The Navien NPE-2 series brings the biggest update to condensing tankless water heaters since the NPE series changed the landscape of the industry in 2012. The new features found in the NPE-A2 and NPE-S2 series include a turndown ratio up to 15:1, an upgraded advanced multi-line control panel in English for easy set up, and increased 2-inch PVC venting length. The NPE-2 will continue to offer the high-efficiency features that made the NPE the number-one selling condensing tankless water heater, such as dual stainless steel heat exchangers, 1/2-inch gas pipe capability up to 24 feet, cascade and common vent capability, industry-leading efficiency up to 0.97 UEF, and the patented ComfortFlow recirculation system with built-in pump and buffer tank on the NPE-A2.
