The unit is powerful enough to cater to the hot water requirements of small to mid-size homes as you can run a couple of showers or faucets simultaneously.
The IK-WV-200-1-XX-LF valve kit required for the installation purpose doesn’t come with the unit, and you need to buy it separately.
Some of my clients have complained about the unit making some random noise initially which later went away by itself.

On the downside, quite a few of my clients have found the instructions for routing the intake and exhaust confusing.
Noritz NRC71DVNG Indoor Condensing Direct Vent Tankless Water Heater
So, here I come with one of the most compact Noritz tankless heaters that we’ve on our list.
Like the aforementioned Noritz tankless, this little beast is also equipped with a built-in controller and an advanced heat exchanger design.
Definitely, the NRC71DV is a powerful unit and is capable of providing a flow rate up to 7.1 GPM which in layman’s terms means that you’ll not face any issue regarding the hot water requirement for a medium-sized home.
The powerful and compact Noritz tankless is also easy to install and emits low Nox.
In fact, if you’re currently using a 40-gallon water heater then it could be a good choice to switch to this Noritz tankless model as it will save you both space, and money.
Moreover, installation isn’t only easy but also comparatively less expensive as the unit can be vented with PVC.
Trust me, you can easily run a dishwasher and take shower simultaneously without worrying about the hot water.
You’ll not have to wait longer for getting hot water from even the farthest of the faucets.
The energy star Noritz tankless will provide you with on-demand hot water in less than a minute with a consistent output temperature and good pressure.
Like any other Noritz tankless heater, this unit is also backed by 12 years warranty on the heat exchanger, 5 years on parts, and a year on labor.
On the downside, a couple of my clients have had bad experiences in the past regarding customer support.
Noritz NR66ODNG Outdoor Tankless Water Heater
The Noritz NR66ODNG uses natural gas as a fuel and is capable of providing a flow rate of up to 6.5 GPM.
Moreover, the Nortiz outdoor tankless water heater is not only easy to install but also highly energy-efficient like the other models on our list.
However, you need to be careful that the unit is exclusively for outdoor installation and can’t be installed indoors.
Well, this powerful and compact little beast can suffice the hot water needs of 4 to 5 members living in a mid-sized 3 bedroom flat.
Though the installation isn’t a cumbersome task, in fact, it’s user-friendly, still, I would recommend you to hire a certified technician to prevent last-hour misadventure.
In simple terms, replacing a 40-gallon water heater with this gentleman would save you both space and money.
On the warranty front, the NR66ODNG has a similar warranty as the other Noritz tankless models on our list.
With 140,000 BTU/Hour the unit is bound to deliver high-performance with ease.
Since the unit is equipped with advanced technology so you don’t have to wait long for the hot water.
In fact, you can get endless hot water for even the farthest faucet in less than a minute.
Noritz NCC199-DV LP Direct Vent Condensing Tankless Propane Water Heater
The Noritz NCC199-DV LP is an energy star tankless water heater that uses propane as a fuel.
It is one of the most powerful Noritz tankless heaters on our list, and it is clearly visible from an output power of 199,900 BTU and a flow rate of up to 8.4 GPM.
Needless to say, the Noritz NCC199-DV LP can suffice the hot water requirement of a mid to large size family.
In fact, you can easily run a couple of showers and faucets along with a dishwasher and washing machine simultaneously without fear of a drop in water pressure or temperature.
However, in extremely cold conditions, the flow rate might fall because of the decrease in the incoming groundwater, and thus, the number of fixtures that can use simultaneously will also decrease.
The activation flow rate is as low as 0.05 GPM so as soon as you’ll open the faucet the trigger signal will be sent to the unit that you’re looking out for hot water.
Like the aforementioned Noritz tankless models, it is also compact and equipped with advanced technology in order to decrease the wait time for hot water.
In spite of using liquid propane as a fuel, the Noritz NCC199-DV LP has managed to maintain 93% thermal efficiency which is mind-boggling, and I give full marks to the manufacturer for it.
Not only is the installation process hassle-free but also affordable as less costly PVC can be used for its venting.
The manufacturer claims to reach the efficiency level of 93%, and the credit goes to the innovative technology used in this unit that captures the residual heat from the exhaust temperature to preheat the incoming water before it runs the copper heat exchanger.
And, of course, the Noritz highly efficient tankless heater is meant to last longer as it is made of durable elements such as stainless steel and copper.
If you’re using this little beast for residential uses then you get a warranty of 5 years on the heat exchanger, 5 years on parts, and one year on labor.
On the other hand, if you’re using it for commercial purposes then the warranty is 3 years on the heat exchanger, 1 year on parts, and 1 year on labor.
Noritz EZ111DVNG Tankless Water Heater GQ-C3259WX-FF US NG
So, here I come up with the most powerful Noritz tankless heater that made our list.
Trust me, Noritz EZ111DVNG is capable enough to take care of your entire home hot water requirement effortlessly.
Not only is the unit equipped with advanced technology but comes with a maximum water flow of 11.1 GPM.
Frankly speaking, the manufacturer wants to target the contractor with this EZ series offering and has inculcated the features accordingly.
