Rated 5.0 out of 5.0 by HK Excellent product
Very happy with this as my choice of tankless water heater. Easy to install and operate. Perfect for my utility sink in my shop. When turned up, water will get scolding hot if you turn faucet on low flow. The faster the flow the lower the temp. That's how these heaters work. You can get pretty hot water with a decent flow with this model.

Rated 4.0 out of 5.0 by Jim Far better than most other point of use water heaters.
So far the unit has done what I need it to do. I was not able to run a new hot water line to the sink that it now serves and this unit fit the bill. I t was not difficult to install as I was simply replacing another point of use water heater which failed after only a few months. The one I replaced was a sealed plastic unit and did not have any temp. settings, the new unit has a temp setting which gives you flexibility as water supply temps in this region can change with the seasons. This new unit also has copper and brass internal parts, cant go wrong with this type of construction. Its only been in use for about one month yet I believe I made the right choice.

Rated 5.0 out of 5.0 by KinSC It exceeded my expectations
I had some concerns if the water coming out of the kitchen tap would be hot enough but it was hot enough to be uncomfortable. I didn't measure temperatures but the incoming water is the coldest this time of year so it should be piping hot in summer.

Rated 5.0 out of 5.0 by Bob very satisfied
I was concerned, as previous reviews of this heater were mixed, and the chief complaint was that it does not produce hot enough water. I installed it for an outdoor shower with a 1.5 GPM shower head and have been very happy with the result. With the heater set at about 80%, the shower water is 105F and I have to mix in a little cold water for comfort. Ground water here is about 68F, which helps significantly, and the 1.5 GPM shower head is key. It takes about 10 seconds to get the water up to temp, and after that it remains consistently hot.

Rated 5.0 out of 5.0 by Glennie Installed quickly. Hot water in a few seconds!!! Love it.
Hot water in seconds, now the dishwasher works much better. Only problem was pulling a 220 volt line through the basement ceiling across the house, then drilling through a 6-inch concrete floor. But this was not a problem of the heater.

Rated 4.0 out of 5.0 by Stratcat Very useable hot water system for small home.
The first unit fail in a week, after I contacted Rheem tech support and being transfered around a couple of times I finally spoke with a very helpful person who had me remove to cover and check a reset button then ask if I had a multimeter and had me test the input voltage and heater resistances which were ok. He then determined the controller had failed and issued a return authorization. After returning the unit to my local Home Depot for credit we reordered on line, and the new unit arrived and worked fine.
It provides adequate warm water for light use such as sinks and a low flow shower, but must be set to max output for "hot" water. The unit takes up very little space uses little power and works well at our lake cabin. Installation requires copper pipe at the heater and SharkBite fittings work best.

Rated 4.0 out of 5.0 by MetaLark Update to my previous review
I previously published a 5-star review of the RETE-9, but in the meantime the product failed for me. I still consider it worth buying, because it performed flawlessly for six years. And in fact, when it failed, I ordered another just like it as a replacement. But if I had it to do over again, I would have ordered the RETE-13 to begin with; its customer ratings are awesome at this point, and it costs only a few dollars more. The main reason I reordered the RETE-9 was that I'd have needed larger wiring for the RETE-13. And at my age (79) this replacement is likely to outlast me anyway.
This model has a 10-year warranty, but I hadn't kept my receipt, so didn't bother with applying for compensation. (Lesson: keep your receipt.)

I have the heater on the deep sink in my shop. Works great for washing hands and giving my dog a bath.
