About Navien Water Heaters
Navien water heaters represent cutting-edge condensing technology and exceptional energy efficiency from Korea's largest water heating and boiler manufacturer. Founded in 1978 and entering the North American market in 2006, Navien (Korean for "beautiful warmth") quickly revolutionized the tankless water heater category through innovative engineering and aggressive efficiency targets. The company pioneered the first condensing tankless water heater, achieving efficiency levels previously thought impossible in on-demand systems. Navien's parent company, KD Navien, operates state-of-the-art manufacturing facilities and maintains a strong presence throughout Asia, Europe, and North America. The brand appeals to environmentally conscious consumers, green builders, and homeowners seeking maximum energy savings and endless hot water capabilities.
Navien specializes in condensing tankless water heaters and combi-boilers that deliver both space heating and domestic hot water from a single compact unit. Their NPE series tankless models achieve Uniform Energy Factors up to 0.97, extracting usable heat from combustion gases that conventional units waste through the flue. Dual stainless steel heat exchangers provide exceptional durability and corrosion resistance even in harsh water conditions. Advanced controls maintain precise temperature stability within one degree, preventing the temperature fluctuations common with older tankless designs. Built-in recirculation pumps enable instant hot water delivery throughout the home. The NCB combi-boilers integrate radiant floor heating, baseboard heating, and domestic hot water in an ultra-efficient package. WiFi connectivity allows remote monitoring and control through smartphone apps.
Navien backs its innovative products with industry-leading warranties including 15-year coverage on heat exchangers and comprehensive parts protection that reflects their confidence in product durability. The company has established an extensive network of trained dealers and service technicians through rigorous certification programs that ensure proper installation and service capabilities. Technical support specialists provide assistance with system design, troubleshooting, and optimization. Navien maintains comprehensive online resources including installation manuals, service bulletins, and training videos. Their serial number system uses modern encoding that incorporates production date information, and the units' diagnostic displays provide detailed error codes that facilitate efficient troubleshooting and minimize downtime when service is required.
