About Navien
Navien dominates the tankless water heater and wall-hung boiler market in North America - leading market share in both categories since entering the U.S. in 2006. The company is backed by KD Navien (KyungDong Navien), a Korean manufacturer with 40+ years of heating technology experience. Growth has been explosive: Navien went from unknown to category leader in under two decades.
Condensing technology is Navien's specialty. Their tankless water heaters and combi-boilers extract heat from exhaust gases that conventional units waste, achieving efficiency levels that qualify for federal tax credits. The company holds more technology patents in its category than competitors, and operates training centers in California, New Jersey, and Ontario.
Navien has recently expanded beyond water heating into HVAC with the NPF hydro-furnace and heat pump water heaters. For homeowners focused on water heating specifically - tankless, combi-boilers, or high-efficiency tank units - Navien is the specialist brand that contractors increasingly recommend.
