Rinnai is a leading tankless water heater maker. All the heaters are high performance at least and ideal for the entire home, but they are still lightweight. Many are also Energy Star certified and use the latest available technology, such as WiFi allowed and operated by voice command, for example. In all of North America, these qualities have helped Rinnai become the single best-selling water heater company. Rinnai tankless water heater review is here.

Rinnai Tankless Water Heater review

Top 5 Rinnai Tankless Water Heater review

Rinnai was founded by Hidejiro Naito and Kanekichi Hayashi in 1920. The company began making cooking stoves in Japan. It grew to manufacture gas appliances in the 1930s. Water heaters became part of the arsenal in 1964, and Rinnai opened the first US office just 10 years later. 

Water Heaters with Rinnai Tankless Gas 

All Rinnai tankless heaters are efficient, giving you hot water on demand almost as soon as you turn on a tap. They have minimal temperature variations as well. You should expect to see about 40 percent in energy savings with a Rinnai device compared to regular versions from other brands.

Rinnai Electric Tankless Water Heater

You may have found that, in the above table, all natural gas or propane are the top Rinnai heaters. The electric heaters are not seen. In reality, a fast search for reviews of Rinnai electric tankless heaters will show you that Rinnai does not manufacture any electric heaters at all, tank or tankless, and never did. This is because Rinnai only manufactures water heaters that are efficient enough for at least an average-size home to heat the water. With electric heaters, which are often either a point of use or built for studio homes, it is too costly to do this.

Operating costs are another factor the business has opted to only manufacture gas heaters. While gas water heaters are more costly (due to both the purchase price and construction costs) in terms of upfront costs, the fuel to operate them will cost almost half as much as electrical power.

Rinnai Water Heaters Made where?

Until recently, all Rinnai water heater manufacturing was carried out in Japan. In 2018, in Griffin, Georgia, the company opened its first U.S.-based production facility. By 2020, this plant will be fully integrated with all locally-sourced components to manufacture water heaters.

Rinnai Water Heaters Styles 

Rinnai only manufactures tankless and hybrid water heaters today. Hybrid heaters are a cross between a tank and designs that are tankless. With less downsides, they deliver all the advantages of both old and modern technology. If you are looking to replace an obsolete tank water heater, hybrid units can be a good choice and you want to get the highest performance a Rinnai heater can bring.

Reviews of Rinnai Tankless Water Heater from Customers Online 

There are great ratings for most Rinnai water heaters and some have outstanding ratings. A general opinion among customers is that this product is a high-quality brand that is trustworthy. One thing that many customers appreciate is that as both indoor and outdoor heaters, almost all the models are available. This enables buyers to identify the most acceptable model for their requirements and then determine if it would be easier to install the heater inside or out of the building.

Reviews of Rinnai Propane & Natural Gas Heaters

There is no distinction between propane and natural gas heater ratings. The explanation for this is most likely that both propane and natural gas are available in the majority of versions. If it is for indoor propane, the name of the model is followed by iP, eP for outdoor propane, iN for indoor natural gas, and eN for outdoor natural gas.

In addition, this is possible for most models if you buy a propane heater and later need to convert it to natural gas (or vice versa). You literally have to buy a conversion kit directly from Rinnai.

All of this versatility is popular with customers, as Rinnai provides more customization and choice than the competition, as it is another way. This is just one of the many reasons why Rinnai’s customer scores are among the highest of all brands of water heaters.

Maintenance of Rinnai Water Heater

To prevent mineral buildup, Rinnai recommends that users clean their tankless water heaters once a year. Consumers say that this process is handled with ease. To check for blockages and damage, heaters also need an annual inspection. The units themselves are self-checked and inform users if there is a need for extra maintenance. On the front panel, an error code will appear that lets the HVAC professional identify the issue quicker.

Price of the Rinnai Tankless Water Heater

Most of their water heaters are priced higher than those of many other brands because Rinnai is a top brand. However, if you need anything more affordable, there are some budget choices that are well worth it. Prices for sales vary from as low as $650 to as high as $2,200. The greater the GPM and energy factor, as well as the higher the number of features, the greater the unit cost. 

Installation ranges from a few hundred dollars to more than one thousand dollars (for example, if a gas water heater is not set up in a home). Installation of outdoor heaters and indoor condensing units is less costly because they lack venting, but running the gas line to an outdoor heater will cost more. When they have recirculating accessories, installation costs can also increase for indoor models.

Warranty of the Rinnai Tankless Water Heater and Customer Care

The Rinnai water heaters all have a 12-year heat exchanger warranty, a 5-year general parts warranty, and a 1-year labor warranty. Consumers report providing outstanding customer service from Rinnai when a heater under warranty needs repairs.

