Innovations make Navien condensing combi-boilers the best choice for homeowners
Dual stainless steel heat exchangers last longer than copper
Condensing technology reduces energy consumption and greenhouse gas emissions
Optional NaviLink™ Wi-Fi control system gives you access to your Navien systems from anywhere in the world
Protect the environment as you add value
Navien primary condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing tankless heaters 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.
