system boiler, gravity system and pumped heating (primatic cylinder). complaints of noise when boiler goes off, tested a few times nothing happened, there should be a pump overrun on there (or only for fully pumped systems).

i could not find a fault put it down to sludge in the system and ideas

if it is a cbi 14/19 it is not suitable for gravity installation fully pumped only and yes it does have a pump overrun.the sys boiler is the sbi

here is a bit of info

My thoughts as per bripl:

Great boiler, but not for this system.
