I've had a Worcester 34 combi classic fitted a few weeks ago and ever since have had air trapped in the system that I can't shift no matter how many times I bleed the rads. Before I call the installers back is there anything else I can check?
There's no apparent leak and it sounds the worst when the boiler hasn't been operating for a few hours. Really sounds like someone filling the system from scratch!
