IRVINE, Calif. — Navien, a condensing technology manufacturer, took the first step into the noncondensing market by introducing its Navien Premium Non-condensing (NPN) Series tankless water heaters during its tankless innovation event at their North American headquarters in Irvine, California. The NPN will be offered in two series, the NPN-U (universal) and NPN-E (exterior), both of which will be available in 160,000 Btuh, 180,000 Btuh, and 199,900 Btuh models for either natural gas or liquid propane.

Navien utilizes the NPE Series technology and innovations in its NPN series, with some new, additional features. The NPN Series offers NaviTech™ technology that includes a stainless-steel heat exchanger and an advanced stainless-steel burner with the same low NOx level as the NPE. The NPN-U series offers indoor and outdoor operation within the same unit and includes an integrated control panel within the cover of the unit. Both the NPN-U and NPN-E have recirculation controls 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. For more information, visit
