THE TRIPLE FLEX CONDENSING BOILER is now offered in three new models, the TF 150, the TF 200 and the TF 250, with inputs of 1,500 to 2,500 MBH. They offer a minimum thermal efficiency of 90% in worst-case condensing boiler operating conditions (such as 160ºF return water, 180ºF supply water at 100% firing load). Efficiencies up to 99% are possible with the lower water return temperatures found in new building designs. They ensure low NOx emissions, thanks to a hybrid metal fiber burner.
