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.

All the hot water you need, for as long as you need it.

Navien offers models of tankless water heaters that use either condensing or non-condensing technology.

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.

Non-Condensing Tankless Water Heaters

Navien premium non-condensing tankless water heaters deliver a continuous flow of hot water for as long as you need it. No waiting for a tank to reheat more water, wasting time and energy.
