About the brand
Why Navien?
Installed and serviced locally by Eagle Pipe Heating & Air — your licensed plumbing team in Poulsbo, WA.
Navien's premium efficiency condensing technology has revolutionized residential water heating. Unlike traditional tank water heaters that continuously heat and reheat a stored volume of water 24 hours a day, Navien tankless systems activate only when you turn on a faucet—heating water instantly and delivering it for as long as you need it. The result is an endless supply of hot water, significantly lower energy bills, and a compact wall-mounted unit that frees up valuable floor space in your home.
As the #1 selling condensing gas tankless water heater manufacturer in North America, Navien has earned the trust of homeowners and professionals alike. Their NPE-2 series achieves an ultra-high Uniform Energy Factor (UEF) of up to 0.96, making them up to 34% more efficient than conventional storage tank water heaters. The exclusive ComfortFlow technology—featuring a built-in recirculation pump and buffer tank—eliminates the "cold water sandwich" effect, ensuring hot water arrives at your fixture faster than ever.
Eagle Pipe Heating & Air's licensed plumbers are trained and experienced in Navien tankless installations, including proper gas line sizing, venting configuration, and water flow optimization. We ensure every installation meets local building codes and Navien's warranty requirements.

Our installers did wonderful work putting in our new HVAC and it was a difficult job. Eagle's estimator was the only one to figure out how our job could be done without moving a major pipe, thus involving more time plus a plumber. Her out-of-the-box thinking saved us about $6,000 compared to the other two companies, but it did make extra work for our installers. However, they worked constantly, got the job done in a day & cleaned up beautifully. We are very grateful.

Adisen was a breath of fresh air. He was very polite, pleasant, presentable and on time. He stayed and checked different things with our water booster pump which wanted to run all the time, until he found the leak which didn't take long. Talking with the nice people in the office was very pleasant. I highly recommend him along with Eagle Pipe Heating and Air. I shall definitely use their service should I need it again.

Navien questions
Frequently asked questions
How long does a Navien tankless water heater last?
With proper annual maintenance, Navien tankless water heaters can last up to 20 years—nearly double the lifespan of a conventional tank water heater.
Will a tankless water heater work for my whole house?
Yes. Navien's condensing models are designed to supply multiple fixtures simultaneously. Our plumbers use Navien's NaviSizer tool to properly size the unit for your household's peak demand.
Can I install a Navien tankless water heater myself?
No. Navien requires installation by a licensed contractor to maintain warranty coverage. Installation involves gas line sizing, proper venting, and electrical connections that require professional expertise. Eagle Pipe's licensed plumbers handle the entire process.
What is the "cold water sandwich" and how does Navien solve it?
A cold water sandwich is a brief burst of cold water between hot water uses, common with basic tankless units. Navien's exclusive ComfortFlow technology uses a built-in buffer tank and recirculation pump to eliminate this issue entirely.
