Very Loud Banging

[Shirl]

About a month ago we had a Worcester Combination Boiler fitted (we used to have the old system with a cold tank and a hot tank and water pump with a back boiler fitted with the gas fire), anyhow, about two weeks later I heard very loud banging, as though someone was drilling out side but in here, I went upstairs and it was in the back rooms near the radiators, I thought it was air in the pipes so just switched the hot water on and it stopped, I turned off the hot water and it started again, I had to turn the central heating off.

I turned the heating back on the day after to see what it did and it gave me 10-15 minutes and started banging again so had to turn it off.

All the radiators were hot although the bathroom one was cold but we bled it and its fine now.

Any advice would be greatly appreciated.

Could be thermostatic radiator valves?
