Great Product!
Installed in a rental home as replacement for a 40 gal tank heater. It took longer to drain the old heater than to install the RTE-7. My tenants are thrilled with the water heater. Just big enough for a one bedroom, one bath without a washer or dishwasher. Freed up a large amount of space in an already crowded bathroom. Love this product! Perfect for this application or an office.

Very satisfied
Easy installation and works great so far. If used for a shower, you will need a low flow shower head. I used a 1.25 gpm shower head and get a pretty good flow of constant hot water. It depends a lot on the ground water temperature. For faucets, I would recommend a 0.5 gpm nozzle. My ground water is 43 degrees this time of year(February). In warmer weather it should do much better as the ground water temp. will be higher.

Electric Tankless water heater- 7 W
Mostly to wash my hands after working in my shop. It is Quick, and do not have to keep water hot for limited use. It is slower and does not get as hot as my first one. However the first one did not last long. I hope this one does.

Great Little Heater
This is NOT for the do-it-yourself-er. To isntall this unit you must be able to sweat copper pipe. Unless you are very good with this I suggest getting a plumber. It's not hard to install but has copper pipe fittings. It works great but doesn't get as hot as I thought it would. It only gets hot enough to be uncomfortable holding your hand in the running water. I really thought it would deliver scaulding water. It also lowers the water pressure to the sink. I guess it can only put out so much hot water because it is a small unit.
On time and corrrect

Can this product be used in a mobile home?
N/A on Jan 16, 2016
BEST ANSWER: Yes,as long as you have 220 volt capabilities.
Would this be enough for a kitchen sink and a bathroom?
Heather on Apr 29, 2016
BEST ANSWER: Certainly enough for a kitchen and bathroom sink, but not including a
shower or tub. I installed mine as a booster on the kitchen sink but still
have to use a low flow aerator to keep the water really hot until the hot
water from the water heater gets there. Once that happens it's so hot I
have to adjust it a bit cooler. I also use it to preheat the water into the
dishwasher.
what size is good for a family 5 household a 3/2
Leo on Jun 26, 2016
BEST ANSWER: NOT the 7kW unit... I strongly recommend going big or stay home with these tankless units.  If you have 5 people in a 3/2, I would spend the extra money on a RTE18.  In the long run you will be glad you did.  Unless of course, if you like luke warm showers if anyone else is using hot water when you are showering. :).

I presently have a gas hot water heater that works great.
Problem is that it takes about a minute to get hot water to my kitchen sink. I have good crawl space right under that sink. How would it work to put your unit in line with my system right under my sink?
no on Jan 20, 2016
BEST ANSWER: This Rheem unit takes up such little space that it can be installed practically anywhere, including under a sink; even a small one.  I have never used one in line with a hot water heater, however I cannot think of a reason why it would not work.  Here is the down side, however.  This tankless unit does not produce anything approaching "hot" water.  Rather, it produces a nearly instant and essentially limitless supply of luke warm water.  If you have your flow down to about .75 gpm, it produces the best luke warm water, and with flows > about .75, it declines to cool water.  As an example, I measured the cold/in temperature at 2.0 gpm on mine, and it was about 38 degrees.  The "hot" side of the unit measured around 85 degrees, for nearly a 50 degree increase.  However you cannot take a very pleasant shower with 85 degree water...... Hope this helps.  
I own a small apartment building in which there is a coin op laundry. The apartments all have their own utilities,Mao the only reason I have gas service is to run a 40 gallon gas storage water heater. The gas suppliers has multiple minimum charges, regardless of usage, of of $30 per month. I would like to cancel my gas service and install a point of use water heater at the single, standard capacity, washing machine.

Will one of these water heaters do the job?

John
John on Jan 10, 2016
BEST ANSWER: Not to be vague, but the answer is "sort of.".... 
The 7KW Rheem will give you an unlimited supply of luke warm water.  If you are OK with luke warm water, this unit is for you.  If you actually want hot water, this unit will disappoint you.  I have one in a small cabin.  With a 1.5 gpm water saver shower head, and with the water only running 15 feet before reaching the shower (and with no other water running to compete with it), a person can take a very exciting shower at about 90 degrees, but you certainly don't want to loiter.   Same with the bath sink.  On a trickle it sort of gets a little hot.  If you dare to run it at 1/2 to full, it drops back down to the Rheem 7kw comfort zone (i.e., luke warm). 
On a positive note, it is easy to install and takes up virtually no room.  Keep in mind, if you get one, you will to have access to 220. 
Good luck.

DiAnn on May 7, 2015
BEST ANSWER: The Rheem RTE-7 is 240 volts.
would this unit be able supply a one bedroom apt with a kitchen bathroom and washer.
Michael on Apr 9, 2015
BEST ANSWER: No, this electric water heater would be too small for that application. The smallest unit that could recommend is a Rheem model RTE-18. Please note however that these electric water heaters are capable of one (1) application at time. This means you can not run multiple applications at the same time (i.e running a shower and washer simultaneously).
Can this unit be installed on the outside or is it best inside? And can it be run my existing hot water line?

