About the Free Flex (FF) Series

Bryan's Free Flex page describes the line as 'Bryan Boilers' newest Ultra High Efficiency condensing boiler', 'built with Bryan's exclusive flexible watertube heat exchanger, but now in a stainless steel design with a competitive installed footprint'. The page prints '1000 to 3000 MBH input, AHRI Certified at 95% Thermal Efficiency, fully field repairable, a Lifetime Thermal Shock Warranty, and Variable-Primary or Primary/Secondary piping'.

The published submittal sheets print per-model ratings: input low and high fire, output high fire, boiler horsepower, thermal and combustion efficiency, water volume, fuel, firing mode, turndown, NOx note, minimum and maximum flow rates with head loss, shipping weight, dimensions, water/vent/air/gas connections and electrical requirements. Boilers.ca documents four sizes (1000, 1500, 2000, 3000) from those official submittals.

The FF uses an ASME stainless steel flexible water tube heat exchanger with field-replaceable tubes, MAWP 160 PSIG and 210°F maximum temperature, the Concert control and a ten-year pressure vessel warranty plus lifetime thermal shock warranty. Submittals for 3500–6000 MBH are also published on the product page. No official Canadian-sales statement was found.
