The ENDURA is Fulton's condensing duplex-stainless firetube boiler in four sizes — EDR-750, EDR-1000, EDR-1500 and EDR-2000 (750,000–2,000,000 BTU/hr) — with a fully-wetted 3-pass design, variable primary flow and low NOx under 20 ppm.
Series facts
Fulton presents the ENDURA as an 'ultra-high efficiency condensing boiler' with a duplex-stainless fully-wetted 3-pass firetube design and variable primary flow. The page prints a size range of 750,000–2,000,000 BTU/hr with the model inventory EDR-750, EDR-1000, EDR-1500 and EDR-2000.
Fulton states the ENDURA's stainless firetube material offers greater strength than conventional 316L (page copy: '19% greater strength') and the line runs low NOx (under 20 ppm). Fuels are natural gas or propane. The page's Specs & Dimensions tab carries an AHRI Thermal Efficiency table whose per-model values are not re-typed in Boilers.ca's research file, so no structured percentage is printed here.
The page's documents tab publishes the brochure, I&O and specification as public PDFs; the brochure is linked from this hub. Fulton's rep finder lists Canada, but no explicit Canadian product statement was found.
