water is heated. Since you are not going to the boiling point not all of the O2 will be released.

That is one of the main components in both a good hydronic treatment, and hydronic glycol... the O2 scavanger chemical. It's also the part of the glycol you can boost, with a boost additive when it gets depleted or weak.

    Eliminating Oxygen in low temp radiant system

    I'm cleaning my radiant system right now and plan to add their anti-corrosion treatment after everything is flushed out.

    Without the additives, will just a normal vent get rid of the oxygen in the water if the temp never rises above 135*? I thought you needed higher temps to do this effectively.

    Just curious.

    Normal Vent

    What is a normal vent, if were talking Spiro- vent or the like then yes. If you're talking bulge in the pipe old time purge probably not.
