Hi,
This boiler was installed in my home about 6 years ago, when the houses were new.
Each time it comes on there is a distinct whistling noise coming from the boiler - it is similar to that of a car driving quite quick and the slightest opening in the window makes a high pitched noise.
A friend of mine (plumber) fitted a device that gets rid of air in the system and we also got rid of any air in any of the radiators.
I noticed recently that the water in the radiators was a blackish colour also.
Any advice appreciated.
