Hi Guys,

I have a three-year old Ferroli Modena 80E combi boiler. From last few hours, I am listening to the strange whistling noises, which are coming directly from the boiler. The sounds are extremely loud & last for a minute or more. What is the wrong with the boiler?

Thanks

Matt

Hi Matt,

Normally, you will hear these whistling sounds when air badly trapped in the boiler. Although, low pressure of the boiler and kettling are equally responsible behind the whistling sounds. A damaged or faulty pump can produce difference annoying and strange sounds. Luckily, it can be fixed effortlessly once you bleed the radiators the pipes. Anyhow, if your problem persists, feel free to seek guidance from a skilled boiler engineer.
