NPN-180E-LP Navien Tankless Water Heater

The NPN series is the first and only non-condensing outdoor gas tankless water heater to offer a stainless steel heat exchanger which provides very low NOx comparable to our NPE series.

All NPN-E units include built-in recirculation control and software, and a water adjustment valve (WAV) and mixing valve to stabilize temperature during flow changes. The built-in air pressure sensor (APS) monitors and maintains air/gas pressure ratio during operation and ensures consistent hot water output during partial air blockage.
