gas pipes question

[timmyag]

hello all I’m new here

have a reasonable background in electrics but know squat all about gas

am having a extension and am going to have a new combi boiler as part of it, as I’m currently chasing lots of cables, and would also like to chase slots for the gas pipes, as i don’t have to pay me.

what i wanted to know is sighting a boiler complicated i have a bit of wall in my new kitchen under a flat roof where it can be flued. is my installer liable to say he doesn’t like the spot for something I’ve never thought of?

also I wanted to know what regulations/good practice is there for burying gas pipes in walls, do they have to be a certain depth? at certain heights? how much room will an installer need to do the soldering? Do they need a certain size or type of conduit ( I assume 22mm pipe is in order)? Im looking at about 6-7m from my meter to the boiler could do it with only 4 90 bends if it ran all at the height of the meter or boiler but don’t know if my installer will look at it and do it again himself if I did that.


lastly has any one any experience of the Chaffatoteaux & Maury HE 30?


I know I could ask when I get the quote but is so much easier to explain if what I’m going to do is done when I get it.

Thanks a lot
Tim

Whatever you do get the CORGI registered installer to agree with you where the boiler should go.

There are a lot of regulations to follow!

Although I don't know this particular boiler, I used to install quite a few C&M Britony combis and have subsequently maintained them. I think their main virtue is being cheap. Reliability is not good and the plastic components sometimes had pinhole leaks! Unless they've got their act together recently, I'd give them a miss.
