AERCO, a Watts brand, announces the expansion of its groundbreaking CFR condensing boiler line with the addition of a new 2000 MBH model. CFR is the world’s first stainless steel condensing boiler approved for Category I venting, redefining retrofit possibilities for engineers and facility managers. Now, the CFR boiler is available in more sizing options with 1500 MBH, 2000 MBH, and 3000 MBH units. This milestone follows the recent recognition at AHR Expo 2025, where CFR won the AHR Innovation Award in the Heating category, validating its industry-first capability to reuse existing Category I / Type B venting while delivering high-efficiency performance.
