change routing of internal gas pipe

[bananaspark]

The previous installer of the CH system in my house routed gas to the combi from the meter (15mm cu), up through about 10 metres of pipe and associated elbows. It is exposed on the landing along with all the CH pipes and I dont like the idea of excessive joints on pipes.

I've spotted a way to connect to the combi (currently out of service and disconnected until a gas chap comes in to fix it) from a 3/4 steel female capped elbow that was hidden inside a kitchen stud wall, presumably for a cooker. This could connect to the combi with a single 2m unbroken run of copper pipe.
I'm assuming that the gas installer before either didnt see this shortcut, or had good reason not to use it.

opinions?

Did you say 10M of 15mm copper?

 

[gas4you]

If you have 10M of 15mm copper plus loads of bends then either installer was not CORGI or a muppet

Do you actually get plenty of hot water?

You will need at least to have it changed to 22mm copper all the way, maybe even some of it at the start in 28mm depending on output of combi and number of elbows in the run

What size combi is it?

It seemed to be all working fine when I moved in, it's a 22kw worcester bosch I think for a small well insulated 2 bed 1 bath pad, though I will be installing wet underfloor heating in 3 rooms in a few months time so maybe need to get a condenser later on...

Having said that I never got a chance to put the gas cooker on with all hobs blazing at the same time as running h/water but guess there was no problem there either - it all seemed to installed 8 years ago.

will running 22m from the steel make a difference as it would still go through the coupler bottle neck - a plumber told me that 3/4 steel is internally the same diameter at 15mm copper when he came to freeze the steel 3/4 water main and fit a stop.

28mm is 1 inch I take it, that is coming from the meter and goes down into the concrete floor where it branches of into the 2 x 3/4's seen in the kitchen and 1/4 inch for the living room gas fire.

an incredible bunch of b*llocks about gas and gas pipework

Why are you getting involved with gas when you barely have any grasp of what you're talking about?

[clf-gas]

Must have had two to many fairy cakes softus, still cant see that quote

 

[Softus]

Well I might be able to clarify it, but what's all this about a cake maker?

 

[clf-gas]

A North manc expression for an easy opption. Or a lazy barstuard.

Oh, ok. Well, my post was an opinion, which the OP requested, and was particularly based on the following revealing snippets:

28mm is 1 inch I take it
