Hi All,

Looking at splitting a feed and return line into 2 branches.

I have come up with 2 different manifold ideas but I am wondering what would be better to get equal pressure for each.

I have actually made option A but after making it I am not convinced that it will pass through the water equally (i.e the first pipe out will receive water first then once all through, the second pipe out will get water)

As this is for central heating does it really matter? Would it mean one radiator gets hotter first?

Thanks
Mark

Its a pumped system (in the case of a combi boiler its pressurized as well) so will make zero difference, on a normal rad you with have trv (thermostatic valve) what alters the flow depending how it is set and room temp also the rad size will make a difference, as well as the pipe length

Someone more qualified will be a long shortly

Ah ok, so as it is pumped both pipes should get the same flow of water through regardless.

Thanks

Can’t tell if you have a single pipe or twin pipe system from your drawing

Hi All,
It is a twin pipe system. I implemented Option A last night and all looks to be going fine.

Thanks
Mark
