Is Navien a Good Tankless Water Heater?
Navien is a solid choice when it comes to tankless water heaters. Their units are manufacturered by a company that takes pride in quality, design, and user friendliness. In fact, there’s no shortage of satisfied customers!
If you do decide to buy a Navien tankless, we don’t think you’ll be disappointed with your purchase at all. And with a wide range of models and features to choose between, you’ll be able to find the right heater to meet your household needs.
The Tankless Trend
In recent years tankless water heaters have gained in popularity. Many homeowners have found that going tankless has many advantages over the more conventional tank-style water heaters.
Tankless systems are compact, versatile, eco-friendly, and far more economical to operate than their tank-style cousins. Without the need to store and maintain 50-gallons of water at a temperature of 120°, the majority of the energy a tankless system uses can go directly into heating water.
With today’s demand for connectivity, tankless manufacturers have answered the call and designed models that can be remotely controlled even while you’re on vacation!
Navien Review
Many people haven’t heard of Navien and to be fair, the company is a relative newcomer to the tankless water heater industry. But don’t let that fool you, they’ve built quite a reputation and can compete head-to-head against big players like Rinnai and Rheem.
Today, Navien is headquartered in Irvine, California, but they were founded in 1978 in South Korea and were known as KyungDong Navien (KD Navien). Although the products are still manufactured in South Korea, the company operates training centers in New Jersey, Ontario, and California.
Although, better known in Canada, Navien’s US presence is growing. And for homeowners who are motivated to support “Green” companies, Navien was honored as an eco-leader in 2018 by Green Builder Magazine.
Navien Tankless Water Heater Recall
In 2018 Navien needed to recall 3,400 tankless water heaters because of a risk of carbon monoxide poisoning. The Consumer Product Safety Commission announced the recall and it involved two condensing models, the NPE-180A and the NPE-180S and a condensing combination boiler, the NCB-180E.
The recall was the result of a kit used to convert the units from natural gas to propane and the possibility that it could cause unsafe levels of carbon monoxide. Navien offered owners of these models a free replacement conversion kit.

Navien Tankless Water Heater Product Line
Choosing a tankless water heater can be a confusing process, but we recommend first deciding if you want a condensing or a non-condensing system. The differences between the two are not difficult to understand, but they are very important.
Condensing tankless water heaters have always been a part of Navien’s model line-up, but more recently they’ve added a non-condensing series.
Navien’s NPE-A Series and the NPE-S Series make up the condensing models. And the NPN-U and NPN-E series are part of the non-condensing line-up.
Condensing vs Non-Condensing
The main difference between condensing and non-condensing is how they vent (or don’t vent) the condensation produced during the water heating process.
In both cases, the intense temperature needed to instantly heat your home’s water, as it passes through the tankless water heater, creates steam very quickly.
When the steam cools, it condenses back into water. Only now, as a result of the heating process, the “waste” water is highly acidic and can easily corrode parts, pieces and pipes.
A non-condensing tankless water heater handles that by venting the hot gases outside, where they can cool outside of the unit. With gases as hot as 300° F they must be vented through special, non-corrosive venting materials that can withstand the heat.
And since the internal parts of a non-condensing tankless water heater don’t need to withstand the corrosive wastewater, the internal parts can be less expensive.
On the other hand, condensing tankless water heaters extract the additional heat from the exhaust gases through various means within the unit itself. Because of this, they exhaust cooler gases, around 100° F., and the acidic condensation water is neutralized through filtration or dilution before it’s drained outside.
Since the exhaust gases are much cooler, they can be collected inside the unit and less expensive venting material can be used. However, the internal parts of condensing units tend to be pricier because they need to withstand the corrosive wastewater.
