Noritz vs. Rinnai

Noritz vs. Rinnai... which tankless water heater is better?
As there are many inquires online about comparing Rinnai and Noritz water heaters, I will try to cover their main advantages so you can actually decide or find the answer which tankless water heater is better.

Both Noritz and Rinnai water heaters are coming from Japan and using the same tank-less technology. They both heat the water. They both have great 12-year warranty. All the units are Energy Star qualified and have burners with the low NOx emission.


Noritz vs. Rinnai - Comparison

But, lets compare two the largest Energy Star models for residential hot water applications: Noritz NR98-DVC and Rinnai R94 LSi.

Noritz NR98-DVC with 11,000 min/199,900 max. BTU/hr for both natural and propane gas outperforms Rinnai R94 LSi which is designed for 15,000 min./199,000 max. BTU/hr for natural gas (190,000 for LP).

Noritz NR98-DVC outperforms Rinnai R94 LSi in capacity range also: 0.5-9.8 gpm vs. 0.6-9.4 gpm.

Noritz tankless water heater has a built-in pump control for recirculation application while Rinnai doesn't.

Noritz is equipped with the heat exchanger made of the commercial grade copper which is 25% thicker than Rinnai.

Noritz is equipped with the dual flame burners, to maximize the output, provides temperature stability, and maintains low emissions. Rinnai has single flame burners.

Noritz uses stainless steel casing on all ASME commercial units, while Rinnai don't.

Noritz offers more tankless water heater models and higher flow rate (commercial models are with the 13.2 gpm, residential 9.8). Noritz manufactures units for hot water production and radiant heating applications while Rinnai doesn't.

Rinnai has more condensing tankless water heater models in its offer; with the 8 and 9.8-gallon water flow and for indoor and outdoor installation.


Noritz vs. Rinnai - Price

Amazon: Rinnai R94 LSi costs $1400; on sale is $1100
Google product: Noritz NR98-DVC is $1150

Conclusion:

Bottom line is, according to the above review and comparison, both tankless units are great, long lasting with great features. What I personally like is that Noritz manufacturer builds and quality controls almost all of its parts, they do not outsource the work.

Which one you are going to buy depends on your budget, personal preference, availability in your area and customer service. It is easy to buy a water heater but if you don't have the reliable tech support, available replacement parts and technicians when you need it than think twice.

Noritz Vs Rinnai
by: Anonymous

I am in hvac sales , and i have sold both the products. But i have noticed that people tend to like the Noritz brand more than Rinnai, both customers and installers alike. Installers love the fact that they can use the condensing model of Noritz for any house and also the venting pipes are cheaper as they use a 3 inch venting, where as most of the Rinnai models use a concentric venting which is more expensive than regular 3 inch pvc pipes.

Hope this helps people make a better decision when it comes to chose a brand

Which brand is best - Noritz or Rinnai?
by: EKN

I have the 9.8 g/min Noritz for my master bath which replaced a tempermental Rinnai. I am also replacing an old tank heater with the newer condensing Noritz 11 g/min for the remainder of the house. Noritz always wins over Rinnai when you do the side-by-side. I'm only going with Noritz from now on.

Rinnai vs Noritz tankless heaters
by: Anonymous

I can buy and have installed either of the heaters mentioned in the article for approximately $3200. it is hard to discerne the difference without digging into it. This article was very helpful in making my decision. Clouding the issue, I think Rinnai does a better job of advertising. I will opt for the Noritz.
