Navien Condensing Tankless Water Heater (NPE-S2)
The Navien NPE-S2 series of condensing tankless water heaters comes in various models, depending on your water heating needs. Common with all tankless water heaters, the unit provides a continuous flow of hot water and offers savings on energy and fuel. Because Navien heating boilers use condensing technology, they retain and recycle some of the heat and exhaust gasses that would be lost in more conventional units, which further improves their energy efficiency. This series has an efficiency rating of up to 0.96 UEF.
Each unit in the series is lightweight, compact, and easy to install. Plus, the EZNav™ control panel provides easy-to-understand text and icons to display things like temperature and water flow, which makes it easy to troubleshoot any issues that may arise.
The NPE-S2 series is available in four models with different flow rates:
NPE-150S2 (120K BTU, up to 6.8 gallons/minute)
NPE-180S2 (150K BTU, up to 8.4 gallons/minute)
NPE-210S2 (180K BTU, up to 10.1 gallons/minute)
NPE-240S2 (199K BTU, up to 11.2 gallons/minute)
