Radiator Manifold question

[Jamesplumber92]

Hi, if you're installing a manifold to serve each room as it's own zone can you join all rads in that zone from the same port on the manifold?

For example, I've got 14 rads downstairs, there is 2 in the living room. My manifold ports are just 16mm, can I run pipe from 1 port to both these rads?

It'd mean I wouldn't need as large a manifold, maybe it's defeating the purpose by making joints in the floor though

I can't see a problem with running two radiators from one port provided the pipe sizing is sufficient for the flow required.

What's the total output of the two radiators? I can't see it being a problem.

Nothings sized yet, just wondering how I'll pipe it

I cant see two rads coming off that one loop being a problem, providing you don't have ridiculous heat loss. You really need to do the calculations first though so you know what's required and how to approach.

Depends on length (run) and size of rads

over 1.2 I would do each run to a rad