The Top Tankless Models by Rinnai

High-efficiency, super-high-efficiency, and hybrid water heaters are available at Rinnai. No regular or mid-range versions exist. High efficiency begins at an energy factor of 0.79, and energy factors exceed 0.97 for hybrid models.

There are V models in the high-efficiency series and the high-efficiency plus has RL and RLX models. Until installation costs, all these heaters are very inexpensive and can provide hot water for between two and six showers at one time. 

To offer faster hot water delivery, high-efficiency plus indoor models use recirculation technology. This works by sending water back through the furnace to reheat periodically in the pipes. It removes the possibility of turning on the tap and waiting for the cold water to flush out for a while before the hot water can come in. This can lead to substantial water savings as a result. High-efficiency plus units use Circ-Logic technology which, during the initial installation, requires the addition of an external pump. 

Isolation valves and the ability for voice activation as part of home automation are a few other additional features of the high-efficiency plus models.

V75 tankless water heater

V75 tankless water heater

One of the cheapest Rinnai water heaters is the V75. For small and middle-sized houses, it is suitable. It’s more powerful with an energy factor of 0.82 than equivalent units from other brands. Instead of a pilot light, it also has electronic ignition and it uses Ultra-Low NOx combustion for minimum emissions. 

At temperatures of up to 140 degrees Fahrenheit, the heater will provide water, which features a hot water temperature lock to prevent incorrect temperature changes. As an outdoor heater, temperatures as low as -22 degrees Fahrenheit are shielded from it. The heater also has WiFi capabilities to remotely operate and track the device.

RL75 water heater model

RL75 water heater model

The RL75 is a luxury gas water heater, Energy Star-rated, suitable for medium and large homes. It uses a concentric vent-type system as an indoor model. One of the pipes brings fresh air in and the other is an outlet, horizontally expelling combustion materials through roof penetration through a single wall or vertically. 

To a great degree, the unit is able to modulate its flow. It can have a GPM of just 0.4 for low water needs, while it can go up to 7.5 GPM for elevated flow. The various safety components, including combustion fan RPM monitoring, automatic frost protection, and boiling protection, are other useful features.

RLX 94 water heater

RLX 94 water heater

Just like the RL75, the RLX94 is. The difference is that its maximum GPM is 9.8 and is only available with natural gas as an indoor model. It also complies with stringent emission standards for NOx. With the purchase of a commercial controller, it is possible to convert a standard RLX94 into a commercial device. This expands the range of temperatures to between 98 and 185 degrees Fahrenheit.

Super high efficiency series

The RUCS and RUS series consists of super-high-efficiency water heaters from Rinnai. They are more costly, but with a high energy factor of between 0.85 and 0.90., this additional expense comes with a high energy factor The condensing units are all RUCS and RUS models, which means that the exhaust gases they create a return to heat the water. This has two benefits: it improves productivity (and thus decreases running costs) and makes it easier to vent the water heater. In other words, the construction process is faster and easier, even though the heaters are more costly to buy. 

You have the RUC, RU, and RUR series of water heaters for super-high productivity plus. These have an up to 0.93 energy factor. For up to seven showers simultaneously, some may even have hot water. Furthermore, all of them are rated Energy Star and have the same extra benefits as the high-efficiency plus. The RUR models also go a step further, using ThermaCirc360 for recirculation instead of Circ-Logic. Instead of an external pump, ThermaCirc360 uses a built-in recirculating pipe, enabling even outdoor models to provide recirculation.

RUC98 water heater model

RUC98 water heater model

Because of its attractive appearance, the RUC98 is one of the most eco-friendly units available and is an excellent choice as an indoor heater. But the top-quality casing is not only for aesthetics, it also increases both indoor and outdoor heaters’ lifetime. 

To reduce combustion output, an indoor RUC98 can have either concentric or twin-pipe vents. In addition, the fact that PVC or CPVC (as well as PP) can be the vent pipe allows the installation quicker and gives greater versatility.

RUR98 Water Heater Model

RUR98 Water Heater Model

While it is costly to buy, due to its low operating costs, the RUR98 is a great investment for the long term. Concerning this heater, consumers have almost no concerns. The only downside they can name, in fact, is its bulky appearance. Nevertheless, while the heater may seem big, it actually takes up very little room, especially when you think it has a GPM of 9.8. 

This water heater is for you if you have high hot water requirements and want one of the most energy-efficient solutions available. The other versions in the RUR range are even larger if you need an even greater GPM.

Hybrid Series of Rinnai water heater

Finally, we’re coming up with hybrid ones. The RHS and RHS100 are these. Rinnai hybrid water heaters are pricey, but because of their elevated energy factor, they can be worthwhile. They do have recirculation technology and voice-activation capabilities, even though they are unable to handle simultaneous shower use. Plus, some are ranked Energy Star.

Where you can buy

On Amazon, all of the Rinnai water heaters recommended above are available. Each model can be found as an indoor and outdoor propane and natural gas heater.
