Rheem Water Heater Warranty

Every Rheem water heater comes with a Certificate of Limited Warranty that tells you the details of the product warranty. You can also register your product to get more information about the warranty and learn about options for an extended warranty. The Rheem water heater warranty covers a lot of things, and different models have different levels of coverage.

Rheem makes more water heaters than any other company in North America. The company was started in Emeryville, California, in 1925. It has won awards for its new product designs and cutting-edge innovations.

In this post, we look at the details of a Rheem water heater warranty to help you understand what it covers, how long the warranty period is, and how to make a claim.

How to check if my Rheem water heater is under warranty?

To check if your Rheem water heater is under warranty, you will need to locate the model and serial number of the unit, and then contact Rheem customer service. Here are the steps to follow:

  1. Locate the model and serial number of your Rheem water heater. This information can typically be found on a label on the side of the unit. The model and serial number are usually a combination of letters and numbers.
  2. Once you have the model and serial number, visit the Rheem website or call Rheem customer service to inquire about the warranty status of your water heater. You will be asked to provide this information, as well as proof of purchase, such as a receipt or invoice.
  3. Rheem customer service will be able to tell you if your water heater is still under warranty, and if so, the specific terms and length of the warranty.

It’s important to note that if you have made any modifications to your Rheem water heater or had it serviced by someone who is not authorized by Rheem, the warranty may be voided. If this is the case, you may not be eligible for warranty service.

Rheem Water Heater Warranty Registration

By registering your Rheem water heater, you can use the warranty benefits that come with them, choose to extend the warranty coverage, and use other helpful Rheem support services. The process of registering must be done within 60 days of the first installation.

Product registration is important because it tells both Rheem and the customer how long the warranty lasts. Once the product has been properly documented, you will know exactly how long your Rheem water heater is covered.

To finish the process of Rheem water heater warranty registration, you need to provide:

  1. The unit’s serial numbers.
  2. The unit’s model number.
  3. The installation date.
  4. Your name, email, and where you live.
  5. The contractor’s name, address, and phone number.

If you have already registered your Rheem water heater and want to check the terms and coverage of your warranty, simply go to their official website. For verification, you need the Rheem serial number.

How long are Rheem water heater warranty?

If your Rheem water heater is fairly new, it probably comes with a 6-year warranty. For older models, the warranty could be for eight, ten, or twelve years. Here’s what you can expect from the manufacturer for its gas, electric, and tankless water heater units.

Most of the time, you can buy an extension if your warranty has run out. This addition will come with a kit that will need to be put together by a plumber. This kit has replacements for some of the things that tend to rust the most, like the anode.

Rheem also has a ProtectionPlus plan that gives you an extra 4-years of coverage on your warranty.

What is covered by the Rheem warranty?

The Rheem warranty covers any problem with the way it was made or with the materials. During the warranty period, Rheem will replace or fix any parts of the unit that don’t work because of these issues.

It’s important to know that Rheem’s warranties only cover parts, not labor. Most of the time, the warranty on labor only lasts for one year. That means you’ll have to pay for the work and probably also a fee for processing the warranty.

Here are some conditions that a Rheem water heater warranty doesn’t cover:

  • Failures caused by accidents, abuse, or bad installation of the unit.
  • Equipment that Rheem has not approved.
  • Accessories that are not made by the manufacturer but are made by a third party

How do I claim my Rheem water heater warranty?

To make a claim on a Rheem water heater, you need to talk to the installer or distributor right away about a problem. Or, you can make a call to Rheem Technical Service at 1-800-432-8373 if you want to file a warranty claim for a water heater.


The Better Business Bureau (BBB) gives Rheem an A+ rating right now, and the company has been known in the industry for a long time as a reliable water heater brand. Since Rheem has been around for so long, customers have both good and bad things to say about the company.

Even though a Rheem water heater warranty will cover you for a short time, the warranty from the manufacturer will eventually run out, leaving you without coverage. Failure of a water heater can cost thousands of dollars, and if you don’t fix or replace important parts that are broken, it can cause even bigger problems in the future.
