    How to Choose Your Rheem EcoSense Tankless Electric

    Choose your application, ie. shower, bath tub or vanity sink-faucet, kitchen sink faucet or washer. See chart below.

    For example: you choose a kitchen sink faucet.


    See application chart below and locate your flow rate. For example: your flow rate is 1.5 gpm.


    On the map, locate the average water temperature in your area.

    For example: your water temperature (in Atlanta) is 55°


    Use the water temperature and flow rate chart to determine the model you need.

    For example: 1.5 gpm flow rate + 55° = RETE 9.

CUSTOMER REVIEWS

Rated 4.1 out of 5 by 31 reviewers.
Rated 5 out of 5 by I love my Rheem RETE-9 ! My son installed this tankless water heater under my bathroom sink about 5 years ago, and it has functioned flawlessly during that time. It gives me plenty of good-and-hot water, delivered very quickly. If I want it scalding hot, I just run the stream a bit slower. A few months after installing it, I asked my son to connect it to the shower that backs up to the same wall. The flow there is a bit slow for my taste, and I have to run the shower full hot in order to get a good water temperature for that higher-volume flow; I'm fairly satisfied with that, but I would recommend a more powerful heater if you want to use it for a shower.

Rated 5 out of 5 by Exactly what I hoped it would be I read some reviews on this product before I bought it and some of those people should be embarrassed of themselves. There is a clear chart showing how to "size" the tankless style water heater for your area. Some of these people are getting this small unit when their ground water is only 50 degrees, what are you seriously expecting to happen. This unit works great for my house. I have a 2 bedroom 2.5 Bath Townhouse in South Florida. I don't need a very strong tankless heater because our ground water is so much warmer than the rest of the country. So this thing works great. If you properly size the unit for you house and location it will work just fine. September 16, 2014
Rated 5 out of 5 by Lovin it! We have a small one bath, two sink cottage which had a huge water heater in my closet taking up space. My brother and friend (who are handy) installed this tankless system. It takes a new heavier wire to the electric box and some new pipe ends. I would hire it done unless you have done a lot of this work before. Installed this tankless is awesome! I have continuos hot water for my shower that stays constant. It is super hot for dish washing. Probably could not wash dishes and someone take a shower at same time on this small system. But it cleared up my closet space and I don't have to pay for heated water sitting around. I love it! April 28, 2013
Rated 4 out of 5 by Good for what it is For a smaller tankless, it is good. It was easy enough to install, but i noticed that it worked better with a 5/8" connector and the 1/2 " was too small. The electrical install was pretty simple, but it does take some space in the box. I have been pleased with the heat produced thus far. I would suggest starting at a trickle and then increasing flow until desired temperature is reached, otherwise it seems to not heat well.. October 28, 2014
Rated 5 out of 5 by Does the job This water heater was easy to install and works well. I added it to my garage sink. It gets sufficiently hot for hand washing, even with a fairly low starting temp in the barely heated garage. Don't expect a hot shower from it, but it's good for a vanity sink December 23, 2014
