microbore to 15mm ?

[boggeddown]

Hi all,
I've been asked to relocate 3 or 4 rads that are currently supplied by microbore pipes (8mm I think).
After moving the rads can I install the new pipe work in 15mm and then just re-balance the system ?

It's an open vented c/h stystem with f & e tank in the loft.

thanks in advance

Would be better.

You could for ease and speed use 15mm barrier pipe, and use 15mm copper tails to the rads.

id prefer to see coper all the way, nothing wrong with 8mm or 10mm. why do you guys insist on running it down?

Im not knocking it Mark, I dont use it.
Would replace in copper myself, having said that this is a DIY forum and a novice would find plastic easier, would,nt you agree.
