Extra rads

[Unregistered]

I need to fit an extra 6 rads to my existing combi ,it is a one pipe system.
Is it ok to mix one pipe and two pipe systems?

Its best not to mix the systems but ive seen it done, for a combi the system is normaly two pipes and this is the best one to have
can your combi take another 6 rads?????????
