which order do you pipe up boilers?

[kay-jay]

just wondering which order you pipe up boilers in? and if there is a reason?

my own preference is to work left to right or right to left depending on situation as i find it quicker and easier.

boss keeps trying to drum into me to do gas first, then a tt can be done while the cold water is piped, allowing water back on quickly to rest of house. then any order for hw f and r, i don't like doing this however as we fit a lot of vaillants and i find it awkward to tighten up the valves when not working left to right as its hard to get tools in between two valves on most of vaillants.

just wondered what you guys do and why?

depending but i normally do cold first if we have supply turned off. no reason not to be able to use toilets or get kettle on then. also depends on the routes after leaving boiler

 

[grahamgas]

Normally the cold first, then gas, then everything else.
Unless it is on a boiler that makes it impossible to do it any other way than left to right, or right to left.

On the oil side I always like to sort cold first, as Bod says 'kettle', then depends on boiler and pipe routes.

 

[mutley racers]

am pretty sure vailiants tell you to do gas first and then work your way out either way, so you can do the fittings up without a struggle

I fit a lot of Vaillants and usually do gas first but it depends on the position of boiler, e.g if its hard up against a wall then I work out from the wall.

Whatever way they fall. No fixed order. Get the right tools and you can get them in anywhere.
On a swap i don't know until i look at it. On a new install it doesn't matter.
Always fill the kettle before you start and i only drink it (usually lukewarm - cold) if it is made for me :wink:

I like to get all pipe in dry and then when happy with layout get it all soldered up. No particular order thou

Recently I purchased this Armeg Combi Spanner and I've found that it makes tightening these Vaillant valves up, so much easier. You can get around half a turn and the other valves don't came in the way. Its definitely a must have tool for me, it saves time and results in less fiddling about. Its good quality as well, nice and thick, not like the Monument compression spanner.

I usually do the gas first and then work my way from one end to the other.

I often do the flow and return first! 22mm so easier to bend 15mm over the 22mm rather than vice versa if you've got swap over's. Then gas then hot & cold last. Waters off for an hour but i've normally got a flask in the van :angel_smile:

yeah thats my way of thinking too, always easier to cross 15mm over 22mm rather than vice versa.

straightforward system conversion yesterday, installed a cheap alpha intec 30 c in cylinder cupboard. first time alpha install found it ok but not sure about the telescopic flue. it is only taped up around the joint and the joint is in the cored cavity so a faff to check on future services.

nice running trap in the condense flexi

lol, that disappeared when the fitting was pushed flush with wall. at that point the external condense was just poking thru the wall as was the blow off. ideally would have cored lower down but other side of wall was extension with a vaulted roofline, hole comes through on outside just above the lead weathering, a case of needs must....

 

[GQuigley67]

i do all 22mm pipework first then the 15mm pipework

 

[SafeGasInstall]

gas first then tt , before fill up just to make sure have not cross the 22 mm pipe work lol

i pipe them all different it is all down to of how much time i have on the job

 

[Dannypipe]

Often will do left to right but don't have a hard and fast rule.

I just try to give it a bit of thought so it doesn't end up looking like a musical instrument.

 

[AWheating]

if i have to cross pipework over then i normally do the 22mm first, then 15mm as its easier to bend/cross over. I do like to try and get the cold water on as soon a possible.

If the boiler has a jig i now normally fit the boiler to the jig first then pipe up, unless im running pipework down the back of course.
