    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.

NO WAY. I put it on a single faucet and it barely handles that!

I have a twin 30 amp breaker on my 220v service to my old water heater. Is this a 60 amp service or only 30?

My old tanked water heater used $420 in energy per year! I am looking at tank less but am not sure my current wiring will handle the load of this unit. Not sure if a twin 30 amp is referred to as a 30 or a 60 amp. Thanks in advance.
Asked by: Ray
You need to replace the breaker for a 40 Amp and also change the wiring.

Correct model number?

Is this the same model number as the RTE-9 listed on Rheems website? Thank you
Asked by: drog55chev
It appears even Rheem doesn't know their own products. My question was very specific. Is the RETE-9 and the RTE-9 the same. The answer is no after doing a little more research on my part. The RETE is an EcoSense while the other is not. I couldn't find the RETE-9 on Rheem's website either. The difference is minute but there is a difference without going into the specifics. I bought the RTE-9 off Amazon but haven't hooked it up yet.

Should be good for a cottage with 1shower ?

Asked by: Garster
yes--this is why we purchased it and it works well if no other hot water is being used. Our incoming water temp was mid-40s.

RETE-9 - 9kW 1.37 GPM Point of Use Tankless Electric Water Heater is rated 3.9 out of 5 by 65.
Rated 5 out of 5 by from 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.

Flow sensor appears to be sticking as red lights remain lit after water flow is shut off. This causes the unit to overheat and trip the protective shut down switch. Before this, I was very happy with the unit. I see that Rheem no longer sells this line of electric tankless. They have switched to a line made by another company that Rheem has purchased. I need to find out if the warranty will be honored as it is less than a year old.

Rated 5 out of 5 by from 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!

The RETE-13 was a good product so naturally they quit making it. This thing is on a single faucet in a shop bathroom and you have to leave the faucet about 1/2 closed to get water warm enough to wash hands.
