Innovations make Navien condensing heating boilers
the best choice for homeowners
The condensing technology in the stainless steel heat exchangers of the NFB-H and NHB boilers saves energy, reduces green house gasses and lasts longer than copper
Space saving design – Both the NFB-H Series and NHB Series boilers have a sleek wall‑hung using
Optional NaviLink™ Wi-Fi control system gives you access to your NHB and NFB-H boiler from anywhere in the world
Low exhaust gas temperatures allows use of PVC, CPVC, ULC S363, PP and SS 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
Turndown ratio up to 15:1 on NHB and 10:1 on NFB-H – 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
Space saving design occupies 80% less space than a traditional floor standing boilers.
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 to reduce energy consumption and CO₂ emissions that keeps exhaust temperatures very low. So low that economical Schedule 40 PVC pipe can be used for venting in almost all applications.
The ultimate
in energy efficiency
Navien condensing combi-boilers are Energy Star certified, providing an AFUE of 95.0%. These extremely efficient and eco-friendly units provide extra energy savings over a traditional floor standing boiler.
