If your boiler has been producing unusual noises regularly, it could indicate that there's a problem. These noises range from whistling, rattling and clanging sounds. What could cause them? There's actually several possibilities for your boiler producing strange noises;

  • You boiler could be suffering from an inefficient fan.
