Designed for variable primary flow systems, Fulton’s ENDURA+ firetube condensing heat boilers represent a revolution in firetube condensing boiler technology.
Whereas conventional boiler designs transfer stresses directly onto the most critical components, Fulton’s patent-pending stress reliever completely eliminates these stresses and significantly increases boiler longevity. ENDURA+ provides industry-leading performance without sacrificing durability.
With an ultra-compact footprint, automatic maintenance reminders, and trending data logs, the ENDURA+ is easier to install and service.
