Seem to be getting an excessive amount of air in two radiators, need bleeding every couple of weeks. Boiler is two years old and a Worcester combi. Any ideas?? Didn't have an air issue before.
Get a Tupperware dish ( not a glass dish) and bleed "air" and hold upside down dish above so it collects in it.
Take it outside while still holding it upside down and then light it with a match.
If it lights with a pop it's hydrogen.
You can directly light it coming out but it goes like a flamethrower and can light back to inside rad and go BANG so not recommended.
