NPN-E Models

Navien gas outdoor tankless water heaters can be cascaded to meet high-volume hot water demand. 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.
