Gas-fired condensing boiler
December 1, 2012
Viessmann’s Vitocrossal 200, CM2 gas-fired condensing boiler offers thermal efficiency up to 97%. Its fully modulating premix cylinder burner operates with low inlet gas pressure of only 4”, while the large water content extends burner run time and reduces cycling. With fuel flexibility, multiple venting options and inputs from 663 to 1,112 MBH (single)/663 to 4,448 MBH (four-boiler cascade), the Vitocrossal 200, CM2 is ideal for large residential and commercial applications.
