I've been having trouble since I had a new boiler installed. It's a combi installed in a conventional setup with a hot water tank, gravity fed from a cold water tank.
When they installed it I got a power flush and the radiators bled. Initially it sounded like rushing water in the system so I had the installers back out and they said there was air trapped, so they fixed that and it was fine for a week. Now today I'm hearing popping/cracking from the radiators around the house. I recorded a sample audio which you can find here:

Is this likely to be more air trapped? The radiators were bled last week and trapped air released after that, so if it is air what might cause air to continually get trapped in my system?
