Three models - the TF 150, TF 200, and TF 250 - are additions to the Triple-Flex™ (patent pending) ultra-high efficiency condensing flexible water tube boiler. They have inputs from 1,500 to 2,500 MBtuh with less than 30-ppm NOx utilizing a hybrid metal fiber burner. According to the manufacturer, the models offer a guaranteed minimum thermal efficiency of 90 percent in worst-case condensing boiler operating conditions, such as 160°F return water, 180° supply water at 100 percent firing load. Efficiencies up to 99 percent are achievable with lower return water temperatures as found in new building designs. Other features include easily replaceable stainless steel flexible tubes, and a variable-speed combustion air blower. The boilers have easy-to-remove access panels, making the boiler interior accessible for both service and inspection.
