Navien Premium Efficiency Tankless Water Heaters

A tankless water heater is a type of water heater that doesn’t use a storage tank to heat water. Instead, hot water is produced only when you need it. Tankless water heaters are smaller and more efficient than traditional water heaters.

Navien Premium Efficiency condensing tankless water heaters are the #1 selling high efficiency condensing tankless water heaters in North America. The NPE-2 series offers ultra-high efficiency up to 0.96 UEF to keep your utility bills low, endless hot water, and exclusive ComfortFlow® technology with a built-in recirculation pump and buffer tank.
