They also have a higher compatibility with your existing water system and longer-lasting parts so you can save money from the moment you purchase a unit. It’s time to get to know one of the best tankless water heater companies and why they’re a secret you’ll want to share.

The History of KD Navien Co., Limited

KyungDong Navien is a younger company, having been founded in 1978. Ten years later, it began making an impact by being the first Asia-based company to develop a high efficiency condensing boiler that was environmentally friendly. The company’s reputation grew as they achieved high-level certifications across several continents.

Over the years, KD Navien has expanded its products to include HVAC and numerous home systems. All of these share a focus on greener living and higher efficiency. Today, the company has two branches in Asia, as well as one each in Europe, Australia, North America, and South America.

As they are a younger company, their name isn’t as well-known as Kenmore, Whirlpool, or even Rinnai but KD Navien has worked hard to excel these older companies in both efficiency and environmentalism.

Tankless Water Heaters

Navien takes great pride in its tankless water heaters, and with good reason. These heaters have some of the highest efficiency ratings on the market and are also among the greenest. Two tankless lines are available, the NPE-A and NPE-S.

Common Features

All Navien tankless water heaters hold to a high standard, providing both ENERGY STAR and LEED certifications. They also use condensing technology to reduce your water bill and provide on-demand hot water with no wait time.

The controls are easy to use and Navien water heaters can both common vent up to 8 units and cascade up to 16 units, making them perfect for apartment complexes as well as single family homes.

NPE-S Line

The standard line is quite impressive on its own, and has many design features geared towards reducing installation costs. This higher affordability doesn’t reduce the level of quality, however. An outstanding .97 UEF rating makes this one of the most efficient lines on the market, and many of the components are designed to require less maintenance than non-condensing models.

NPE-A

The advanced line provides more quality than just about any other tankless heater on the market. Starting with a Uniform Energy Factor (UEF) of up to .96 and low NOx ratings, these units include ComfortFlow recirculation technology to eliminate cold periods.

To provide additional savings, the recirculation pump can be deactivated. These heaters can provide up to three LEED points and will help reduce your home’s HERS index score. The advanced series can also be Wi-Fi enabled with the NaviLink add-on.

Navien Tankless Water Heater Parts

When maintenance time rolls around, your Navien water heater shouldn’t be passed over. As with all tankless heaters, corrosion is less of an issue than with normal tanks, but some parts will wear out over time.

Valves, vent parts, and filters will all degrade over time. Electronic parts, such as the control panel, may also need maintenance once every few years to replace any loose or damaged components. When issues arise, pay attention to any error codes from your Navien control panel to help with troubleshooting.
