Was called to a job by a reasonably local plumber this morning who was re instating a new 3kW immersion heater in a house. Since the immersion was ripped out 10 years ago the house has been rewired and no circuit remains for the immersion as there was not one in at the time of the rewire. Never worked for the plumber before, he said he always does this himself and taps off the ring main via a 13A FCU, but he needed a NIC cert for this one. So of course i ignore him and start ripping up some boards to get a route back to the mains, about 8-10 metre run. Starts having a pop at me saying im wasting my time and doing more work than necessary to over charge the client. A quick flick through the OSG
and choice words to him i left him to it and told him to find some mug to do it.

Trades on its arse.
 
If he knows best mate let him do it,I wouldn’t even explain the regs to someone like that!
 
3kw devided by 230v.... his 13A fuse isn’t going to last long.
16A MCB to dp switch. Like it’s always been.

The plumber is just going to trawl through cowboys-r-us until he finds someone to issue him a cert
 
I had one this week 2x3kw on a 15amp 3036 fuse .wet pant more like wet a88S .I now call them peter the pipe fitter , cause peter was the boy who shoved is finger in damm.stopping all the water from coming out.
 
Is this immersion heater a backup element in a cylinder heated by a boiler or a primary source of hot water?
If it is a backup element then for the very occasional use it gets I would be happy supplying it from a ring circuit.
 
It was a 150L Immersion, used as the primary hot water source.

Eh? Do you mean a 150L tank which is the primary source of hot water or that the immersion heater is the primary means of heating the 150L tank?

If the immersion is the primary means of heating the tank then what have they been doing for hot water for the last ten years?
