    here are a couple...

    great articles... http://www.heatinghelp.com/article-categories/332/Gravity-Hot-Water-Heating

    generally speaking you can cut your piping in half and then reduce 1 pipe size. So 1" will work. DONT over pump it! a small circulator will work fine. you are trying to mimic the gravity flow.

    didn't new boiler come with circulator?

    Use transitions from new small pipes to old large. Supposed to be better than simple bushings. Biggest issue is expansion tank. If it's open you may want to consider closed.
