Navien took the first step into the non-condensing market by introducing its new Navien Premium Non-condensing (NPN) series tankless water heaters. The new NPN will be offered in two series, the NPN-U (universal) and NPN-E (external), both of which will be available in 160,000 BTU/H, 180,000 BTU/H and 199,900 BTU/H models for either natural gas or liquid propane. Navien utilizes the technology and innovation that helped make the NPE series the number one condensing tankless water heater in North America in its new NPN series, with some new additional features.
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. The NPN-U series are the first and only non-condensing tankless water heaters to offer indoor and outdoor operation within the same unit and include an integrated control panel within the cover of the unit. Both the NPN-U and NPN-E 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 0.81 UEF NPN series include: wi-fi remote control capability with NaviLink, cascade capability with other NPN units, low noise levels for quiet operation, and a sleek, space-saving and lightweight design.
