Last summer I've installed vertical radiator (Hudson Reed Revive Vertical) but its not performing very well. After reading many topics and googling a lot I've found out that I need "flow diverter" which wasn't supplied with the radiator but I can't find place to buy one.

Can someone help me please...

I've searched for long time but can't find what I'm looking for, maybe my description was wrong.

the thing I'm talking about is a piece of plastic you put inside radiator to prevent water from taking easy route and forces it to go up and heat the radiator.

at the moment flow and return are very hot but radiator just warm (even with all other ones closed) it gets hot for a moment only when I disturb water flow by changing water pump speed or close/open by turn or two return valve.

its different radiator but idea is the same (component C)

just to be clear radiator is not fitted upside down...
