Radiator vents

Is it advisable to plug the air vents on each radiators and vent only on the main located near the boiler to increase efficiency of a two pipe system?

    Pictures of a typical radiator showing each end connection would maybe give the answer.

    There aren't many two pipe systems with vents on the radiators. Were those vents added by someone over the years because traps had failed? Pictures of a couple of the radiators and both connections will tell a lot.

    pics of the boiler and rads would help

    Most likely....yes. There are a couple of two pipe systems with vents on the radiators, but most likely you do not want the vents on the rads and should have traps on the return side of the. The air will vent through the trap, follow the return back to a vent in the boiler room. That being said, as others said, get us some pictures and we can tell you for sure.
