Product Overview

Designed for variable flow primary hydronic applications, the ENDURA™ condensing boiler is built to last using only the best materials and components. Features include simple installation, low emissions burner performance, and a rugged-construction pressure vessel.

ENDURA boilers provide simple accessibility for commissioning and maintenance with latched cabinet panels and hand-wired electrical panels with terminal blocks. Key components are located strategically to facilitate a one-inch side clearance between multiple boilers.

Better by Design

ENDURA boilers are built on a proven heat exchanger platform engineered and manufactured by Fulton. The design features rugged welded construction and a high-mass pressure vessel.

  • Fully Duplex Stainless Steel heat exchanger has 19% greater strength and a 23% reduction in thermal expansion compared to conventional 316L used by the competition.
  • Fully wetted three-pass firetube design operates with lower stresses and therefore greater durability.
  • Corrugated flue pipes increase surface area and turbulence, enhancing fuel-saving efficiencies.
  • The high water volume counter-flow design is exceptionally tolerant of varying and sometimes unpredictable system flow rates; a zero flow condition will not harm the boiler.
