Thanks Terence,
But I don't actually have a blockage, just a noisy radiator, as if something is rattling around inside it or it's bubbling with air, and I have to bleed quite regularly.
I haven't tried to capture the gas on the overflow yet but I tried to ignite what came out when bleeding the radiators, as far as I could tell it didn't ignite.
On the noisy radiator I opened up the lockshield slightly on Saturday, this did quieten it down a fair bit, I haven't tried opening it more as I don't want to affect the balance too much.
What I don't know is why it's made it a little quieter opening the lockshield
Like you said, it can't hurt, plus I've just fitted 2 new towel radiators, one in the bathroom upstairs and one in the toilet downstairs so it's going to need a treatment anyway
