i am currently using Boilermate 2000 with switch version hot water tank, in last 3 weeks my hot water tanks started to make horrible noises e.g bubbles and banging noises, I have got still hot water and heating is working. I called British Gas engineer 3 times for repair, they came to checked my boiler and Boilermate 200 hot water tanks, they said that all system working fine, nothing wrong with boiler and hot water tanks (they didn't charged anything), they noted that in system/pipe, there is a air is stuck and advised me to take air from radiators I did this but it didn't work.
My question is that what else should I do stop this noise and I'm living Nottinghamshire area a part from British Gas is there any other company can solve my problem.
