Navien has introduced three new products. The NPN series non-condensing tankless water heaters, NPE-2 series condensing tankless water heaters and NCB-H series condensing combi-boilers provide technological advancements within each series.
Available in the NPN-Universal series (indoor or outdoor with vent cap) and NPN-Exterior series (outdoor only), Navien utilizes the technology and innovation that helped make the NPE series popular in their new non-condensing NPN series, with some new additional features. The NPN series is a non-condensing tankless series that offers NaviTech technology, including a stainless-steel heat exchanger and a stainless-steel burner with the same NOx level as the NPE. Both the NPN-U and NPN-E have built-in recirculation control, air pressure sensor, water adjustment valve and mixing valve, and are designed with a pin-to-pin matching configuration for retrofit installation ease.
The NPE-2 series brings an update to condensing tankless water heaters. The features found in the NPE-A2 and NPE-S2 series include a turndown ratio up to 15:1, an upgraded multi-line control panel in plain English for set up ease, and increased 2-inch PVC venting length. The NPE-2 will continue to offer high-efficiency features such as dual stainless steel heat exchangers; half-inch gas pipe capability up to 24 feet; cascade and common vent capability; efficiency up to 0.97 UEF and the patented ComfortFlow recirculation system with built-in pump and buffer tank on the NPE-A2.
NCB-H (high output) series condensing combi-boilers are packed with upgrades to the NCB-E series, including BTU output on DHW; 15:1 turndown ratio; a dynamic BTU lineup with added models; improved DHW performance; a new DHW module with flow control; enhanced controls with multi-line text display; increased 2-inch PVC venting length; serviceability ease with upfront 3-way valve and built-in controls for up to 3 zones.
