The fault
When your boiler bangs, gurgles or kettles
“Kettling”, a rumbling like a boiling kettle, is usually limescale or sludge building up on the heat exchanger, common in harder-water areas. Banging and gurgling can be trapped air, a failing pump or circulation problems.
Left unresolved, kettling makes the boiler work harder, pushes up bills and shortens its life, so it’s worth treating early.
Common causes we find
✓Limescale build-up on the heat exchanger
✓Sludge and debris restricting circulation
✓Trapped air in the system
✓Failing or noisy circulation pump
✓Pump speed or flow set incorrectly
