On both of my radiators that fit underneath bay windows, the bottom half
of
the radiator in the middle (long) section does not heat up. Both ends of
the
radiator, and the top of the middle section does get hot.
Does this indicate some sort of blockage in the radiators?
And if so, what would be the best way to relieve the problem?

Thanks
Paul


That would be sludge then.
Remove radiator, take outside, and clean out with a hose until it runs
clear.
Repeat for every affected rad in the house.
Watch out for spills of dirty brown water on carpet when removing.
