Triple-Flex™ ultra-high efficiency condensing “Flexible Water Tube” boilers have 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 of 99 percent are achievable with lower return water temperatures as found in new building designs. The boilers fire at 3,000 MBtuh input with under 30 ppm NOx levels utilizing a hybrid metal fiber 5:1 turndown burner and Honeywell Sola hydronic safety controls and interface systems. Features include easily replaceable stainless steel flexible tubes and variable-speed combustion air blower. The easy-to-remove access panels make the boiler interior accessible for both service and inspection.
