Cleaver-Brooks is First to Achieve AHRI Certification for 8,000 MBTU/hr Hydronic Condensing Heating Boiler

Thomasville, GA:  May 10, 2016

Cleaver-Brooks announces that it has earned AHRI certification for its first-in-class ClearFire®-LC (CFLC) 8,000 MBTU/hr hydronic condensing boiler. Cleaver-Brooks is the first manufacturer in the industry to achieve AHRI certification for a hydronic condensing heating boiler of this capacity. The CFLC large-capacity condensing model earned a combustion efficiency rating of 94.0% and a thermal efficiency rating of 94.4% in independent, third-party tests certified by AHRI.

Cleaver-Brooks also earned AHRI certification for its CFLC 6,000 MBTU/hr hydronic condensing boiler. This model earned a combustion efficiency rating of 94.0% and a thermal efficiency rating of 95.0%. 

Products in the CFLC line feature an integrated premix gas burner and linkageless control that work together to provide full modulation, high turndown, and ultra-low emissions to 9 ppm NOx. CFLC boilers are engineered in a high mass firetube design, utilizing extended heating surface AluFer® tubes and EX spiral tubes in a true counter-flow arrangement, enabling them to achieve up to 98% efficiency. 

The CFLC product line includes models that range in size from 4,000 to 12,000 MBTU/hr. Cleaver-Brooks also manufactures a line of smaller-size premium efficiency hydronic condensing boilers that have earned AHRI certification. Boilers in the company’s ClearFire-C line are available from 500 to 3,300 MBTU/hr. 

The Air Conditioning, Heating and Refrigeration Institute (AHRI) administers the AHRI Certification Programs that test and certify the performance of HVACR and water heating equipment. Its industry-respected approach to product certification requires the performance of equipment in the program to be independently measured and verified, allowing for fair product comparisons.
