There is always plenty of hot water. But, it take
The continuous hot water is a feature that we like. The unit hanging on the exterior of the house is a bit of a distraction from the beauty of the exterior. We have been using it since we moved into our new home on January 21, 2022.

    !Why did I wait so long?
    We’ve had our Rinnai for 6 months and could not be happier! Do not fear the cost or any negative Nelly’s that you’ve heard from before, take my word, I only wish I had put one in 12yrs ago when we built our home. Not only is it easier to adjust the temperature, plus more efficient, I find it to be a downright attractive piece of equipment. Kudos to Rinnai!

      Cost saver.
      I had my first unit for 15 years before I had to replace it with another Rinnai. I believe it is a cost saving device.

          Space saver
          We moved to a tiny house with little space in the laundry room. Our Rinnai was installed outside allowing for much more storage.

            Wise decision
            We have the outdoor gas Rinnai and couldn’t be happier! We never run out of hot water and the energy savings has been phenomenal! Thank you Rinnai

              Replacement for 20 year old Rinnai, RIP.
              This one is much more efficient, has higher flow and was installed correctly outside which opened up a lot of space inside.

                No Regrets
                I have the water heater in a vacation rental. It saves me money as the heater is on a separate gas line and only uses gas when someone is actually using hot water. When the house is empty it costs nothing. Rinnai has the best rating for reliability and I have had no problems. The first one lasted 12 years and I have had this one 2years. Couldn't be happier.

                  It is a small tank and its installation is outside
                  I was surprised by the size and efficiency of said Gas Hot Water tank, also the quality is much higher than what I expected and the price is accessible

                    Works great
                    We’ve had the Rennai tankless water heater for 2 months. It produces endless hot water and saves a ton of LP gas used to heat a regular tank water heater. This is especially important now that LP has prices are 40+% higher than last year and continue to climb. My tankless water heater will pay for itself much sooner in savings as a result of using much less LP to heat our water.
