Navien Boilers
High-efficiency condensing wall-hung boilers for radiant, hydronic, and whole-home space heating.
Navien's NHB-series boilers deliver up to 95%+ efficiency in a compact, wall-hung condensing package — ideal for radiant floors, hydronic baseboards, and homes upgrading from an old cast-iron gas boiler.
About Navien Boilers
A modern Navien boiler is a very different animal from the 40-year-old atmospheric unit in the basement. Wall-hung, sealed-combustion, condensing, and modulating — meaning it puts out only as much heat as the moment needs, with almost every BTU of gas becoming useful heat instead of stack exhaust. For radiant retrofits and hydronic multi-zone systems, Navien is one of our most-installed brands.
