CHR-FLUE™ System installed for multiple Boiler Exhaust to replace stack.

• Completed Fall 2003
• CHR System installed for multiple Boiler Exhaust (x3) to both replace common stack and reduce fuel consumption and air pollutant emissions
• Peak heat recovery rate: 5.5 mmBTU/h, at peak Hot Water Boilers NG Input = 30.5 mmBTU/h
• Reduction of boiler fuel (natural gas) consumption by 18%
• Annual savings of over $110,000 (2003), which today is valued at $220,000/Year
• Expected Simple Pay Back <4.5 years
• Reduction of air pollutants and visible plume
• Over 25% reduction of CO₂
