    This heater works really well. One of the previous reviewers complained of lights dimming when it came on. I have noticed no power issues. It takes 10 or 15 seconds longer to get full hot water because it has to heat up from being completely cold. Other than that, I can’t tell any difference from the old tank unit.

    Not much for writing reviews, but feel compelled to do so now. We needed a new water heater, as ours was 20 years old. After much research on on-demand water heaters, we decided to go with the Rheem water heater. Our previous tank was a Rheem and it performed it’s job well for all those years. Installation of the tankless system was time consuming as circuit breakers, wiring, and plumbing supply lines all had to be replaced. The system initially did not work. No hot water and temperature indicator light not illuminating. This is where tech support earns their five stars and the Rheem system subsequently earned it’s five stars. Winston was the tech support guy that helped us through this. He walked us through trouble shooting the product, determined what the problem was and next-day shipped the replacement parts to us. Our home address was not registering for shipping and he was very diligent about finding a way to get us the replacement parts ASAP. Meanwhile, Winston continued to help troubleshoot the problem, even after replacement parts were ordered and on their way. The troubleshooting proved fruitful and we suddenly had HOT hot water in no time flat. To top it off, we were told to keep the already-shipped replacement parts as spare parts in the event of the system not working/needing replacement parts. Can’t thank tech support enough, the on demand hot water heater is out-performing our old tanked system (which we ourselves installed upon building the home) and we love taking SUPER hot showers now.

    Its a great water heater, we have 3 showers, 5 sinks and the dishwasher and it gives us continuous hot water. Also super easy to install thanks to the fact that the instruction manual is very thorough.

    Save money💲Really hot water for as long as you want to shower.Make sure you get the right size for your needs. I bought this model after reading everything I could about tankless waterheater and decided on this one. Perfect for our house.12/25/20 updateHad to go back to a tank. One element went out after another. Then the controller board. Easier and less expensive to go back to the tank.

    Replaced a 50 gallon hot water tank and have not noticed any difference in our hot water. Still waiting for an electric bill to compare costs; but as of now it was the right decision. I did not rate tech support as we have not used that service yet. I would recommend this product.

    So far fantastic. Limitless hot water. Relatively easy installation. Wife thrilled with long showers. Needs a reduced inline from 34 to 12 inch so heater can keep up. Well worth the money.
