Noisey column rad.

[lazeydaze]

Hi all. I’m a newb so be gentle!
I have renewed a system at home and have 2 column rads. One seems to be overly noisy and I know I connected this with flow and returns wrong ends. Rad was marked up. Would this cause the sort of whooshing noise that I have?
Can I just flip it round and refit?
Would turning pump down a notch help matters.
I have a grant 26kw floor combi
Thanks in advance.

You have answered your own question- turn the flow and return around.

thanks Andy
So you think that’s causing the additional noise? Any idea what causes that internally out of interest?
Thanks

if the flow was marked , it has a distribution baffle inside the rad, you have to connect them the correct way round

The baffle is to direct the hot water to the top of the rad, it should heat up faster when the pipe orientation is sorted
