I'll try get some pics of the system tomorrow, depends what time I home. Gotta big disinfection job at Porton Down tomorrow. But basically, its a big old oil fired boiler on the ground floor and the header tank is 2 floors up in the roof. All the other rads around the house are all nice and hot, just the one with an issue. Cheers

going off the latest info, a blocked cold feed is looking likey, a little bit is filtering through as the rad is getting heat further up, with luck it will get further and further, but if it is a blocked cold feed, the first tee is the likley offending joint,
stand by tomorrow with a magnet,,,

Quite a few years ago I can remember going to a attic radiator job that wouldn't vent. A previous plumber had raised the header tank another 18" (as high as it would go) yet this attic radiator still wouldn't vent (all the others did) and the problem continued. The solution was quite simply to switch the pump off before you vented the attic radiator. I reckon the climb up 3 flights of stairs to the attic radiator to try and vent the radiator had the previous plumber so bushed that he discounted the pump on theory! He couldn't be bothered to go all the way back down the 3 flights of stairs to switch the pump off, back up again to vent the rad and then back down again (phew  ) to switch the pump back on, then up again to test it (hey plumbing's not an easy job )!! I suppose this true story is a kind of proverb with the meaning being "Don't be a lazy plumber"? Tappy,  |

Update
Its sorted, turns out its a sealed system. I took the front cover of the boiler and there is an expansion vessel, so I rooted around a bit in there and found a filling loop. I repressurised the boiler and bled the radiator, and got water after a few seconds. All heated up nicely. But I'm left more confused in what the f & e tank is for. Could that be for the hot water system? That is heated by a normal cylinder and immersion but also from the agas back boiler, but i'd have thought that would be a sealed system. Thank all for the help.

It sounds to me Lee that you have a tradition hot water system with a system type boiler,the heating is presurized but the hot water is fed from a tank, Its all very normal if you have a aga, they need somewhere to expand to, when they are lit you just can't switch them off, But anyrode, glad its sorted,,  |

Its a relief to be able to start making sense of this system Tom. Ive only lived in houses with combi boilers before this one, and at work its all Legionella control on commercial hot and cold water. I think I need to learn more about heating though. Cheers for your help.
