Hi, new to forum and would like a bit of advice if possible.
I have a heating system and a plumber has said I need to increase pipe diameters.
I am confused by this as I can not make numbers stack up to justify the diameter increase.
I have a 22mm diameter feed into a manifold which has 4 16mm diameter pipes feeding radiator network. Each branch has either 3 or 4 radiators on.
The valves on radiators have 8mm internal opening.
When I crunch flow and velocity through pipes etc the total still I'd greater than supply.
I can not understand how increasing from 16 to 20mm will improve system as radiator all heat up very quickly with current configuration.
Cheers
