ClearFire - Model CE (CFC-E) -Fully Assembled, High-Mass Firetube Condensing Boiler
The ClearFire®-CE (CFC-E) is a fully assembled, high-mass firetube condensing boiler with a large-water-volume pressure vessel. The high-mass design equates to a low pressure drop, reducing pumping energy with no minimum flow requirements. The pressure vessel is also thermal shock proof, capable of high-delta-T system designs to maximize condensing and reduce flow rates. The highly effective fireside heating surface with industry leading AluFer® tubes leads to superior efficiencies in all operating conditions. The modulating, premix burner control automatically adjusts the air/gas mixture for maximum burner efficiency. The linkageless burner provides fully modulating turndown without the use of complex air/fuel mixing valves. The dual-return connections have the ability to increase condensing in the boiler and raise efficiencies by 6%+ more than a single-return boiler.
