Gas pipe outdoor?

wah3344

Hi

I am getting a new boiler installed (replacing a combi boiler), but installer says the need to replace the old gas pipe from the celler so that its 22mm. The quickest way to do this seems to be to take the new pipe around the side of the house into the kitchen (so that we don't damage the floor tiles).

My question is, should we do this? Does is go against any regulations?

Thanks

Yes, unless you could get away with a 22mm hole in the floor behind cabinet/cupboard.

No.

There is no problem with running a gas pipe outside.

A lot of houses today have had the gas meter fitted on the outside of the house and the pipework run along the outside wall.

Some one capped off and stole the pipe outside a relatives house recently.

Thank you all for your replies. Shouldn't be a problem with being stolen as its at the side & back of the house.

my gas meter is ouside next to the back door. and the pipe to the combi boiler runs up the outer wall to the 3rd bedroom. the boiler is inside a wardrobe/cupboard.

(3 bed semi).

No reason it not being run outside... One or two things to consider though

Normally when a gas pipe goes through an external wall it would be inside another piece of pipe e.g. hole in the wall short length of 22mm pipe through hole and 15mm pipe inside that…

It may be that the longer run of gas pipe causes problems flow, pressure etc …?

Best ask the installer as to why he has chosen that route sometimes people just miss the simplest route?

I had a back boiler replaced and the most practical place to fit it was in the loft. They ran a 22mm gas pipe out through the back of the kitchen cupboard and up the outside wall straight up into the loft.

All inspected and no problems since (3+ years).

That's how mine goes too. The meter is outside under a box on the other side of the drive. The pipe runs under the drive, through the wall and up into the loft. It then runs the full length of the attic and then descends down to the kitchen and out to the outbuilding where the boiler is. It's a lot of copper pipe!

The short section that is exposed outside is wrapped with some kind of greased hessian lagging material.

We were faced with a similar issue a year or so ago. The advice we received was that it was fine as said above, but it is not considered good practice to run external gas pipe along a wall that has vehicular access, ie the drive side of a house. Also if it runs around an external corner it is advised to provide some form of protection.

One trade name for the waxy protective stuff is "Densotape", not a requirement and I think they look better painted black.

Thanks for that. I hadn't considered the safety aspect.

The external piece is a short vertical run of about 24" or so and doesn't run around a corner. Never-the-less, it could get driven into.

I'll add a steel guard.
