Cold Radiators

[seguniang]

I've had one radiator removed from the kitchen, after which the upstairs radiators remain cold. I've had a boiler service and at the same time they tried to resolve the cold radiators. They have recommended a Chemical Flush, which has been quoted at £580. I just wanted to check to see if any of you had another recommendation which would be cheaper. Also is there a difference between a power flush and a chemical flush?

Thanks for your help

have you tried shutting downstairs rads to push full flow upstairs ?
what type of system is it ?

The gasman tried that when he was looking at the radiators.

I'm not sure what type of system, its a combi boiler with 2 downstairs and 3 upstairs radiators.

It looked like it from my inexperienced eye. He also connected a rubber pipe to one of the downstairs radiators to allow some of the water to come out.

was the water black ?

could be an airlock. one rad being removed cannot suddenly stop all the others from warming - unless an airlock.....
