So far (2 weeks after install), this unit appears to be working as advertised. It performs consistently and we've not yet pushed the limits enough to run low on hot water. While you do get 'endless' hot water, there is a limit to how much it will make at once. In our area, the temperature rise required (delta T) is about 50 degrees. So according to Rinnai's website we should expect about 8 gallons per minute from this RUR199i, not the 11GPM mentioned in the title. The only (very) minor issue we've had with this one is that the manual is incorrect in the parameter settings for the recirc frequency. The settings for 'comfort' (6 cycles per hour) vs 'economy' (3 cycles per hour) are reversed from the documentation. I've verified this with a temperature logger. (Yes, I'm that much of a nerd). Beware installing this unit if you don't have significant experience with plumbing, venting and/or electrical. I would also recommend the add-ons that I've done to mine. I've installed a small thermal expansion tank on the cold side between the unit and the check valve to keep the pressure on the hot side from constantly spiking to 150PSI. And I added a UPS (uninterruptible power supply) on the power feed to help with short power outages. The wifi app that comes with it is very kludgy, buggy and barely functional. They should definitely invest more there to make it more functional and stable.

    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).

      Not efficient
      I bought this unit over 1.5 years ago. I replaced a tanked electric water heater in the garage. After looking at lots of my own usage and data, converting energy units, the result was this saved me about $10 over a year compared with my previous tanked electric water heater. To make things worse natural gas is about 1/3 the cost of electric where I'm at, when taking into account units of energy. Of course, I do have endless hot water, which is why this review is 2 stars and not 1 star.

        Good Product
        The reliability of the water heater is excellent. We previously had another brand tankless water heater and it frequently had to be reset to provide hot water. That can be a problem when you are in the shower and you have to reset to continue receiving hot water. In the eight months since we purchased the Rinnai not one problem and the hot water is delivered faster than our old tankless system. Very pleased.

          Excellent design, very quiet to operate. Water is at temperature and no loss of pressure, we got the one with circulator to constantly have hot water at the faucet without waiting. Unit is very cold around in the exterior

          Heat Exchanger leaks
          Heat exchanger began leaking at 6 months. Installer indicated they could not get parts, unfortunately waited to call Rinnai until after one year had passed. Took numerous calls to Rinnai CS to get response on warranty, would not respond as promised. Would not cover labor to replace and only replaced heat exchanger after water dripping over electronics for 6 months. Cost $904 to replace heat exchanger, but Rinnai would only supply heat exchanger (lower expense for them). My plumber suggested Rheem or A.O. Smith, should have listened.

            Works amazingly well
            Exceeds my expectations. Provides hot water within a few seconds if it has not been used recently and it is quiet.
