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
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.
