Hi I have a BAXI Bermuda 552 Boiler and the hot water heats up fine although the noise through the pipes is a bit loud - the radiators however do not get warm - I have bled all the radiators also and found in the airing cupboard that the lever on the Motorized Valve is very loose and doesn't make any difference when slid from left to right? - Could this be the problem and a new valve is the answer
