I had a burst pipe in the house on weds and a plumber had to do a drain down to repair the leak. My boiler has now started whistling when it gets warm. This whistle has never happened before and it started on Thursday.
Will it sort itself or will I need to get someone to look at it and is it ok to still use my heating?
ask the heating engineer back to check, in fairness to him it may not be caused by his work, fans whistle sometimes or he may need to do more venting of the system, if he is a decent tradesman he will return to make sure and advise
