Installed at the moment is a standard none condensing boiler, on a kitchen wall and working absolutely fine - supplying heating and hot water via a tank, with the usual header in the loft.In my absence an installer has been along to price up for replacing this boiler with a new condensing type, without specifying make, model or even the type - though I would assume the type will be 'regular'.As part of the installation the installer has quoted for the complete replacement of the gas supply pipe all the way back to the meter, with no explanation as to why this might be needed or necessary. Obviously I am rather puzzled, as the existing pipe is not that old, put in during the last major refit about twenty years ago and I would have thought perfectly adequate. From memory it is 22mm from the meter to the corner where the boiler plus cooker are, then drops down to 15mm for the final 1m or so to the actual existing boiler.Mentioned by the surveyor (all second hand information) was the running of the new pipe around the outside of the house.Now before I start shouting expletives at the surveyor down the phone, I would appreciate some comments first on the above.

Our old non-condensing boiler had 22mm for most of the distance, then 15mm for the last 2 metres. The new condensing one needed 22mm throughout, so the guy just replaced the 15mm part. That seems fair enough - if that much gas is needed at time, then so be it.Perhaps he's trying to factor the cooker out of the equation because thepressure at the boiler would fall below minimum if the cooker was in use. Or perhaps he wants a less obstructed run to keep the pressure higher.(I am not a gas engineer; these are just my observations and what the guy said to me)

Boiler swap?

Sad. But it's not too late - don't let a relapse ruin things. Get back into rehab immediately.

Anyone who knows anything about gas supplies calculates the size of pipework they need, and has a good laugh at your postings.

I said....."Anyone who knows anything about gas supplies has the boiler on its own independent gas supply." Got it, Amateur?

Obviously you don't understand 'independant'. Look at my posts - it will give you a clue.

Only rank amateurs give advice which is misleading.
