1. Rinnai RL75IN vs Rinnai RL75eN Reviews

Beginning this review, Rinnai RL75IN is best for larger families or households while Rinnai RL75eN is best for a family size of 3 persons. While you put that feature into consideration, we also look at the prices of each unit. 

Rinnai RL75IN prices are higher to the Rinnai RL75eN model and this is attributed to the heavy-duty materials that make it up. However, the first unit costs $1,471.00 while the later $1,014.52, so this is where your budget defines the quality and functionality of the water heater you desire. 

The Rinnai RL75IN features residential temperature settings of 98°F – 140°F while its rival Rinnai RL75eN temp wasn’t specified at the time of compilation of the reviews. Also, they both have commercial settings of 98°F – 160°F but you need to purchase the commercial controller separately for each of the water heaters. 

More so, the two Rinnai tankless heaters feature mc-91-1us digital controller and also installed with error code indicator that tells you if your heater is malfunctioning. Another similar, you find in these Rinnai tankless Rinnai RL75eN vs Rinnai RL75IN heaters is the thermal efficiency of 82%.

Also, they are powered by propane natural gas, which is considered to be more economical to electric tankless water heaters. Also, V65IP vs V75IP features the same energy factor of 0.82 and is made of imported parts assembled in the US.

Rinnai V75IP is listed $818.35 while Rinnai V65IP costs $671.45 and both are on sales on amazon. If you’re on a low budget but looking for a unit for homes of not more than 3 populations, I’ll advise you to pick Rinnai V65IP.

As for dimension, the V65IP measures 13.9 x 8.8 x 23.6 inches while the other V75IP measures 14 x 9 x 23 inches with 49.9 and 70 pounds respectively. However, the item size is not something you should worry about as either unit can fit into smaller spaces.

Talking on their water supply rate, I’ll give the rating to Rinnai V75IP featuring 7.5 GPM compare to its counterpart that features 6.5GPM. As for the BTU‘s rating, it goes to the Rinnai V75IP tankless water heater amounting to 180,000 unlike its rival of 150,000 BTU.

The 6.6gpm unit is designed with the lowest to highest water supply pressure starting from 20 – 150 but this isn’t specifying for the 7.5gpm unit. The manufacturer also stated that the Rinnai V65IP model meets Texas and California NOx emission standards.

However, to kill the augment revolving the respective unit of discussion, I’ll say the 2 DHW heaters are nice, but your budget will speak for your choice.

3. Rinnai RL94IP vs Rinnai RL94eP Reviews

Moving down to the features that put them off on different class then we’ll be looking at the area of installation. As for the Rinnai RL94IP model, it is designed for indoor mounting while requiring the vent to be directed outside the building. However, the Rinnai RL94eP model requires outside mounting which I suggest for those that have indoor space challenges to purchase.