The USP of the EZ111DVNG is the topwater connection that completely eliminates additional water piping requirements and thus saves you time in case you want to replace a conventional tank heater with this little beast.
On top of it, the Noritz tankless comes with multiple venting options, that is, direct vent, single vent, flex single vent, and outdoor exhaust.
Moreover, the device weighs 81 LBS and possesses an energy factor of 0.97 which is definitely something to boast about, isn’t it?
The unit could be a great fit for you in case you’re looking for a Noritz tankless that could cater to the needs of at least 5 to 6 persons.
On the other hand, I wouldn’t recommend this superlative little beast if you’re looking for a heater for a small home.
It goes without saying that like any other Noritz tankless heater, the EZ111DVNG is also highly energy-efficient, and will occupy less space as compared to a conventional tank-style heater.
Noritz Tankless Water Heater Buying Guide
It’s my humble request please do read this section carefully, and don’t skip even a single step or sub-section, as we would be vomiting each and everything that we known about the Noritz tankless heater in a concise manner.
However, if I’m not able to clear any of your doubts or missed any important points, then please feel free to reach out to us via email.
To be honest, one of the lesser-known, but well-respected manufacturers is Noritz.
Noritz specializes in the gas tankless water heater, and if you’ve NOT heard about this brand before, then stay with us as I would be giving you an overview of the Noritz product line-up.
Well, to begin with, Noritz is a well-trusted and highly reputed Japanese company that has been around for over 60 years.
If you’re not aware then let me tell you, they introduced their first electronically controlled tankless water heater way back in 1981.
And, in the year 2002, Noritz began its U.S operation and established offices in California and Georgia.
The brand actively participates in social media platform discussions and is also active on YouTube.
Not only do they sell the tankless heaters through physically present showrooms, but also, via e-commerce websites including Amazon.
In fact, you can contact Noritz via the contact form by clicking on this link or even by phone at (714)433-2905 or (770)422-8120.
Noritz prides itself on having some of the most durable, longer-lasting tankless water heaters on the market, and the best part is, they are highly affordable.
Still, not convinced?
Then, let me tell you, the brand Noritz boast of having some of the best warranties in the business.
Let’s look at some of the things that set Noritz tankless apart from the rest.
As per my knowledge and experience, the EZ series is Noritz’s most popular line of tankless water heaters.
What I liked about this product line is that it was designed to simplify the installation process for homeowners who wanted to swap out their tank-style heaters for tankless ones.
Just for your information, the EZ Series tankless heaters will save you both money and space as compared to tank-based conventional heaters.
Several of the Noritz tankless models are designed to work with the Noritz Connect app.
The process is simple and less time-consuming than you think.
All you need to do is to download the app, pair it with the Noritz tankless heater, and you’ll be able to remotely control your heater.
And, the best part is, the app gives you the flexibility to set up diagnostic and maintenance reminders.
In layman’s terms, Wi-Fi capability is an important feature meant to enhance usability and user experience.
Low and Ultra-Low NOx
The brand manufactures environment-friendly tankless heaters and offers a wide range of low and ultra-low NOx tankless water heaters.
In case, you want to know more, then click on this LINK.
With their low NOx emissions, the EZ units are prepared to meet not only the current code but also future revisions that might lower the maximum emissions level even further.
In simple words, the Noritz low-NOx tankless water heaters are future-proof.
Energy Star Certification
One of the reasons, why I recommend Noritz tankless heaters is because most Noritz tankless water heaters are energy star certified.
The benefit of purchasing an energy star appliance is that it is will not only reduce your utility bill but also, better for the environment.
Many of these models are eligible for the rebates, and so I humbly request you to go through the Noritz website to know more about the rebates as well as the models the qualify for the rebates.
Noritz Product Line
Well, my discussion would revolve around the three main Noritz tankless models.
I hope till now many of you would be aware of the fact that Noritz offers a wide range of high-performing indoor and outdoor models.
The NRC series are their high-efficiency models whereas the EZ series and the NR series are their mid-efficiency line-up.
Well, let’s talk about each one of them.
The EZ series could be a great choice in case, you’re planning to switch from the conventional heater to the tankless counterpart.
The EZ series comprises three main models and falls in the “mid-range” category.
EZ98 and EZ111: The reason why I’ve taken these two models together is that they are almost similar other than the fact that they vary tangibly in their sizes.
Moreover, the EZ98 comes with a UEF rating of 0.96 UEF and can deliver a flow rate of up to 9.8 GPM which isn’t bad at all seeing the price range of the product.
On the other hand, we’ve got EZ111 that is slightly more powerful, robust, and can be installed both indoor as well as outdoor.
You can expect this little beast to provide a flow rate of up to 11.1 GPM which is definitely something to boast about.
On top of it, the heat exchanger comprises stainless steel, and the brand boasts about the 25-year warranty that it offers.
EZTR40: Unlike the aforementioned models, which can be installed both indoor as well as outdoor, the EZTR40 can be installed only indoors.
It can deliver a flow rate up to 6.6 GPM and possesses a UEF rating of 0.87, and from this, you can clearly conclude that the unit would be a great substitute for an existing 40-gallon tank water heater.
