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 87.1%, CFR is the highest efficiency Category I boiler available today. 2000 MBH input model has been added to the 1500 MBH and 3000 MBH product line. CFR’s advanced design and technology maintain dry flue gas while exceeding efficiency standards, thereby enabling it to safely use existing Category I/Type B venting.
This eliminates the need to update expensive piping and venting typically required for condensing operation, and provides significant savings in installation time and money.
Reasons to Choose CFR
Additionally, CFR comes with an industry-unique warranty against condensate corrosion, providing added peace of mind and improving the lifetime value of the boiler.
