In a flat - all our radiators are hot at the top and cold in the
middle and the bottom.

I have been told this is not a trapped air problem - as they would be
cold at the top

We have a non combi boiler

Can anyone help come up with any ideas before I call an expensive
plumber

ie - how to flush radiators, or balance them????!!

Thanks

Rob

Pour this ( http://www.toolstation.com/search.html?searchstr=81717 ) or
something similar into header tank and leave for 2 weeks, radiators should
start working slowly.

empty system and refill could also add

mind

Total cost £15, plumbers power flush depending on plumber £80 - £150

If it's really bad as you say all the rads are cold at the bottom, then
would drain the system, remove all rads wash out with hose pipe, replace
then add system cleaner for a week, drain and refill.