BEST ANSWER: That unit is for indoor use only, and uses a 1/2" water connection.

My main hot water heater is 4 floors below the master bath, requiring me to waste a lot of water waiting for it to get hot. Can you plumb hot water into this unit so I get hot water instantly, but then let my main gas unit take over primary heating duties once the hot water arrives? Or do you HAVE to plumb cold into this unit?
Steve-O on Nov 2, 2014
BEST ANSWER: That unit is designed for incoming cold water only.
this is 100% abrand new unit please let me know before i purchase it

This Limited Warranty does not cover any labor expenses for service, repairs, reinstallation, permits, or removal and disposal of the failed water heater, or defective component part(s). All such expenses are your responsibility. Rheem will pay the transportation costs for an “in-warranty” replacement water heater, or “in-warranty” replacement component part(s), to a convenient delivery point (selected by Rheem) near the place the original water heater, or original component part(s), is located: such as a local Rheem or Ruud water heater distributor.You must pay any local freight charges, including the cost of returning the failed water heater, or defective component part(s) to a convenient shipping location (selected by Rheem): such as a local Rheem or Ruud water heater distributor.

Rheem will not reimburse any party for these, or any other, fees not specifically covered in this Limited Warranty document.

HOW TO OBTAIN WARRANTY CLAIM ASSISTANCE

Any claim for warranty assistance must be made promptly. First, determine if your water heater is “in-warranty” (that is, within the Applicable Warranty Period).You can determine your unit's warranty status by adding its Applicable Warranty Period to its date of installation. However, if you do not have documentary proof of your water heater's date of installation, your unit's warranty status will be based on its date of manufacture. The first four digits of the unit's serial number represent the month and year it was manufactured. Add the Applicable Warranty Period plus ninety (90) days to the date of manufacture to determine whether the water heater is still covered by this Limited Warranty.You may also determine your unit's warranty status by obtaining the complete model number, complete serial number, and date of installation of your water heater and then accessing the “Warranty Verification” information on Rheem Water Heaters' internet website (www.rheem.com) or contacting Rheem Water Heaters' Claims Department (telephone (800) 621-5622) during normal business hours (in the Central Time Zone) to determine if the Applicable Warranty Period has expired. If your water heater is “in-warranty”, contact the plumber, or mechanical contractor, that installed it for assistance with the warranty repairs, or replacement, required.You may also select a plumber, or mechanical contractor, from your local Yellow Pages to assist you. Rheem Water Heaters' Technical Service personnel are available to assist you (by telephone at (800) 432-8373 or via e-mail at techserv@rheem.com) in obtaining “in-warranty” service or to answer your questions about the operation or repair of your water heater during normal business hours (in the Central Time Zone). Be prepared to provide the plumber, mechanical contractor, or Rheem Technical Service person you call with the complete model number, the complete serial number, and the date of installation of your water heater in addition to an explanation of your water heater problem. If an exact replacement is not available, Rheem will provide you with the current model of your water heater, or component part(s), or a replacement unit with comparable operating features. If government regulations or industry certification or similar standards require the replacement water heater, or replacement component part(s), to have features not found in the defective water heater, or the defective component part(s), you will be charged for the difference in price represented by those required features. If you pay the price difference for those required features and/or to upgrade the size and/or other features available on a replacement new water heater, you will also receive a complete new Limited Warranty (with the full Applicable Warranty Periods) for the replacement new water heater. Rheem reserves the right to inspect, or require the return of, the failed water heater or the defective component part(s). Each “in-warranty” failure water heater must be made available to Rheem (with the rating label and all the component parts intact) in exchange for the replacement water heater. Each defective “in-warranty” component part to be replaced must be returned to Rheem in exchange for the replacement component part. Warranty compensation is subject to validation of “in-warranty” coverage by Rheem Claims Department personnel.

  • To obtain warranty compensation for an “in-warranty” water heater failure, you must provide Rheem with: (at Rheem's option) either the failed water heater (with the rating label and all the component parts intact) or the complete original rating label (photocopies are not acceptable) removed from the failed water heater; the complete model number and the complete serial number of the Rheem or Ruud water heater that replaced the failed unit; and the date the original water heater failed.You may also be required to provide documentary proof of the failed water heater's date of installation to establish its “in-warranty” status.
  • To receive warranty compensation for an “in-warranty” defective component part, you must provide Rheem with: the defective component part; the complete model number and the complete serial number of the Rheem or Ruud water heater from which the defective component part was removed; and the date the defective component part failed.You may also be required to provide documentary proof of the date of installation of the Rheem or Ruud water heater from which the defective part was removed — or the date of purchase of the part (if it was purchased separately) — to establish the “in-warranty” status of the defective component part.
Warranty claim documentation should be mailed promptly to
