Hi, Hope you guys can help.

This winter my radiator in my bedroom doesn't heat it up properly, it is warm at the bottom.

I initially bled it and as we have a combi boiler, after I had to bring the pressure up by opening a valve near the boiler. But that didn't work it remained cold.

I then switched off all the radiators in my house except the faulty one in my bedroom. (However the one in the bathroom didn't switch off properly and remained hot so not sure if this affected it). I then bled it again a bit. After this I think the bedroom radiator did get a bit warmer (the warmth spread), but still the whole unit does not get hot.

The water comes out a bit dirty and smells. Could it be rust in the radiator stopping the water spreading properly in the radiator? Help. Is there anything else I can do? Or do I need a plumber to flush it out?

Thank you so mch

Is one of the pipes leading into it getting hot.Does it have a thermostatic valve fitted if so the pin could be stuck.If its getting warm at the bottom but not at the top it is full of air.When bleeding turn the boiler off whilst bleeding,then turn it back on.It could as you say be full of sludge and need flushing out.Make sure BOTH valves are turned on fully as the lockshield side may be virtually off and that is just the same as turning it off.
