Hydronic Piping System

    A series perimeter loop is similar to a one-pipe system with the exception that the series pipe actually goes through the convectors/radiators units and a one-pipe goes by the convectors/radiators with branch pipe lines (supply and return) to each convector/radiator. So the one-pipe would have better pressure I believe since it has the main one-pipe continuous bypassing.

    With the one-pipe, you could have a shut-off on each convector/radiator unit for maintenance without shutting down the entire system.

    Check out this description.


    Thanks for posting this, it helps me understand better also.
