Ferroli Combi Boiler noisy central heating pump

Hello Guys,

I have purchased my Ferroli combi boiler two years ago. I am here to share a problem regarding the boiler. My boiler makes a loud and strange banging sound whenever I connect it to power. The boiler bangs after a second. It sounds quite weird. Someone please guide help in fixing the problem.

Thanks a lot

Nick,

Hi Nick,

Some possible reasons behind the noisy central heating pump are as follows:

  • The shaft of the central heating pump is not leveled
  • Air-locked
  • Choked with dirt
  • Seized Internal parts
  • Wrong settings of speed

It is better to contact an expert boiler engineer for detailed and safe investigation.
