Sparkyheaven have it Softus, I had a quick read, not much change from what most people are doing really.
I thknk it's iffy to do away with bathroom bonding, and I wish they would have made an explicit statement about boiler bonding, because now that certain manufacturers instructions are including it we are in danger of a situation where we have to do something not in the regs because of MI's.
In my view boiler Central Heating MEBing refereed to in the Big brown book is only intended to apply when the heating introduces a potential from outside epz such as in a block of flats with shared heating, in the same way steel structure is main bonded because it is routed into the ground and introduces a potential from outside the epz. Other than that were the boiler in or proximal to the bathroom it could be used to perform bathroom bonding. Other than that there is no sensible reason to bond it any more than there is to bond a kitchen sink, and aslong as it isn't in zones 2 or 3 (cause you wouldn't find one in zone 1) it doesn't need bonding at all.
BUT I suspect they will be silent on this issue leaving heating engineers up and down the land bonding everything to everything, and more manufacturers sneaking it into their MI's aginst the intent of the regs..
It;s just one of the many things I have a bea in my bonnet about. So much that in my Napit inspection I asked him what he would do, and he said 4mm bonding as in a bathroom taken to cpc. OK so that is now my new minimum standard, but I think even that is over the top. Now if they actually do away with bathroom bonding altogether then aslong as it doesn't originate outside the epz boiler bonding should also be scrapped. It should only be bonded in the same way as a service pipe is bonded IF it originates outside the epzone.
I know OFF TOPIC.
