FCU at boiler

[telectrix]

its more what the boiler engineer thinks

boiler engineer thinks? contradiction in terms methinks.

Just hypothesising here - surely more points of isolation introduces more potential for confusion as stated, both by homeowners and other trades?

I could understand the need in commercial where there's multiple controls, multiple room stats etc. But in a typical British house, if the main isolator is just a few meters away and labelled, is there an issue? It certainly keeps it simple.


In my arrangement the 3a fused FCU operating the entire HWS/CH is in the airing cupboard. A label on the side of the boiler states: "Isolator in Airing Cupboard"

You can’t say that ??

That was my take on it to be honest, so long as it’s in a logical place and clearly labelled at both the programmer and boiler it seems safe.

I’ve looked at the gas safe regs and Can’t see anything saying the isolator needs to be within x feet of the boiler.

gas regs. also apparently say the gas must be bonded at the meter, even when the meter is outside and 20ft. of 10mm Gn/Y is run on the outside, from where the gas enters the building to the meter.

Gas regs day there must be a 10mm earth connected within 600mm of the meter and before the first T.

I’m currently going through the gas safe process and I’ve never seen a more obvious example of using training to tax people as this.

electric regs. say withing 600mm of where the gas pipe enters the building. no mention of the meter.

Thread isn’t about where to earth the pipe, it’s the isolate the boiler part.

my house, 13 years old had the heating isolator next to the programmer in the utility room.... the boiler was through the wall in the garage. At the time there was no adjoining door, so if boiler engineer turned everything off at this isolator, he had to trust we wouldn’t turn it back on. (Or take the fuse away or whatever)

One point of isolation is less confusing, even if that is the mcb in the board.... which can be locked off
