Navien NFB High-Performance Condensing Heating Boilers

NFB heating boilersNavien is one of the leading providers of innovative high-performance and high-efficiency boilers in North America. Their advanced stainless steel NFB heating boilers boast superior space and energy efficiency that can significantly reduce your monthly operational costs without compromising on service or performance quality.

Using the most cutting-edge automated laser welding technology, the engineering masterminds at Navien have designed and manufactured a state-of-the-art compact heat exchanger that minimizes energy consumption and maximizes ease of use.

Navien NFB High-Performance Condensing Heating Boiler

In addition to being ASME-certified and “H”-stamped, the advanced-patented stainless steel heat exchanger in Navien heating boilers is designed to reduce high stress point weld failures. What differentiates Navien NFB High Performance boilers from others on the market?

  • A low-profile burner design that’s easy to remove or adjust for better access and serviceability as needed
  • NFB’s innovative heat exchanger design that eliminates the need for additional insulation and allows water to fill the entire heat exchanger
  • One-piece combustion chamber to prevent corrosion on welding points
  • EPP insulation on the outside of the heat exchanger to increase system efficiency by reducing heat loss
  • Patented turbulators inside the tubes that reinforce structural integrity and maximize the heat transfer rate to improve efficiency by creating a cyclone or vacuum effect of flue gases
  • New heat exchanger diaphragm design that’s designed to boost overall performance and optimize the flow of water through the system
