Right, I’ve found out some more about this boiler. It’s a valliant ecotec plus 837 installed 28/02/2011. It’s in an integral garage on an external wall. About 750mm away from the internal door to the kitchen and the other side of that door is an external door from the kitchen to the outside wall on which the boiler is mounted.
So, which regs have changed in the last 4 years that relate to the comment “gas/elec/con pipe”.
Mentioned above is the move to a larger diameter con pipe, so that might be that one but when did it change?
Has the spec for the electrical connect changed though? It’s been an isolatable fused spur and earth bonding for more than 4 years hasn’t it?
As for gas, that’s a bit of a vague comment I’d imagine. It’s that what a lot of the regs would be about?
By those dates, it was installed to 6tg edition, second amendment and the most recent service was to 7th edition if Google is right.
