What actually separates them

Bryan's submittals print the Free Flex 2000 at 400,000–1,999,000 BTU/hr input and 1,899,000 BTU/hr output, and the Free Flex 3000 at 600,000–3,000,000 BTU/hr input and 2,820,000 BTU/hr output, both at 95% thermal and 94% combustion efficiency on natural gas.

The vent and air intake step from 8" to 10", length grows from 80" to 93", water volume from 27 to 39 gallons and shipping weight from 2,020 to 2,500 lb. Width and height are unchanged at 35" and 75".

Flow rises from 45–190 gpm to 67–285 gpm across the ΔT span, and boiler horsepower from 57 to 84. Both carry the same ASME Section IV ratings and warranty package, and both are documented as fully field repairable with replaceable stainless tubes.
