    What is the system

    pressure? Do they have zone valves or circulators? 



    You said you bleed the system, was there air in the systems? Typically bleeding is not necessary on a system which has the PRV working correctly and has not been opened for any service.



    Any idea were the noise is coming from, piping, boiler etc?
