The new Genesis® high-efficiency gas boiler line includes six new, high-output hot water supply models and six new hydronic heating models, all with ranges from 1 to 2.5 MMBtu. Key features of the line include 84% thermal efficiency, Dia-Scan II staged firing, a stackable design, and a double-row, self-baffling heat exchanger. The models also feature a combustion system which consists of precise amounts of gas and air premixed through pre-jet orifices and forced by fan propulsion through stainless steel burners that are designed to provide complete and clean combustion, according to the manufacturer.
