This Tankless Water Heater Series Resists Corrosion and Recovers Heat

The NPE-2 Series of condensing tankless water heaters by Navien make it easier than ever to go tankless. Dual stainless steel heat exchangers help extend the life of the unit by resisting corrosion, and the condensing exchangers also recover extra heat that would be lost in non-condensing units. Lower CO2 emissions and low exhaust temperatures allow for less expensive venting materials, such as schedule 40 PVC.

Advanced models feature a buffer tank, a recirculation pump and fine-tuned controls that resolve the cold-water sandwich effect. The EZNav control panel uses simple text and icons to make setup, operation status and troubleshooting easy and fast. Up to 32 units can be cascaded together to provide larger flow rates for any commercial or multi-family application.
