  • Ideal for replacements or new construction

Navien boilers save substantial space over old floor standing units

Before
After

Innovations make Navien condensing heating boilers the best choice for homeowners

  • The condensing technology in the stainless steel heat exchangers of the NFB and NHB boilers saves energy, reduces green house gasses and lasts longer than copper

  • Space saving design – Both the NHB Series and NFB Series boilers have a sleek wall‑hung using

  • Optional NaviLink™ Wi-Fi control system gives you access to your NFB and NHB boiler from anywhere in the world

  • Low exhaust gas temperatures allow use of PVC, CPVC, polypropylene (rigid and flexible) and stainless steel venting reducing installation time and costs. System can use 2" venting for up to 60', or up to 150' with 3" venting.

  • Very low noise levels – Installations in or near media rooms, recreation rooms or any living areas of the house are possible with these quiet running boilers

  • Turn down ratio up to 15:1 on NHB and 10:1 on NFB – The sophisticated gas flow control system provides a high turn down ratio which reduces energy waste and excessive boiler cycling while also enhancing temperature control for DHW

Protect the environment as
you add value

 

Navien primary condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing boilers. The result is reduction in energy consumption, lower CO₂ emissions and very low exhaust temperatures allowing use of less expensive venting materials such as Schedule 40 PVC.

The ultimate
in energy efficiency

 

Navien condensing boiler technology provides 95.0% AFUE, recognized by Energy Star as Most Efficient. These extremely efficient and eco-friendly units provide extra energy savings over a traditional floor standing boiler.