Non-Condensing vs Condensing Tankless Water Heaters
There are some important and fundamental differences to consider when choosing between a non-condensing and condensing tankless water heater:
Non-Condensing Water Heaters
- Efficiency:Typically 80% or higher
- Venting: Requires more expensive venting
- Initial Cost: Typically the tankless unit is less expensive, but installation is more expensive
- Operating Cost: Since the unit’s efficiency is lower, it’ll cost more to operate than a condensing tankless
- Size: Frequently non-condensing units are slightly smaller than condensing tankless systems
Condensing Water Heaters
- Efficiency:Typically 98% or higher
- Venting: Less expensive PVC venting
- Initial Cost: Typically the tankless unit is more expensive, but installation is less expensive
- Operating Cost: Since the unit’s efficiency is higher, it’ll cost less to operate than a non-condensing tankless
- Size: Frequently condensing units are slightly larger than non-condensing tankless systems

- All Models above support Both Natural Gas and Propane.
- EF/UEF: Water heater efficiency is listed as EF (Energy Factor) or UEF (Uniform Energy Factor). EF is an outdated measure and is typically 2-3 percent higher than the UEF, which was implemented in 2017 by the US Department of Energy to produce more consistent ratings across the industry.
- Energy Star: All Navien tankless units are Energy Star compliant.
- Low-NOx: All Navien models meet standards where reduced noxious emissions are required.
- Residential Warranties: The warranties listed in the table are for the heat exchangers and apply to controlled circulation via an internal pump (Advanced models) or when an external pump is used (optional with Standard models). When uncontrolled/constant circulation is used, the heat exchanger warranty is 5 years. All other parts are covered by a 5-year warranty. Labor is covered for 1 year.
Navien Water Heater Features Analysis
These are premium tankless water heaters with impressive features.
All models have dual stainless steel heat exchangers to combat potential corrosion from their condensing performance. To learn more about condensing heaters and their pros and cons when compared with non-condensing, less efficient models, see that section of our Tankless Water Heater buying guide.
- NPE-Advanced models include a recirculation pump and buffer tank, technology called ComfortFlow. It includes a timer, so that the pump isn’t recirculating and reheating water when there’s no demand. The system maintains a small amount of heated water in the tankless unit and pipe leading to designated faucets/outlets. This reduces time and wasted water when waiting for hot water. Keep in mind, though, that heating and recirculating water uses additional energy. It’s a trade off between paying for metered water that’s wasted and paying for gas to fire the unit.
- Navien’s NaviLink is an add-on component for all models that enables WiFi for remote monitoring and control of the water heater. The WiFi control costs $200-$225 from various sellers. Brands like Rheem and Rinnai make some models with built-in WiFi.
- All Navien models offer cascading technology. This means up to 16 units can be linked together, 8 when using a common vent, to serve large homes and commercial applications where a large volume of hot water is in high demand.
- The Navien HotButton is an optional accessory that mounts remotely, near a bathroom for example. The button activates internal recirculation from the unit to a faucet such as a shower using a return line, so hot water is instantly available. The HotButton kit costs about $80. Expect installation to be $150-$300.
- Navien Advanced Series units offer space heating with the H2Air Kit option. Hot water is circulated to a radiator-like heat exchange located in a furnace or air handler. The unit’s blower pulls air over the heat exchanger. The heated air is distributed through the ductwork. While innovative, this method of heating is not as cost-effective as either a furnace or heat pump. Expect estimates for the equipment and installation to cost $1,500-plus.
- Advanced Series water heaters also have an optional handheld remote that allows you to monitor and control all features including water temperature and the recirculation timer. The remote costs $75-$85 from various sellers.
How Navien Water Heaters Compare to Other Tankless Brands
Navien makes fewer models than the leading competitors like Rinnai, Takagi and Noritz, but the range of sizes provides most homeowners with a model to meet their hot water demand.
The T-H3 with its ultra-high efficiency and 199K BTU heater produces up to 11.2 GPM, one of the largest-capacity models on the market. The brand is considered a premium tankless water heater brand because all its models are condensing gas heaters with outstanding efficiency.
Having said that, about 20% of Navien tankless heaters have significant mechanical issues in the first 10 years. Leaks and failed control boards top the list. Navien’s heat exchanger warranty is 15 years, among the best, but it is essential that you hire a certified installer for the work. If you don’t, the warranty will be voided, and repairs won’t be covered from day 1.
