peak supply. The isolator for the immersion is in the Airing cupboard along with wiring centre and programmer.
They have had another electrician doing some work (I was working for plumber) and he has said I haven't followed regs regarding isolator for immersion? What's everyone's thoughts on this, I'm within 2M but it's in loft above, thought this would be easier for user to isolate.
many thanks
Jon

The main switch is the isolator. A single pole device should not be used for isolation in a domestic dwelling.

Quite right. Just to add, that any submerged heating element has to have double pole isolation switch within 3m of the fixed appliance.

By submerged Paul do you mean immersed? I think that immersed means the actual element is immersed, in a domestic immersion heater the element is enclosed.

Yes, under water lol. Thanks for correcting that

Not really a correction Paul as I'm unsure myself.
I'm sure there was a discussion here a year or so back which split opinion, I'm in the domestic immersion heater is not an immersed water heater camp.
