MOST EFFICIENT STEAM BOILER TYPE

Just doing some research.
For Natural Gas, is it better to get an atmospheric boiler or an oil boiler with a power burner?
I heard oil boilers converted to gas are less efficient, but can be more efficient with the tuneability of the power burner.
Opinions and thoughts are welcome.
Thanks in advance. 😊

    We like to use wet-base boilers that are usually sold with oil burners and put gas burners in them. The difference in thermal efficiency is up to 6%. Here's a thread with a video of one- this one's a Slant/Fin Intrepid:

    Agreed. Having a wet base boiler with the flame (almost) totally enclosed by water makes sense.

    What does "wet base" mean? (I'm still learning)

    It means the flame is almost completely surrounded by cast-iron that has water on the other side. The usual atmospheric gas boiler has the flame completely below the cast-iron, which results in loss of heat from the boiler's base.
