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.
- Rugged Duplex Stainless Steel Firetube Heat Exchanger
- Designed for Variable Primary Flow
- Low NOx (<20ppm) Emissions
- Compact Footprint – Fits Through a Standard Doorway
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.
