In this review, we’ll cover the main talking points surrounding all tankless water heaters, including:

  • Brand history
  • Cost
  • Efficiency
  • Warranty 
  • Availability
  • Variety
  • Additional features

By touching on these topics, we’ll give you enough information to help you make an informed decision when it comes to your tankless water heater upgrade.  

Let’s jump in by getting to know the history behind the name Noritz. 


Noritz Brand History

  • Founded in 1951
  • Introduced the first electronic tankless water heater in 1981 
  • Invests in contractors with training and other media

Noritz is a Japanese company that was founded in 1951. The company arrived on the scene by launching a new type of bathwater heater. From there, Noritz continued to evolve its water heating technology, and in 1981 it created the first electric tankless water heater. 

With over 60 years of tankless water heater experience, Noritz has built a reputation for industry-leading innovation and is trusted by many reliable contractors. In fact, Noritz takes pride in the contractors it works with and offers them training and even has a podcast to keep interested contractors and customers up to speed. 

While all of this sounds nice, we have to address the elephant in the room: cost. 


How Much Do Noritz Tankless Water Heaters Cost?

  • Higher cost than competitors like Takagi
  • $1,200 to $3,200 without installation

As you might expect, with such a strong reputation, Noritz isn’t the cheapest option on the market. Tankless water heaters are already more expensive than tank-style water heaters, and that price only increases with brand recognition. 

A Nortiz water heater on its own will run you about $1,200 to $2,300. Installation can increase the total cost of a Noritz water heater to between $4,700 and $8,300, depending on which contractor you choose and the available installation packages.

But with an investment like this, you’ll need to ensure you’re covered in case issues arise. Luckily, Noritz provides some of the strongest warranty coverage around. 


What to Expect from a Noritz Tankless Water Heater Warranty

  • Up to 25-year warranty
  • Unrivaled warranty term

A typical tankless water heater warranty is around 12 years. Noritz crushes the norm by offering up to 25 years of coverage on select models. Considering tankless water heaters last from 12 to 25 years, depending on if the heat exchanger is copper or stainless steel, this is especially strong coverage. 

The second-best warranty on the market comes from Navien, which led the pack for some time in the warranty department. Navien’s warranty hits the 15-year mark. 

Noritz’s top-tier coverage adds an additional layer of security when it comes to protecting your investment and is unrivaled in the space as of this article. Speaking of making the most out of your investment, what can a Noritz really do for you aside from providing hot water?


Noritz Tankless Water Heater Efficiency

  • Up to 98% efficiency
  • High-efficiency models qualify for maximum California rebates and federal tax credits

Tankless water heaters are synonymous with efficiency, but some models are built differently than others. Noritz is one of a few manufacturers that makes high-efficiency tankless water heaters. The brand touts up to 98% efficiency, meaning your home will be more eco-friendly and waste less energy. 

Noritz’s high-efficiency models also net the additional benefit of the maximum California rebate of $1,000 and the maximum federal tax credit of $300. Putting money back in your pocket is seldom seen as a negative, so if you choose a high-efficiency model, you’ll get a little extra in return. 


Are Noritz Tankless Water Heaters Readily Available?

  • Readily available
  • Easy Los Angeles County access to parts

Despite being a popular option for many contractors, Noritz tankless water heaters aren’t in short supply. The company makes it easy to get your hands on just about any model in its inventory. If you’re in Southern California, you also have the added benefit of being close to Noritz’s headquarters, making replacement parts that much more accessible to local residents. 


What Kind of Variety Can You Expect from Noritz?

  • Copper and stainless steel heat exchangers
  • EZ line makes converting from tank-style to tankless easy
  • Variety of models for different sizes of home
  • Indoor and outdoor models

Noritz provides a wide range of options, from single-fixture tankless water heaters to residential options that can service homes with up to four bathrooms. Along with this flexibility, the company offers innovative designs like its EZ models. 

The EZ line is ideal for homeowners transitioning from a tank-style water heater to a tankless one. Noritz’s design allows for easy hookup to existing gas and water lines thanks to an inverted design.

The stainless steel heat exchanger is a relatively new breakthrough in tankless water heater technology. While Navien offers only stainless steel options, Noritz stocks copper and stainless heat exchangers. This variety adds a little wiggle room to pricing on the less-expensive copper models. Copper models are expected to last from 12 to 30 years with maintenance, while stainless steel versions will run from 15 to 25 years with maintenance. 

You’ll also find both indoor and outdoor tankless water heaters in Noritz’s lineup. Providing both options to customers gives more flexibility in where you can install your tankless water heater. 


Additional Features

  • Wi-Fi controllers
  • App-based support and reminders
  • Remote Starts

In terms of extra bells and whistles, Noritz is up there with Navien when it comes to providing a well-rounded set of expected and experimental features. Most recently, Noritz has implemented Wi-Fi controllers, app-based support and reminders, remote starts, and other features. 

While a standard tankless water heater will serve you just fine without the added bells and whistles, Noritz is constantly striving to make the tankless water heater experience more convenient and integrated. 



  • Reputation
  • High-efficiency
  • Qualifies for maximum rebates and credits
  • Widely available
  • Strong variety
  • Best warranty in the industry
  • Additional features on offer
