Endless hot water when you want it.
Navien tankless water heaters deliver a continuous flow of hot water for as
long as you need it. There’s no waiting for a storage tank to warm up.

No “shower shock” effect
Navien NPE-A models have the built-in ComfortFlow® system which eliminates a sudden
blast of cold water during your hot shower, also known as “shower shock” cold water sandwich.
This issue is common on many competitor’s tankless water heaters.

Compact design saves space
The Navien NPE Series sleek, wall-mounted tankless water heaters occupy
80% less space than traditional 50-gallon tank water heaters.
These compact tankless units can also be installed in cabinets or small
closets, unlike bulky tank water heaters.

Credits and rebates
There are a variety of energy efficiency credits and rebates available.

Lower energy bills, easier on the planet

Unlike systems that waste energy to heat large tanks of water, Navien ankless units utilize .98¢ of every $1 to heat your water. Unlike a conventional tank system, it only fires up when hot water is needed allowing great utility savings and a lower impact on the environment. What’s more, Navien tankless heaters reduce CO2 output by ~1,216.8 lbs.**
per year compared to traditional tank type heaters. Navien PE‑Series tankless water heaters are the most efficient according to the EPA Energy Star Directory
