    Fix the leak in the system, or replace the boiler.

    Fix the leaks , it could be the return pipe.(condensation leaks ) If you do not see any , it could be under the floor . Steam leaks , normally leaky vents , radiator valve packings or loose unions ...
    I have enough experience to know , that I dont know it all

    How often does it need refilling?
    Hopefully the LWCO stops the burner when the water drops low enough.

    Look for steam coming out of the chimney... :'(

    Or with the boiler off and fairly cool, overfill the boiler to the header pipes, let sit for at least an hour and look for water on the floor. :'(:'(

    Do you have return pipes under the floor?
