How the Boiler Operates
Condensing technology intelligently delivers hydronic heating while maximizing efficiency. Outlined below are the features of the system
and how they operate:
Stainless Steel Heat Exchanger - The highly efficient 316L stainless steel fire tube heat exchanger with internal aluminum is designed
to extract all available heat from the combustion process and pass it into heat transfer fluid. The stainless steel construction provides
protection for longer service life. The heat exchanger offers greater water content, providing lower system pressure and greater overall
system efficiency.
10 to 1 Modulating Combustion System - The combustion system is specially designed to provide very high turn down. This
combustion system will modulate the burner output to very low levels to match the system demand and achieve better overall control of
the heating system for maximum efficiency and reliability.
