Bryan’s Triple Flex ultra-high-efficiency condensing boilers feature flexible stainless-steel tubes, minimal thermal efficiency of 90% with 160° F return, 180° supply at maximum input. Efficiencies of 99% are achievable with lower return water temperatures as found in new building designs. Triple-Flex fires at 3,000 MBH input with 30 ppm NOx utilizing a hybrid metal fiber 5:1 turndown burner. Suited to deliver the industry’s highest operating efficiencies of 99% in new buildings designed for condensing boiler conditions and 90%+ efficiency in retrofit applications not designed for condensing boilers.
