Laars Endurance boiler noisy pipes

Hello Everyone,

My newly bought Laars Endurance boiler is producing some strange banging/hissing noises. These sounds are coming directly from the pipes. I have tried to fix the problem after reading the user manual but all in vain. Has someone faced this issue? If yes, then please guide me

Thanks for your suggestions


Hi Alex,

This issue could be because of the following reasons, which generally results when boiler overheats. It is better to get your boiler serviced regularly. Well, coming to your problem, the reasons behind this issue are:

  • Limescale buildup
  • Inadequate water in the boiler
  • Blocked chimney
  • Faulty thermostat

Well, you cannot fix this issue on your own. You have to contact an experienced boiler engineer in order to have an in-depth & systematic investigation.
