External gas pipe

[Frazer Jolly Goodfellow]

We're planning to replace an old CH boiler with a combi boiler and it's been pointed out that the gas feed to the existing boiler isn't

22mm as required for the combi.

The gas meter is at a front corner of the house and the new boiler will be at a back corner on the same side. So to minimise the disruption to decor we're proposing to take the feed along the outside of the side wall. The side wall of the house is right on the property boundary and faces on to a shared yard area in the adjacent property so there should be no problem with access to do the work

Would running a gas pipe along the wall be acceptable per whatever regs apply?

What type of pipe and what (if any) protection for it would be required (or advisable)?

Any gotchas to worry about?

[Of course, the CH engineer we choose should be able to tell me the answers, but I'd value independent expert opinions in advance]

Copper is commonly used. (Do gas fitters still fit iron pipework?)

Yes -- with the high price of copper, people are finding external copper pipework gets nicked in some areas.

Is there no equivalent of armoured leccy cables that could help reduce the risk of vandalism/theft/accidental damage to an external gas pipe? Or maybe trunking to protect the pipe?

[Andrew Gabriel]

Yes, iron pipework. However, I haven't seen a gas fitter use it for decades. Hence my earlier question about if they still will if asked.

Some will, but it requires a few specialist tools. Not something that a lot of your run of the mill domestic fitters will be able to do either. Generally a commercial outfit will do iron\steel pipework.

Thanks for that. I'm happy that there'd be no problem in principle

Unfortunately, hearsay and recent news items re theft and vandalism of external gas pipes are putting us right off that option e.g.:-

Can anyone suggest an effective and affordable way of securing and/or concealing the exposed pipe?

If you read back through the thread 2 of the most cost effective and commonly used methods have been suggested.
