Rinnai RL94iN A Newer Model of R94LSi
A newer model of the previous R94LSi is the Rinnai RL94iN. This luxury series tankless water heater, like the R94LSI has been reviewed favourably online by customers who purchased it from different websites.
There is also the another model under this series that utilises propane as a fuel; Rinnai RL94iP.
As compared to R94LSi, this new model has some new improvements, which I have included in my unbiased review below.
Benefits of owning a Rinnai RL94iN
Production Capacity of 9.4 GPM
With a production capacity of 9.4 GPM, there is no fear of hot water running out for your household with the Rinnai RL94iN installed. In fact, it can provide hot water to up to 5 plumbing and appliance units simultaneously.
Compact and sleek design
This Rinnai tankless water heater has a compact and sleek design that does not take up a lot of space upon installation unlike a tank water heater that will come with a storage tank. However the RL94iN can only be installed indoors only and is certified for installation in mobile homes.
Digitally controlled temperature setup
Adjusting and troubleshooting of this tankless water heater is controlled by an in-built control panel digitally (MC-91-2US) and ranges from 98 Degrees Fahrenheit to 140 Degrees Fahrenheit.
Similarly like the R94LSi, the RL94iN can also be installed together with an additional temperature controller: MCC-91-2US that can increase the maximum temperature from 140 to 185 Degrees Fahrenheit. This option is available for commercial or hydronic purposes.
Runs on natural gas or propane
As compared to oil and coal, natural gas is the cleanest fossil fuel in terms of emission, with the least emissions in terms of sulphur dioxide and nitrogen oxides, with virtually no ash or particulate matter released. Propane is also a viable alternative fuel source, like natural gas is non-toxic to the environment.
Green Product
Rinnai RL94iN is an Energy-Star® certified product with its thermal efficiency of 84% and energy factor of 0.82. It also meets California and Texas NOx emissions standards. Its energy factor of 0.82 also means that installing a Rinnai tankless water heater will qualify you for a $300 US Federal Tax Credit
Besides that, being a tankless water heater there is no costs incurred on the standby power that is required to maintain the temperature of the water in the storage tank of a traditional tank water heater.
Additional Functions
The enhanced scale detection function, which will control and lessen the formation of mineral scale deposits (limescale) in your tankless water heater, especially for areas with “hard” water is included in the Rinnai RL94iN and not for R94LSi. Thus this will increase the life expectancy and ensure the efficiency of your unit.
This is important because limescale build-up will lead to a drop in water temperature, resulting in more energy required to maintain your desired temperature. Extensive usage of hard water will also lead to a drop in life expectancy of your unit.
The built-in Rinnai Circ-LogicTM recirculation program for this Rinnai tankless water heater controls the on/off sequence and operational cycles of the recirculation pump based on key variables like the length of recirculation loop, piping insulation, and the homeowner’s comfort and efficiency preferences. The in-built temperature lock function that also prevents the accidental or unauthorised changes to the water temperature.

Customer Reviews on Rinnai RL94iN
I have read many customer reviews for Rinnai RL94iN from verified purchasers and have summarised them below.
Installation and assembly
It is recommended that a professional is engaged to install this unit if the buyer has not much experience in installation and plumbing. Nevertheless, there were cases that the installer was the customer himself/herself. The provided documentation was commented to be insufficient though any required documentation for this unit is all available online.
Functionality
Quality workmanship, quiet mode of operation, space-saving design and the ability of the RL94iN to keep up with demand when it’s needed were mentioned fulfilment in terms of functionality. One unit of RL94iN, as mentioned by a customer, was able to support two showers and laundry without running out of hot water.
Consistent hot water production, with minimal fluctuations in temperature, was also frequently mentioned by customers. However, there were cases of fluctuation in temperatures mentioned though it was due to more of the inherent water temperature due to seasonal effect and not the capability of the unit.
Another asset was the savings in utility bills that were enjoyed by customers making it a green product worth considering. However, one mentioned con by customers would be the inability of the unit to function at places with low inherent water pressure due to its optimum range of 30 to 80 PSI.
Customer Service
Multiple reviews from customers have commented that Rinnai did not honor their coverage criteria in their warranty, with poor support from their dealership.
Warranty
There is a limited warranty that comes with the Rinnai RL94iN. The heat exchanger is covered for 12 years for residential usage only, 10 years for residential and space heating, and 5 years for commercial settings. There is a 5 year warranty for the other parts and 1 year labour warranty coverage.
