New pipework

[confused 2]

I am looking for reasurance really,
I have just piped up a new installation [Bungalow],
needing to avoid breaking through a DPM I have ended up with a 3 branch layout in 22mm with 3 other "smaller branches in 15mm off the 22mm, 10 radiators in all which will be fed by a Combi in the loft, does this sound OK as one person told me that it would not work because it was not piped as as "ring main" type layout.
Hope I have given enough detail if not I am sure you will tell me.

Sounds OK. Ring mains are applicable to electrical power circuits, not hot water heating circuits (except for old fashioned single pipe systems).
