I am not hiding just being busy before Christmas. Trying to do as much as I can but slowing down now as it’s getting closer to Christmas. Scheduling works for new year. How have you been ? Aren’t you busy before Christmas, I bet you are 🙂
Lucky enough to be busy most of the time mate. But I like it on here and find it quite addictive. Looking forward to Christmas though.

I find it addictive too ... but sometimes I feel like people come on here to wind us up ... I don’t get the impression that they really need help but trying to fool us. I can only admit I like it too and it’s a great thing to share knowledge.
 
hi, whats your water supply pressure and flow rate?

assuming a combi.... 22mm flow and returns 15mm off this to rads (maybe 10mm in walls if rad is not a great output) 15mm hot , 22mm primary cold 15mm to fixtures(best first tee to feed combi)

gas must be sized and installed by a gas safe engineer. boiler must be installed by a gas safe engineer. (including fixing to wall)

Hi and thanks for the advice.
I should have made it clear at the start i guess... I have someone to do the installation for me who is gas safe registered.
I just wanted an independent opinion on whether its best to use copper or plastic. and as I am supplying them with all materials I need to know how much pipe and how many fittings to get. Thats why I did the drawing to see how much pipe i would need, just not sure if it is the best way to run the pipes?
Thanks again...

Most plumbing and heating suppliers will supply you with a heating pack which will contain all the main components fittings ,and pipe you need , if this is new build then its plastic under floors and where not visable and copper on show. Refurb then you can get away with copper which in my opinion is far superior. Kop
 
As above really. Copper is by far superior and when installed I would won’t to make sure it’s will be insulated with armaflex. If you use plastic then I would only use crimping rather than pushfits. Me personally I would use a combi storage boiler rather than an unvented cylinder but that’s preference. If you ask plenty of plumbers you’ll see that everyone of them may have a different idea of installing such a new system.

plastic costs more for materials but labour is alot less. also most newbuilds are done from below in ceiling for health and safety and constructions reasons. most joist systems make it very hard to install lengths of copper without damage.

the only new builds that are normally all copper are one offs and national trust type housing associations.

Why can't you get away with copper throughout on a new build kop?
you can bud but if you have to go through joists it's a nightmare of a job pricing against the plastic boys we will be alot more expensive sometimes you need to match your competitors
