Navien Inc. introduces a new 120,000 BTU/h model to the NPN non-condensing tankless water heater lineup. The NPN-120E is the fourth model introduction to the NPN-E (exterior) series, and just like the other three models in the series (NPN-160E, NPN-180E and NPN-199E), the new size is offered in separate natural gas and liquid propane configurations for outdoor-only operation. NPN-120E provides 4.2 GPM at 45 F temperature rise and stays in-line with the rest of the NPN series at 0.81 UEF.
The NPN series is the first and only non-condensing tankless series to offer NaviTech technology that includes a stainless-steel heat exchanger and an advanced stainless-steel burner with the same very low NOx level as the NPE condensing tankless water heaters. NPN-E units have recirculation control built into their circuit boards and are designed with a pin-to-pin matching configuration for easy retrofit installations.
Additional features of the NPN series include: wi-fi remote control capability with NaviLink, low noise levels for quiet operation, and a sleek, space-saving and lightweight design.
