High Performance, High Capacity for the Busy Household
We’re continuing our extensive reviews of tankless water heaters, and Rinnai came out on top again for mid-size to large homes. The RL75iN tankless water heater from Japanese manufacturer Rinnai reliably and efficiently provides hot water for up to three showers at one time.
If your home needs a constant supply of hot water, or you find yourself running out of hot water at peak times, you will enjoy the benefits of replacing your traditional water heater with this indoor tankless model. It’s smaller than traditional water heaters, and you’ll never run out of hot water. It is also compatible for recirculation to ensure that you always have hot water as soon as you turn on the faucet.
If you’re replacing your current tankless water heater, note that the RL75iN provides 7.5 gallons of hot water per minute. If your needs fall at or below this flow rate, you will undoubtedly be pleased with the RL75iN’s performance and user-friendly controls.
Is It Worth Your Money?
The Rinnai RL75iN indoor, natural gas water heater will outperform any traditional (tank) water heater both in hot water delivery and longevity. It constantly heats your water as it passes through the heat exchanger, so as long as you’re not using too many fixtures at one time, you’ll never run out of hot water. You can also expect the unit to last 20 years, whereas a tank water heater will fail after 10-15 years.
You’ll also enjoy being able to install the RL75iN in any room of your house. It takes up a small amount of wall space, has an attractive appearance, and is easily accessible with a temperature control setting of 98-140-degrees Fahrenheit.
You will rarely need to perform any maintenance on this tankless water heater, and the company provides a 12-year warranty on the heat exchanger (5 years on other parts). If you want added convenience, you can add a recirculation pump that keeps hot water pumping and reheating through your pipes at all times.
If you do not need 7.5 gallons per minute, however, you would do well to consider the smaller Rinnai V65iN model, which provides 6.5 gallons of hot water per minute for approximately $500 less than this nearly $1200 model. That being said, if you do need a higher flow rate the RL75iN won’t disappoint you, and with an expected lifespan of 20 years, the convenience is well worth the initial investment.
Detailed Review & Breakdown
The Rinnai RL75iN tankless water heater will benefit nearly every home, but before you buy, here’s what you should know. We’ll detail the features, specifications, ease of use, installation requirements, pros and cons, and the cost of purchasing the RL75iN for your home.
Is This The Tankless Water Heater For You?
Heating 7.5 gallons per minute, the Rinnai RL75iN is sufficient for families of 5-6 or those who need a large amount of hot water at peak times. If you have a large home, install the water heater in a central location between bathrooms and the kitchen to minimize wait time for hot water delivery.
The Rinnai RL75iN does jump in price compared to lower capacity models, but that extra gallon of water per minute does make a difference. Five hundred dollars spread out over 20 years is a negligible amount to pay for the convenience of supplying your whole family with hot water.
This model rarely fails or needs maintenance, especially if you soften your water. You can also add a recirculation pump to the system for immediate hot water.
Overall, we’re impressed with the Rinnai RL75iN and would recommend it to any family with the need for an increased hot water supply.
Other Options Worth Looking At:
If you don’t think that you need quite that amount of hot water at any one time, we recommend the smaller Rinnai units, such as the V65iN or the RUCS65iN, which will also help you save on your natural gas costs.
If you need more hot water, Rinnai offers hybrid models with up to 40-gallon tanks that continually refill to meet the needs of even the busiest home. They also offer propane counterparts for all of their models if you would rather use a different fuel source.
