Can you help,
I have recently had my boiler serviced ect and had to extract some water from the boiler so I could put x100 and x200 into the feeder tank in the loft. The tank did fill up again and everything was fine. I then noticed that when the boiler is heating the hot water and only when it is firing up to heat the water , there seems to be alot of loud banging from the boiler. There does not seem to be the same problem when the the boiler is on heating and water.
