Performance Platinum 9.5 GPM Natural Gas High Efficiency Indoor Tankless Water Heater

Heavy condensation coming out within the unit. It does not go to the condensation drain line. No hot water provided. Were not able to contact Rheem Tech support for help after 5 phone calls. Replaced it with Navien Water heater. Installation is the same. No condensation at all. Works just fine. Rheem does not seem to have good quality tankless water heater. It was a brand that my first licensed plumber refused to install. Should have listened to them.

Our old hot water tank wasn't keeping water hot enough for me to finish washing the conditioner out of my hair. While the installation was a bit tricky for this the hot water has been unlimited and we love it.

My water has calcium (salt) in it, and tank water heaters didn't last more than 18 months for me. So tankless has been my only real option for the last 20 or so years. Also, I have a well pump and so water pressure varies constantly. The first heater was archaic by today's standards; minimal electronics, a pilot light, crude (terrible) temperature control, etc. After about 5 years, it caught fire - thankfully I happened to be in the basement at the time, so I could shut it down before any real damage occurred. The next one was a Bosch Aquastar. A major improvement, but still not a great performer. The water temperature was rarely consistent or steady. Showering was possible, but problematic, often adjusting the temperature between steaming hot and freezing. That one finally died too, after about 10 years. The Reem was pretty straight-forward to install, though I had to move pretty much every pipe because there's no standard. It started up and ran like a dream immediately. The shower temperature in particular was the prize. It's perfect. No adjustments what-so-ever, regardless of flow/pressure. And I could run it for hours if I wanted to. Yeah, it was a bit pricey, about $1,600.00 all told, but if I get 15-20 years this time, at this performance level, it's worth it. Note: Get the flush valve kit! Yes, it's a bit extra, but my old one died for lack of back-flushing, mainly because it was a pain to set it up and run it. But with the valve kit, it's really a breeze. All you need is a portable pump, a couple of laundry hoses, a bucket and vinegar. Once or twice a year, run it for about 1 hour. I plan to. I think if someone installs one of these on a better water supply, like city water, they'll get even better results.

These On Demand water heaters take up a lot less space than a traditional tank heater. It provides plenty of hot water and was installed to address the need of filling a new whirlpool tub after a bathroom remodel project. Our older 40 gallon tank heater ran out of hot water before the tub was filled. It works well. The reason I give it 4 stars is because you will use, overall, more water which offsets the savings the tankless unit provides. It takes a long time to remove the cold water in the pipes before the hot water comes through. Once it gets there you will never run out and it is hot. We are finding we need to run the water much longer than we did with the tank water heater. Our situation required going with a tankless heater for the tub. My suggestion is to think through your situation and take this into consideration when making your decision.

no adjustments needed, installed and worked perfectly after turning it up to 120*. saved a ton of room!

Very good tankless water heater. It runs very quiet compared to another brand I have at my office (sounds like a vacuum cleaner). We have bought 3 Rheem tankless water heaters at the same time, mom's house, brother's house and my house. All 3 are running very quiet, installed by ourselves.

It was easy to install if you follow all directions and know what your doing some what when it comes to running water lines

Takes a tad longer than a tank to deliver hot water, but once it does, it doesn't stop. You do not run out..for instant hot water you need to put a recirculator into the loop...more money like a grand or more for one with installation. Caught me off guard that a tankless goes out in 12 to 15 years just like a tank...get a warranty provider like American Home Shield for that event as well as the entire house. Overall, I'm happy with it...$3,300.00 to have it installed...a flat rate, all inclusive with half-off of old tank. Mines a gas unit.

If you want to learn how to install this unit, watch my youtube series on this. Here is a link to the playlist. https://www.youtube.com/playlist?list=PLq6fTBrWkVi5cYf5IibJoypH0eFDq-BGH The is not for the average DIY'er. You need to know all aspects of plumbing like working with gas and water lines (and codes for your area), PVC piping, siding and exterior work for the venting, and even maybe some framing (I had to build a wall to hang it). NOTE: The Quick Install instructions have conflicting data from the full instructions with regard to venting. Watch my Part 5 video on the venting and read page 34-35 on the full install instructions. I do like that it included the outside vent plate. Also, you REALLY should by the Watts Tankless Water Heater Valve Kit with this unit in order to do maintenance (descaling). https://www.homedepot.com/p/Watts-3-4-in-Lead-Free-Copper-Tankless-Water-Heater-Valve-Installation-Kit-0100156/205078015 I have only had it one month and so far, so good.

We have only had this unit for about a month. It comes from the factory with a preset limit of 120F. If you hold the up arrow for about 5 seconds it opens up the range to 140F. After changing that setting change, everything works very well. Constant hot water, and plenty of it for multiple showers at a time
