Nice one Andy I clean forgot about that one but spot on.

Where exactly does this information come from ?

I already quoted that (554.3.3) and GN1 (page 131) in post #3


Keep up at the back

Yes you did quote that and I missed that as well - well done pushrod. It was 1.00 in the morning (well that's my excuse)

Can't see how a timer is going to help you really. Even if you fit it and it comes on in line with your storage heaters, the circuit to the immersion heater is still going to be on connected to your normal tariff.


thanks for your help.isnt all my electric cheaper during e7 hours anyway?or just the storage heaters?

Under the 16th I was pulled by the NICEIC for coding a "plug top immersion domestic one" wanted to know whether it was different under the 17th so I need to look a bit closer into this one for the future.

Just looked a bit deeper into this, and domestic type immersion heaters are of an insulated type not an uninsulated type.

Therefore Regulation 554.3.3 does not apply to the type I'm referring too, the ones that are fitted into cylinders in domestic situations.

That's why the NICEIC put me in my place a about 4 years ago when I was carrying out PIR's under the 16th Edition and nothing as changed in the 17th Edition to my knowledge.

So a plug top is acceptable.

Cheers Tony

Hi im new to this site, you are correct the Imm Heater should not be on a plug top nor should it be on a 13 amp double pole fused spur, it should be on a 20 amp doulbe pole unfused spure, the reason being is that under current regs the 13 amp double pole fused spure falls below the required protection, this is due to the current regs using the voltage range of 230V and not 240V calc this and you will come up with 2990 watts, and as you have stated the IMM heater is 3KW no diversity allowed 100%, and as for the shower pump is the plug top located out side the zones, if so then this would be ok acording to current regs, under a bath with a fixed panel screwd would also meet current regs, as this is clased as having to use a tool to gain access to under the bath, but must be fused acording to raiting of pump.
If not no cert can be issued for work, pump does not require one if out side zone on plug top. but IMM heater will.

Ps as for the IMM heater being on circuit with pump, sorry but this is a ano can do, IMM heater as Markie says if over 15liter should be on dedicated circuit.
