BOILER PIPEWORK NOISY ON HEATING CYCLE.

[alan48]

NOISY HEATING SYSTEM.

Morning all, I have a heating system, installed about 3 years ago and its quite noisy, boiler is first floor above lounge and when sat with the system running the pipe work seems to generate a fair bit of noise, so my question is if I lag the pipe work would that help deaden the sound of what appears to be water being pumped round the system.
Boiler Vitodens 111-W

Hope someone can help, many thanks in advance.

What type of noise is being produced? Check any TRV’s that are fitted, es any that might only be for one direction.

Thank you for your reply, all TRV's were new at time of install, all rads heat up quite quickly, how do you check for one direction valves though?
The noise is like a low rumble, not very loud and only lasts for a few 2 or 3 seconds, boiler serviced by Viesmann and I have mentioned it to service engineer but nothing has changed.
