The Inferno Modular AG series gas-fired hydronic (water) heating plants, 360,000 to 2,400,000 Btuh input and larger, consists of individual, self-contained boiler modules, each of which can operate completely independent of the other units. The AG series is suited for heavy duty space heating, large volume water heating or a combination of space/volume water heating with an external heat exchanger. Maximum efficiency is attained by step-firing only the modules which are required to satisfy the heating demand.
