Navien NPE-S2 Tankless

High-Efficiency Condensing Tankless

The Navien NPE-S2 delivers endless hot water with up to 0.96 UEF efficiency in a compact wall-mounted design. As a condensing tankless water heater, it captures additional heat from exhaust gases that non-condensing units waste — resulting in higher efficiency, lower operating costs, and PVC venting for simpler installation.

Tankless Advantages

Tankless water heaters only heat water when you need it, eliminating the standby energy loss of keeping 40-50 gallons hot 24/7. The Navien NPE-S2 provides unlimited hot water regardless of demand, takes up minimal wall space, lasts 20+ years (vs 8-12 for tank heaters), and qualifies for significant utility rebates.
