Winner of the 2025 AHR Expo Innovation Award in the heating category, CFR is a revolutionary best-in-class, drop-in replacement boiler that easily updates non-condensing boiler plants with a high-efficiency alternative. With a thermal efficiency up to 87.6%, CFR is the highest-efficiency Category I boiler available now.
CFR’s advanced design and technology maintains dry flue gas while exceeding efficiency standards, thereby enabling it to safely use existing Category I/Type B venting.
Lifetime value of the boiler
CFR comes with an industry-unique proof against condensate decay, providing added peace of mind
This eliminates the need to update expensive piping and venting typically required for condensing operation, and provides significant savings in installation time and money.
Additionally, CFR comes with an industry-unique warranty against condensate corrosion providing added peace of mind and improving the lifetime value of the boiler. Available in 1500 MBH and 3000 MBH.
