Alpha HE CB33 boiler’s burner issue

Hello Everyone,

I have bought and installed an Alpha HE CB33 boiler three years ago. It was working well until last night but now, the boiler is giving me the tough time as its burner is vibrating loudly and due to this, it is producing an extremely loud resonating sound. I have to face this issue whenever I turn it on. Should I replace the boiler or call a boiler engineer?

Regards

James

Hello James, you are facing this issue due to the following reasons:

  1. Low gas supply pressure
  2. Combustion gasses’ recirculation
  3. Gas or air adjustment is faulty

You can try the following possible way-out or else call an experienced boiler engineer for immediate help:

  1. If there is a problem of low gas supply pressure, do contact a gas company instantly
  2. If it is due to a combustion gasses’ recirculation then, you have to verify a gas ventilation shaft and air supply
  3. If gas or air adjustment is faulty, check the adjustment of both and verify the settings

Feel free to contact us if your problem persists
