    Thank you for the posts, looks like I have everything under control for now I did everything that you guys suggested, plus i had almost new Grundfos circulator from old boiler so I have swap cartridges from regular circulator to stainless casing of the existing pump (I hope this is ok). Bleed the system and runned for .5 hr no more noise-silence is golden. My hydronic system with heat exchanger was never flushed after initial flushing @ time of the boiler replacement. There is lots of magnetic debris-rust any suggestions ?
    Thank you guys for all the knowledge and help.
    Ps: There is two pressure/ temperature gauges, one for boiler loop and one for heating side. Both read about 20 PSI Hot Thanks

    Thank you for your comment. It makes lots of sense now. When system was coming on for a split second I could hear sound like some thing was gasping for air in the proximity of the Spiro vent. It did not make sense to me because Spiro vent was installed to get rid of air and dirt. After two years I still have lots of rust in the secondary loop, the heating, baseboard side.
    Thanks again
