Product Overview

Designed for variable primary flow systems, Fulton’s ENDURA+ firetube condensing 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.
