Hi there just need some advice regarding a radiator in our master bedroom. Its an old type of radiator and its not warming as much as it needs to be. I need to bleed it all the time just to somehow increase the heat. Everytime I bleed it a lot of air is coming out followed by black stuff then water would flow and will clear up. I need to do it everytime I turn the heating on. Every radiator in the how seems to be working well and theres not much of the black stuff and water would flow fine. I just also found out that my boiler wasnt serviced for quite a while before we bought the property last year. I want to know if do I need to replace my radiator and what type is the best as I want to change a few of them as they are dated. I would have my boiler service soon and just want a piece of advice so I could include it in the budget. My boiler is a Baxi Bston 2 RS floor standing room sealed,gas fired central heating. Its an old type with a water tank upstairs.

Your advice is greatly appreciated thank you.

just cause that rads getting air in don't mean its a fault with the rad.
could be the systems drawing in air through the vent pipe etc or the system needs a good flush through.

Thanks for your reply mate. So I really need to have my boiler serviced soon. Do you think if i change the boiler will it make a difference with the heat as our room is too warm compared to other area in our house. Will flushing cause me much. I'm from the Boro and dont know how much will it cost here.
