Radiators do not get hot at the top

[daisygal168]

I have Worcester combi boiler and am finding that my radiators do not get evenly hot throughout. They are either luke warm at the top or the side. I have tried bleeding them, but no air comes out.

The pressure guage on my boiler is broken.

I have filled it with water, but am not sure how much to let it fill and not sure what the consequences would be if the pressure increases too high.

Is it the pressure which is causing the radiators to be unevenly heated?

thanks in advance.

No. It's the crud.

How long lived there?

Age of system?

Any inhibitor in it?

Most recent work done?

Any other problems with the system?

thanks both!
I have just filled up the water in the boiler to a count of thirty seconds and have managed to bleed all radiators till water came out- which was perfectly clean.
Now to the pressure guage... Can I fit this myself, or any idea how much it would cost to get this fixed?
thanks
