I have a Glow Worm Flexicom 30CXi Combi Boiler, 6 months old. It used to be silent, but recently, when it ignites there is an incredible 'bang' which resounds through the unit and through the flue pipe to the outside. It is so loud it sounds somewhat like a car door being slammed shut.
Is this due to the gas settings being wrong, or is this normal for a Combi Boiler?
What else could be causing this loud bang?
Thanks
