air in my central heating system
 

I'm having to bleed my radiators several times a day to reduce the
banging from the pump/boiler. There are no obvious leaks and I can't
find any damp areas. Does anyone have any advice on how I could solve
this problem?

Have there been any additives added?

Is this a sealed system (with filling loop and pressure guage)
or a vented system (with a small header tank in loft)?

It may be hydrogen, not air. Next time you bleed a rad, see if you can light
the "air" coming out. If it is hydrogen then I think that means corrosion
somewhere, but I'm sure more knowledgeable people than I will put us right.

I used to have to bleed my radiators often. When I had my boiler and
cylinder replaced the plumber recommended that he convert the system to
a sealed system - ie adding a pressure vessel in place of the header
tank. Since then I have had no trouble at all with air in the system.
