A noisy boiler is not a good sign and is likely an indicator that something isn’t quite right. ‘Kettling’ refers to the clunking and banging noises a boiler sometimes makes when limescale builds up on the heat exchanger, causing the water to boil and expand – just like in a kettle. Kettling will cause significant damage to your boiler over time, so it’s best to get it looked at in order to extend its lifespan for as long as possible. One of our boiler specialists can get your boiler back in proper working order in no time – simply call us to arrange a free consultation.
