    Other than dirt in the main heat exchanger, I could not guess.

    These are a very quiet boiler usually.

    Get your installer back to check it out.
  • Get your installer to check it with his flue analyser, I have installed boilers where the ratios are out a mile and give this sort of sound your describing.
    It be the first thing i would check but he should of done this when he commissioned the boiler.
  • I had a similar problem once, it was the heating pump causing cavitation in the pipes. Basically too big for the system.
