Impressed and some recommendations
I just moved in to my new place and the 50 gal traditional water heater was in need of replacement (hints of leaks surrounded the installation). It was a somewhat hard choice since money savings was just marginal. A tankless had high installation cost and it wasn't clear if it would be recovered with the lowered energy usage. However, the original tank was shoe horned into a nook and made maintenance difficult (e.g. can't easily replace the anode) and it would be nice to use the recovered space for a water softener. Decided on the RUR199i because of the reciculation feature. Installed and mostly working like a champ! Still struggling with the Control-R app for adusting temperature. Haven't called Rinnai yet. But there are some suggestions: Mount it on a wall away from living spaces if possible. There is a low hum when it is in use and if it is mounted on a shared wall with a living space, you'll notice it. The noise is especially noticiable when the reciculation pump is running. Use flexible connections if possible. Things are very tight and it'll save you quite a bit of time. I wanted a neat installation a with pressure valve and hose bibs and all pipes in-wall and that took most of the time. Workout connection locations with the unit on the floor and be aware of the standoff distances from the wall as the cold water connections is close to the wall and if not properly planned could lead to a lot of headaches ;-) If using hard pipe for the condensate drain, add a union to simplify future maintenance (e.g. if you need to remove the unit).

Satisfied.

Installed 6 months 1800sqft 2-lvl home, fast heating, quite operations. Only issue is on the simple thermal bypass for recirculation which is not very effective and results in too much warm water in the cold line. If using recirculation a dedicated line would be much more effective.

Inconsistent temperatures,
Customer review from logo
3 months old. Each time we turn on a faucet it varies in water temperature and how long it takes to get warm.

Installed by builder with new home purchase
Customer review from logo
It seems that it takes longer for hot water to show up at the faucet. I have scheduled the pump recirculation timing and not quite sure if that really helps in getting hot water sooner. Also, when running hot water it runs cold all of a sudden for a few minutes before turning warm (not hot). Have not been able to figure out the issue. However, the after sales customer service is great.

Too noise, is ticking and we can hear noise at out
Customer review from logo
Too noise, is ticking and we can hear noise at out main bathroom sink, also, there have been several occasions where someone will take shower and water is hot and goes cold while showering. This is supposed to be the best and is not , my old 20 years old GAS tank is better, I wish I had never changed it. Also, if the light goes out due to a power outrage, it will not work since it's electric and gas I guess. My old one was just gas and this never happened

Buttons work but app doesn't
Customer review from logo
The remote buttons are easy to re-program when necessary, and it's great to have instant hot water. Unfortunately, I only got the phone app to work for a few minutes and it hasn't since.

Best Tankless water heater around
Customer review from logo
Besides the fact that this is my 1st time having a tankless water heater, I was curious to know if I was going to experience the negatives about tankless. Well, I am so glad I put my trust in Rinnai because it does not need the waiting time that I thought it would, for the hot water, it is actually quicker than before (with a tank full of ready hot water). It is super silent (a very important factor for me) and very slick looking too (yes I have an aesthetic eye). I am so pleased with the purchase that I would recommend it to anyone looking to upgrade their water heating system. Why boil water if you don't need it? Why have your hot water sitting in a tank, most likely full of rust? Why have it take up precious space in your house? WHY disregard all this AND be accepting of the high hydro bills that come with it? Changing to Rinnai tankless has been a win win decision for me!

We like pressing a button to start our water heating instead of running it down the faucet
