For many months my boiler has been making lots of howling and flute noises. The last two days this increased and now there is banging and knocking and kettling. I trust this is caused by the 25 year old exchange heater. This is not a job for me so called an engineer who will be coming tomorrow.
I would like to hear your opinion. Is it better changing the exchange heater or flushing it with chemicals? From our conversation, always if I'm right with my diagnosis, he does not recommend changing it because it will lead to more future trouble, such as leaks.
Thank you so much.
