Sep 2023 Brief update: I had one occurrence of error 12 - flame out. But it hasn't happened again. I hope it was a fluke caused by our gas supply and nothing else. If not, I'll investigate and update my review afterward.
Original review Aug 2023: My recent experience with the Rinnai RU199iN tankless hot water heater has, in a single word, been excellent! It's like the ninja of water heaters - quiet and incredibly efficient in performance.
Getting it up and running was straightforward, similar to the typical expectations of setting up the necessary plumbing, gas, venting, and electrical work. However, it's important to note that this isn't like replacing a conventional tank where everything falls into place easily. Rather, it is like a fitting jigsaw puzzle into place, not easy per se, but not too daunting either. The most fun was renting a rotary hammer from Home Depot to bore the vent holes though brick.
For anyone worried about gas lines like me, you may appreciate this little surprise. The unit appears to have an internal gas booster pump. Ingenious, right? I chose to run it off of an existing gas line which was originally fed from a 1-inch line from the meter, with a brief downgrade to a 1/2 inch, before returning to a 3/4 inch. Despite my initial concern, it seems to function flawlessly under these conditions. But I am not complacent, and plan to eventually test all my gas appliances together in full throttle, just to be certain that the supply line capacity holds up.
One of the most commendable features of the Rinnai RU199iN? Stable hot water output. Not once did I experience any hot water fluctuations during use. An absolute win! However, I did notice a slightly longer delay to get hot water on a cold startup, taking approximately 10 to 15 seconds longer compared to traditional heaters. But once it gets going, it provides steady, continuous hot water supply.
Oh, and I must add - I did the installation myself. So, for all the DIY enthusiasts out there, this little project is quite manageable and rewarding.
In conclusion, the Rinnai RU199iN tankless hot water heater has proven to be a stellar addition to my home. It delivers consistent performance, minimal noise, and solid dependability. If what you're after is a top-notch appliance that couples functionality with ease of use, then the Rinnai RU199iN certainly fits the bill. Five stars for this one, without a second thought!
