Benefit of plumbing central heating using manifolds

[RichJ]

Hi

 

I'm a new member, but I've actually been lurking on here for a long time:) 

 

I'm hoping to redo my central heating pipework fairly soon and just wondered what the benefits are of using manifolds on a central heating circuit rather than the usual flow/return loops 'teeing' off to each radiator?
 

Also despite looking through lots of threads, I haven't been able to work out whether it matters where I put the flow/return manifolds.

 

Being a new member, I've been slightly unclear on what I'm trying to find out. Sorry If I annoy anyone by revising this post a few times. 

 

Thanks
