Heat Exchanger

Navien tankless water heaters utilizes dual stainless steel heat exchangers, providing 3.8 to 4.5 times longer life-expectancy and erosion resistance over the copper heat exchangers used in other tankless brands. Navien’s heat exchangers operate with relatively low water temperature, minimizing damage from hard water conditions and maintains efficiency levels. Its always important to have your tankless flushed once every 2 years or so to remove any buildup from within the heat exchangers.

Efficiency

Because of Naviens high efficiency the tankless can be vented in PVC piping.  Basically excess heat is exhausted with all the combustion gasses in conventional tank systems but a Navien uses this to further heat the water. This results in significantly lower exhaust temperatures and allows for the use of PVC exhaust vent piping.
