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

        Comments about Electric Tankless Water Heater - 13 kW:

        I'm cautiously optimistic. The unit wasn't very reliable out of the box. IT worked for a day and then wouldn't turn on at all when the hot water was turned on. I investigated and found that the flow sensor switch was not ideally positioned - it was located too far away from the magnetic plunger to reliably engage and activate the heating circuit. I poured over the few documents available online, contacted CPO and Rheem and they were unfortunately of little help other than - "we'll replace it for you". I wanted to know why it failed. From the documents, there appear to be different versions of mounting hole locations for the flow sensor switch. I tried repositioning it with the other hole on the switch board and it worked fine. I contacted Rheem to see if this was acceptable or would void the warranty. Their tech tried to be helpful but couldn't tell me. He basically said," I don't know since I'm looking at the same photos you are." I asked if he could communicate with the design engineer. He said that he didn't have access to those individuals - NOT VERY CONFIDENCE INSPIRING. In any case, the new position worked fine for a day or two but then started intermittently turning on the heat for a brief moment when the hot water was not turned on - NOT GOOD. I then drilled a new hole between the two existing holes on the switch mounting board and repositioned it. It has been working fine since (3 weeks).
        As to performance, understand that you can take showers with it even with cold inlet water temperatures ( I live in New England). But that is at the limit of its capacity. You might need to throttle back flow volume to get a "hot" shower - otherwise it can be luke warm when inlet water temperature is as icy as it is here.

        I would say that this product is recommended with one important reservation - as long as Rheem and CPO are willing to stand by their product which they appear to be. If they are willing to warranty a defective product for the full 10 years - not just the heat exchanger part - then this is a no brainer. You will not find a better value or more intelligent choice when it comes to providing hot water for a small home. IT IS THAT GOOD!
