Gas pipe to kitchen island

[bopster]

Hi there, newbie here so please don`t bit
I`m about to have an extension built on my house enlarging the kitchen. I`m going fit an island with 6 burner gas hob fitted in it and wanted to know the best way of running the feed pipe. From the existing concrete slab up I`m fitting 35mm profiled UFH with travertine tiles ontop of that. Should I simply use a 22mm copper pipe slotted into the 35mm insulated ufh boards or use a pvc coated 22mm pipe cut into a groove in the slab with the ufh boards ontop. The island is only 3m from the external wall and the gas meter is then only 2m away My Gas safe man will be making the final connections.

Hi.
You should speak to your gas safe man, he will make the decision on what material to use and he will need to run the pipe himself as it is part of Gaswork.

I'd fit a 100mm duct under the insulation with slow bends either side, then you can pull plastic coated copper or trac pipe when you're ready.
HTH..

Richard is of course going for the high cost option.

Tracpipe is about three times the cost of copper!

The gas reg installer will advise and copper is the most economic material!

a good qual hose pipe will slide through a 40mm waste pipe sleave easier

The green ones kink too easily.... the Yellow ones spring back much better .

Damn Tony, you've rumbled me again!!
Also, copper has a better flow rate & maintains less of a pressure loss too......

I only eat the green ones.... Yellow indicates I'm suffering from Man-swine-flue and therefore need to increase the Gin intake.

Had to re-run a gas supply after a boiler install last year (not the AquaNova CC boys!!! ). Tracpipe worked out cheaper than copper once the labour was taken into account.

Oh it can indeed Dan, but be careful, the pressure loss on trac pipe is sh.te compared to copper & the fitting can leak like a sieve. Don't believe their sales pitch!!

The above is purely my own personal view, my views are not as that of the forum or any other forum member and are written without prejudice.

Thanks for the constructive help lads lol
Maybe I'd be better off using flexible galvanised 20mm copex than hose though as wouldn't it have a bigger internal od and have the bonus of swirling the gas so creating more of a whirlwind effect at they burners?

 

[Richardthe3rd]

Happy to help.
We did drugs that made things swirl like that in the 60s. LSD groovy man!!

 

[bopster]

Wasn't around in the 60's but the 80's certainly held no shame for me lol.

Just wondering can you chase a black iron pipe into the floor?
