Navien has added 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. 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.
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 space-saving, lightweight design.
