This video is of the primary combustion chamber of the modified outdoor boiler. Note that the firebrick sides have no soot, this system runs so hot that all the soot burns off. You will see a bit of smoke, this smoke is consumed in the secondary combustion area, which gives this unit a clean burn.
Net delivered efficiency went from 22% to over 48%

Was this a gain or loss in total efficiency?
Better combustion Vs less heat transfer area...
