Title: Fairly easy to install, works well!
Review: I bought this to replace a standard tank water heater, I live in a smaller townhouse and I don't need a lot of capacity. It went in well, was easy to run the exhaust pipe through the existing heater vent. You'll probably have to buy the additional water polisher and the condensate neutralizing capsule, so it will be a little more expensive after everything is put together. Also, you may need to get into the BIOS and change the flow rate if you have a high efficiency washing machine. Mine did not draw enough hot water under the default settings to turn the heater on, but it's easy to change that, it's in the instruction manual.

Title: Easy Install and plenty of hot water
Review: Installed easily. Seem to use less natural gas than the old tanked water heater; and with an endless supply of Hot water. Set at 115 deg F and not mixing much cold water into the shower water.

Title: Really nice replacement
Review: I replaced my old water heater tank with this in less than 6 hours. It provides all the hot water we need and freed up storage space. I really like it.

Title: Amazing
Review: Product works as advertised, and installation was much easier than anticipated. Hot water has been endless, and with 5 people in the house, that is valuable. Electronic adjustments are supper easy. Only con would be the app and its functionality, we could never get it to work (but we don’t need it).I would recommend opting for the additional valves to make recirculating cleaning solution easy if you live in a hard water area.

Title: The best Water Heater
Review: There is nothing to dislike about this water heater. I absolutely love it. The water gets hot almost immediately. Now I don't have to pay for the propane to heat water. I would have purchased this years ago, but never new it existed. The plumbers discouraged me about buying it. They wanted to sell me their tanks. When I found a plumber to install it, they did a great job. This Rinnai looks great on the wall, and now have more space in my basement. It cost more than a tank, but it is worth every dollar I paid for it including the installation fee.

Title: 1 month of use
Review: I bought the Rinnai RX199iN as a diy-er to replace my broken water heater. The packaging of the product is excellent, The instructions are clear and will explained with lots of images to re-enforce installation methods. the connections are clearly mark which made the installation quick for a non professional.Things to know:It needs a power outlet near by.3/4 gas line preferredThis is a condensing unit, and it condenses a lot a water so be prepared to run a hose to a drain or a sink.Set up is difficult from the main panel easier from the app.The Rinnai APP, is divided into sections Owner and installer, and both have to have separate accounts, for some odd reason Rinnai made the installer version of the app a lot easier to use than the owner app. Once you register the product go back to the installer version to do any necessary temperature adjustments.The unit is not as quiet as a tank water heater as it does have some vibration and you can hear it when installed on 2X4 framing.but not a deal breaker.

Title: Hidden information
Review: I took out an older tankless unit. My first unit Was vented through my chimney and lasted 20 years. The reason why a condensing unit must be vented outside is because it will eat away at the chimney. That was hidden, parts for the unit are not readily available. The installation cost more than the unit.
