Engineered for Operations Where Capacity, Performance, and Serviceability Matter

The Fulton Endura+ ultra-high efficiency firetube condensing boiler is available in sizes 8, 10, and 12 million BTU, giving you more capacity for demanding commercial and industrial heating projects. Built for variable primary flow systems, Endura+ delivers the efficiency, durability, and serviceability Fulton is known for, just at a larger scale.

The Endura+ line now spans 2.5 to 12 million BTU, so you can match capacity to project size without sacrificing efficiency or footprint. These larger sizes are ideal for healthcare, municipal, government, education, multifamily, hospitality, and large mixed-use facilities where high output and long-term reliability matter most.

Why Choose the Endura+?

  • Ultra-high efficiency condensing performance:
    Achieve AHRI thermal efficiencies up to 96%+, to reduce fuel consumption and operating costs.
  • High turndown for precise load matching:
    The 8, 10, and 12 MMBTU models offer 20:1, 25:1, and 30:1 turndown ratios, enabling smooth modulation to match changing loads and improve part load efficiency.
  • Reduced thermal stress:
    Redistributes thermal stresses away from critical components, significantly increasing boiler life and reducing long-term maintenance.
  • Compact footprint with easy service access:
    Even at these larger capacities, Endura+ maintains a compact footprint and simplified access, with panels that detach quickly and knockdown capable construction for retrofit applications.

Built for Demanding Applications

Featuring a durable stainless steel firetube heat exchanger, the 8, 10, and 12 MMBTU Endura+ models are engineered for high-demand facilities where uptime, thermal performance, and ease of maintenance are critical. Typical applications include:

  • Healthcare campuses and hospitals
  • Municipal and government buildings
  • University and education districts
  • Large multifamily, hospitality, and mixed-use complexes

With the 8, 10, and 12 MMBTU Endura+ models available, you can specify a boiler that grows with your facility’s capacity needs while maintaining the efficiency you require.
