Hi Guys,
Have just had a local plumber round to give us a quote on fitting a new boiler we have already purchased (Vaillant Ecotec 618 System)
The feed from the meter is 15mm throughout to the existing gas hob and boiler. The connection out of the wall to the boiler looking to be reducing it to 12mm(??).
He is stating that with the new boiler, 22mm will have to be installed from the meter and then reduced at (or close to) the boiler down to 15mm.
I have read the install instructions for the boiler and it states the incoming has connection is 15mm and also, from the Gas Supply requirement section: 'Pipework from the meter to the boiler must be of an adequate size. Do not use pipes of a smaller size than the boiler gas connection (15mm).
Is what he is saying correct, or just 'best practice'. Is it breaking regs etc??
Thanks
Adam.
