Radiators not heating at bottom

travel_freak

Hi,

I have several radiators which seem only to be heating up at the top, whilst the bottoms remain cool/cold. Please does anyone know what might be wrong and how I can cure this?

Many thanks.

if you have bled them then you will need to ad a system flush additive, let it run for a few days and then drain and add inhibitor

Sounds like you need to flush out the sludge, using something like Sentinel X400 here.
