Why it Stands Out to Us
Noritz EZTR40NG is an advanced upgrade to your regular 40-50-gallon water heater. It can easily sustain a full household with hot water. It stands out to us due to its built-in safety devices. Flame Sensor, Overheat Prevention Device, Lightning Protection Device, Freeze Protection, Condensate Overfill, and Fan Rotation Detector all protect it from running issues. Its preset temperature controls provide you with water at just the right temperature you desire.
Plus, given its compact design with a sleek and modern finish when mounted inside your house, it won’t look odd. All of these have made it the runner-up on our list.
If you are looking to replace your old large capacity water heater, this is certainly a great option you should consider.

Best for the Money:

Why it Stands Out to Us
This Noritz model stands out to us because of its price. It is a great device that heats water indefinitely in a very efficient manner. It saves a lot of money because of its high energy efficiency, and it works quite well. You do not have to change anything about how you use your hot water fixtures. Just turn them on and wait for the hot water to start flowing.
The Eco Tough design reduces both energy use and carbon dioxide emissions, cutting down hot water costs by nearly 50% compared to a tank-based water heater. All of these great efficiency features combined with a long life and high-reliability standard ensure that it will serve you for years.
This Noritz product is the best purchase for the money. That and all the energy-efficient features make it one of the best tankless water heaters available on the market. Although annual flushing is recommended to maintain it in its top shape, it is still worth its price when it comes to performance.
Other than that, it is quite easy to install and operate. It surely lives up to its claim of infinite hot water supply. It uses new high efficiency, low installation cost PVC venting to take tankless installation costs to a new low. We highly recommend this product for its cost, sturdiness, and quality.
Best Noritz Tankless Gas Water Heater:
Why it Stands Out to Us
Noritz NR66ODNG is one of the best tankless water heaters that work on gas. It can surpass any large capacity tank-based water heater in terms of overall cost and efficiency. The built-in display makes it easy to adjust to your needs. It has a compact design and is easy to carry around.
The unit also comes with manual and user-friendly instructions. It can be a do-it-yourself project for some, but others might need professional help. It might take up a lot of gas, but it does not waste much of it. If you do decide to install it, it is going to save you a lot of money.
When it comes to gas-operated water heaters, this is the best model Noritz has ever produced. It can easily sustain a large household’s demand for hot water. The best part about using an outdoor tankless water heater is that you don’t need to worry about installing any vents. It is a reliable option for outdoor applications.
You can use it with both propane and natural gas. It is quite energy-efficient with a heating range from 100 to 150 degrees F. It has all the signature Noritz features, which make it a dependable, versatile, and long-lasting product that you should seriously consider.
Best Noritz Outdoor Tankless Water Heater:
Why it Stands Out to Us
Noritz NR50ODNG is the best tankless water heater for outdoor installation. Being an outdoor model, it is free of vents. But it needs space upfront because it vents out from the front. When compared to other tankless models, it is quite affordable. It is suitable for an average-sized household with 1 or 2 shower heads.
It paves a way towards a better lifestyle by supplying continuous hot water when needed. It features a compact design that can be easily installed in a tight space. It has a high-performance single flame burner that can automatically adjust its level. All of these qualities have made it one of the best outdoor tankless heaters that Noritz has produced.
This product is certainly the best choice for outdoor installation. However, it should not be left in freezing temperatures because that can damage it. Its direct ignition makes it easy to use. As an outdoor model, it does not require expensive venting, but it does require an open space installation for venting purposes.
An automatic air regulator keeps a check on the internal temperature and adjusts the burner accordingly. A PC-coated exterior is made to last and protects the unit from all external elements. Combine all of this with its pricing and cost-efficiency, and you have the best outdoor tankless water heater that can satisfy all your requirements.
Best Noritz Commercial Tankless Water Heater:
Why it Stands Out to Us
Noritz NCC1991-ODNG is the product that stands out to us as the best for commercial applications because it has innovative construction. It has high-quality features that will make it worth your money. Made with high-quality copper, the primary heat exchanger is of great quality.
The stainless steel secondary heat exchanger transfers heat efficiently. The casing is manufactured in high-quality stainless steel also. All these classify it as the best commercial-grade tankless water heater from Noritz.
If you’re looking around for a new or substitute water heater for your restaurant, hotel, office, or your large home, getting the appropriate commercial water heater is critical for you. Noritz NCC1991-ODNG is a good option you should consider because of its high-quality and energy-efficient standards. This is the safest option due to the freeze protection, neutralizer refill, overheat prevention device, a lightning protection device, and flame sensors.
It also saves you some extra cash by making sure you do not have to pay for damage repairs. With the 5-year limited parts warranty, this product is a perfect option for the money.
What Kind of Warranty Does Noritz Offer?
As stated above, Noritz provides comprehensive warranty coverage on all its products. The warranty is only effective on appliances that are installed by Noritz authorized personnel. Their warranty terms include:
- 12 year heat exchanger replacement for residential and 2 to 5 years on commercial models.

How to Descale a Noritz Tankless Water Heater?
No matter what kind of water heater you install, scale build-up is the biggest issue that interferes with performance. The risk ratio is the same for tankless and tank-based water heaters. Although the chance of corrosion is fairly low in tankless water heaters, it is not exactly zero. That’s why tankless water heaters require annual flushing to descale the build-up that has deposited in the system.
Because of its innovative approach, Noritz has developed durable and sturdy products. To back it up, it has come up with an effortless descaling method. Although you can descale it yourself, it is best to seek a professional to do it, so you don’t end up voiding the warranty on your device.
The descaling procedure involves the following steps.
- Turn off the gas, hot and cold water valves.
- Take off the drain caps on hot and cold pipes.
- Place a five-gallon bucket under the hot water side.
- Turn on the hot water valve and capture the leftover hot water in the bucket.
- Repeat for the cold side.
- Connect the hose with your submersible pump and put it in the bucket.
- Put the end of the drain hose into the bucket to empty it.
- Pour 4 gallons of vinegar into the bucket. Make sure the pump is completely submerged in vinegar. It’s also important to open the drain valve lever handles on the isolation valves. Let the pump run for an hour or so.
- Turn the hose off after an hour. Remove it from the cold water drain valve, and then put the cap on the drain valve outlet.
- Now take the drain hose and the pump away from the bucket. Drain the liquid and put the hot water hose back in your empty bucket. Open the cold water main valve. This will flush the heater with fresh and cold water. Let it go on for five minutes. You can leave it until 20 gallons of water have entered the heater.
- Now unscrew and take the water filter out for some cleaning. Use some water to flow it out. Run the filter under water to remove all debris. After putting the dry filter into its port. Carefully tighten it by hand.
- Turn off the drain valve. Now remove the drain hose and replace the drain cap. Screw it on really tight.
- Finish the process turning the primary cold and turn on the hot water valves. Don’t forget to switch on the gas supply again.
- Descaling can sometimes cause an error code 11. To solve this issue, reset the water heater by simply turning it off. Turn it on again in the end.
