Navien took the first step into the non-condensing market by introducing its new Navien Premium Non-condensing (NPN) series tankless water heaters during its tankless innovation event at North American headquarters in Irvine, California.
The new NPN is offered in two series, the NPN-U (universal) and NPN-E (exterior), both of which will be available in 160,000, 180,000 and 199,900 Btu/h models for either natural gas or liquid propane (visit Facebook.com/PMmagazine/videos for more).
