The Evolution Condensing Boiler (EVCA) was developed to address the needs of today's energy efficient marketplace. The EVCA takes all the proven features of the Evolution design and makes them even better. Adding a secondary stainless steel heat exchanger and superior control technology allows the Condensing Evolution to achieve the highest efficiencies possible in a hot water boiler product.

HIGHLIGHTS

• Efficiencies up to 97% (BTS-2000 Certified)

• Ultra-low NOx levels below 9 ppm; meets or exceeds the most stringent emission requirements in the United States

• CO less than 50 ppm
