An open hydronic heating system will always pick up air. There are tiny bubbles that circulate with the water, and rise to the top of the radiators.

The other bad feature of a system such as this is the air bubbles (oxygen) carried through the system greatly worsens rust damage to the pipe fittings and boiler.

A typical hydronic system has an air separator to vent all air that accumulates in a raised chamber in the air separator, and the system is kept at a constant 12 PSI by a bladder tank that keeps the water and the air cushion separated.

Is your boiler a factory product that is capable of being used in a 12 PSI system?

If it is an approved unit, there will be an ASME rating plate on it listing approved pressure, which on an approved unit will be well over 12 PSI.

To sum this up... If your boiler is capable of use at 12 PSI, and you set up a closed sytem with an air separator and air cushion tank, after a day or two of the air separator venting air, the system will settle down, and the piping and radiators will be quiet of bubbling and gurgling sounds. You might have to bleed the radiators at the start of each heating season, but that should be about it.
