boiler ticking/banging

[helptavner]

mainhe boiler (baxi) rumbling ticking noise from boiler when iburning, (starts approx 20 mins after being on) which seems to create a banging noise above (in bedroom) does stop straight away when boiler stops burning?

any ideas please

It's the water in your heat exchanger boiling - called 'kettling' for obvious reasons.

It's probably something to do with your pump not circulating the water fast enough.

is that a problem ^^^

It's not good. Could be poorly pump or gunk in system, either way needs sorting really. Was the system flushed when boiler was fitted?

 

[helptavner]

yeah been flushed twice so should be pretty clean and added a inhibitor sp

it will be having its year service soon will b.g pick up on this?

also part of there homecare so guess ill only have to pay the first 50.00 should it have a problem
