The in-house-designed and -manufactured heat exchanger is form-pressed and robotic-laser-welded to minimize the number of weak points that could be prone to thermal stress and corrosion.

This Wi-Fi remote control is designed to support remote access for all Navien tankless water heaters (NPE Series), combi-boilers (NCB-E Series), and gas condensing boilers (NHB Series) through the NaviLink Wi-Fi control and mobile app.

A total of 19 volunteers from Navien met with Habitat for Humanity on March 18 and spent the day at a site that had recently been re-opened. 

The NCB-E is part of an NCB Series that, as one unit, is capable of providing a whole-house heating system while also providing the domestic hot water output of a stand-alone, tankless water heater. 

The Navien Heating Boiler (NHB) Series is available in four wall-hung sizes — NHB-55, NHB-80, NHB 110, and NHB-150, with turn-down ratios, respectively, of 7:1, 10:1, 11:1, and 15:1. 

The NCB Series combi-boilers are condensing combination boilers capable of delivering plentiful hydronic heat and unlimited domestic hot water for large homes.