The NR Series comprises seven models, and each one of these models is energy certified with a UEF rating of 0.81.
The brand Noritz has come up with the NR series to cater to the hot water requirements of small and medium-sized households.
Moreover, the maximum flow rate of these models falls in the range of 5.0 and 9.8 GPM.
The series gives you an option of both indoor and outdoor models to choose from.
The NRC series is one of my favorites and there are numerous reasons for it.
Moreover, the NRC series are highly energy-efficient and would occupy less space as compared to traditional tank heaters.
Many of you wouldn’t be aware of the fact that the NRC series is energy star certified and has a UEF rating between 0.89 and 0.94.
Furthermore, these appliances achieve a UEF rating of 0.94 and can deliver a water flow rate up to 11.1 and 10.1 GPM respectively.
How much does a Noritz tankless water heater costs?
To be honest, most of us can afford this high-quality brand if we can afford to spend as low as $500 dollars.
And, if you don’t have a budget constraint, then the brand has to offer you tankless heaters that can go up to thousands of dollars.
It goes without saying that the mid-range models are less costlier as compared to the high-efficiency models.
I recommend my clientele to go for the NRC series in case, they don’t have any budget constraints.
They might be costlier upfront but in the longer run, they will definitely pay you off.
Capacity and power are two important parameters that influence the price drastically.
Larger homes require units with more BTUs and a higher flow rate which is measure in gallons per minute (GPM).
In layman’s terms, the models that can deliver more hot water are simply more expensive so if you’re looking for a relatively powerful and bigger model then be ready to pay more price.
Noritz Tankless Water Heater Installation Cost
Depending upon the type of Noritz model, the installation cost varies.
Furthermore, the cost to install a tankless water heater is higher as compared to a tank-style water heater.
On average, it costs somewhere between $450 and $2000, and for more information, click on this link.
Almost all the Noritz tankless water heaters are backed by a 12-years warranty on heat exchanger, 5 years on parts, and a 1-year warranty on labor up to $120.
However, Noritz does have some exceptions, that is, installations with recirculation will be 12-years or 6500 hours of burn.
Certain models that fall under this category will have only a 3-years warranty on the heat exchanger.
It wouldn’t be wrong if I say exceptions also go in the other direction.
Some of the Noritz tankless come with even a 25-years warranty just like EZ111 and the EZ98.
Maintenance and Life Expectancy
Like any other tankless heater, the life expectancy of a Noritz tankless also depends to a large extent on the level of maintenance that it receives.
What I mean is, by performing regular maintenance, you can expect this little beast to last for almost 20 years.
Flushing is an important maintenance task that you need to perform regularly in order to remove limescale build-up within the heat exchanger.
Especially, if you’re living in an area with hard water, then you need to pay special attention to flushing.
In case, you want to know more about flushing frequency, then a plumbing professional would be the correct person to contact.
Furthermore, Noritz tankless wants the water to be conditioned or treated in case, levels exceed amounts listed in the owner’s manual if you want to avail yourself of the full warranty coverage.
Noritz provides all of the maintenance tasks in their owner’s manual.
You can also check a lot of videos available on YouTube that will help you with general maintenance steps.
Some Problems That You Should Know About…
As per my experience, the most common problem regarding a Noritz tankless heater is related to size.
From my past experience, I can affirm that most of the house owners commit the mistake of buying a very small tankless heater, just trying to save some bucks upfront.
Not knowing how to properly size a tankless water heater can also lead to buying either a smaller unit or a bigger one.
Another problem that can cause pain in your back is the improper installation of the Noritz unit.
Mostly the installation problem occurs with the models that come with the electronic monitoring feature and throws constant error codes.
The easiest way to get rid of such a problem is by contacting a certified technician for getting help in selecting the right Noritz tankless for your home.
Noritz Tankless Manuals
The manual that comes with most of the Noritz tankless is not only easily accessible but also easy to read.
Even though you’re a newbie, the manual would be of great help to you as it comprises of diagrams and illustrations.
Along with the user manual, the brand provides you with installation guides, warranty information, and also an e-book that you can download.
What I really liked about the brand Noritz is that it puts a lot and a lot of effort into educating its customers.
In layman’s terms, the more you know about your Noritz tankless model, the better you’ll be prepared for unprecedented events.
In this section, I would be responding to the queries related to the Noritz tankless heaters review in order to help you make an informed buying decision.
How to descale a Noritz tankless water heater?
Well, before we dive deep into the descaling process, let’s have a quick look at things that you’ll be needing for this process.
- A five-gallon bucket
- Two 3/4 inch connection drain hoses
- A submersible pump
- Three to four gallons of distilled, food-grade white vinegar
In case, you’re not familiar with the Noritz tankless model, then allow me to explain it to you.
The red isolator valve indicates the hot water side, and the blue isolator valve indicates the cold waterside.
Moreover, you’ll find the drain caps on top of the hot side and on the left of the cold side.
Turning the valves to the vertical position indicates they are “ON” and that the water is free-flowing.
And, turning the valves to the perpendicular position indicates they are “OFF”.
Below are the steps that are involved in descaling a Noritz tankless hot water heater.
