Navien’s new NPN (premium non-condensing) series of tankless water heaters is offered in the NPN-U (universal) and NPN-E (exterior) options, both of which will be available in 160,000 Btu/h, and 199,900 Btu/h models for either natural gas or liquid propane. The 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. Also offers indoor and outdoor operation within the same unit and includes an integrated control panel within the unit cover. Both have recirculation control built into the circuit boards and are designed with a pin-to-pin matching configuration for easy retrofit installations.
