Pipe size for unvented cylinder and boiler

[Stants]

hi I have an issue with running pipes ( the route )for a boiler and and unvented cylinder
1 can you combine bother together ( t one into the other)
2 if so what s the minimum pipe size for both ? As I have to either go over , under or dare I say through a steel .... it's in a loft Con
Thanks

What will be in these pipes?

What will be in these pipes?

Water and hot water
1 for the condensate pipe for the boiler
1 for the discharge/ outlet for unvented cylinder

In that case you need to make a water slide, no going down-up-down again.

Its a lot to explain why but all I'm asking is the minimum size pipe needed I would never go up , down and up it's all to do with height of the steel I put in I have options with that ( height wise )

Then I`m sure somebody with knowledge will be along once they have finished work with the answer.

Depends on distances... Or just use a pump.

expensive way to do things over £550 for a pump

you can combine them but they must be able to take the full load best let your g3 and gas engy size them as there is a formula

 

[townfanjon]

As above^^^^ the diameter of the discharge pipe is dependent on elbows and length , no one is the same .
Boiler condensate pipe MUST be run in plastic . Boilers are fitted by qualified guys .

Which ones are you planning to combine?
Are you useing copper or plastic?

Condensate Must be plastic and PRV or TPRV must be able to take the heat.
