I have a very annoying noise that appears to be coming from the pipes in my heating system. I have bled the rads of air but the knocking noise is still there. I have also adjusted the valve leading to the rad but this also has no effect. Any ideas welcome.

Not sure of exact age because I moved to this property just over 3 years ago and the previous owner had moved out about 6 months before... but must be at least 4 years old. Previous owner led me to believe that it was quite new... but who knows! Has a digital set-up... don't know exact model and can't see a model number on it, but it is a Vaillant Combi-Boiler.
Forgot to mention that there has been a problem with the water not coming on hot straight away too. Normally have to turn the boiler on and off to get the boiler to flash up. So don't know if all this combined has anything to do with the strange knocking sounds or if this would be a separate problem.
