Extend Feed-and-return system with manifold/microbore?

[luan_au]

Hello Folks,
Is it possible to do the above? My existing central heating system is a Feed-and-return type with a combi boiler. I'd like to add an additional radiator in an extension. Could I add the new radiator using a manifold and microbore or plastic pipes ?
Regards,
Luan

why use a manifold for one radf ?

PLastic pipe is generally fine - diameter depends on load and distance.

Use 10mm Hep2o barrier pipe and just reduce of either the main 22mm or 15mm flow and return pipes with tees and reducers.

Many thanks for your replies.
The reason I am thinking of using microbore/manifold is ease of installation really. I just imagined it might be easier to run flexible or microbore pipes under the floors. But if you guys know a really easy way to add an extra radiator I'll be very grateful.

You just was gived one innit? Depends on rad size and distance though.
