How to find your Rheem Water Heater model number?
Most water heaters come equipped with a Rating Plate that includes relevant info such as serial number, model number, manufacturer's name, year and month of productions, etc.
However, the best part is that you won't have to spend hours on end trying to locate the rating plate on your Rheem Water Heater – because the sticker is located on the water heater's exterior. Tankless water heaters generally have the stickers placed on the right-side of the surface.
Rheem Water Heater Instructions
Rheem manufacturers residential and commercial water heaters – which means their water heating product line is rather diverse. However, a typical Rheem water heater manual contains the following categories to make for easy navigation:
- Safety Information: This section includes all the information you should read before installing or using the heater.
- Installation Instructions: As the name suggests, this heading contains details related to installing the water heater. It includes three sub-headings – location, water connections, electrical connections. There's also a handy installation checklist at the end to ensure you've followed all the directions.
- Operating Instructions: This section is divided into two subheadings – safety controls and water temperature. For instance, the manual lists out four easy directions to reset the temperature limiting control.
- Care and Cleaning: Contains directions for draining the water heater, vacation and extended shutdown, and routine preventative maintenance.
- Customer Service: This part includes details and diagrams about replacement parts, cavity insert instructions, and wiring diagrams.
At the very end of the user manual you’ll find detailed steps about how to register your product’s ownership and a small fill-out form for the same purpose.
Rheem Water Heater Troubleshooting
Compared to some of the other user manuals we've compiled on our site, Rheem water heater manuals contain concise troubleshooting tips. However, that's probably because of the obvious safety risks involved in water heater repairs. That's why it's best if you contact a licensed contractor to install and repair any issues you might face. Remember, safety always comes first.
Additionally, you should also note that some manufacturer warranties for water heaters can be voided if the product is not installed by a licensed professional. Make sure to find out if such terms apply to Rheem water heaters before purchase and installation.
The troubleshooting tips section lists out the possible causes and solutions for the following problems:
- Rumbling noise
- Relief valve Pressure producing popping noise or draining
- Rattling noise during periods of water usage
- Not enough or no hot water
- Water is too hot
Types of Rheem Water Heaters
Rheem manufactures and sells a diverse line of cooling and heating products for both commercial and residential use. This line-up includes oil furnaces, 98.7% fuel-efficient (annual) gas furnaces, heat pumps, 20 SEER (Seasonal Energy Efficiency Ratio) air conditioners, and package units. The company also creates indoor air quality (IAQ) products such as UV lamps, humidifiers, and media filters.
As far as residential water heaters are concerned, here are the categories you’ll find on the company website:
- Tankless Water Heaters – these heat water without the need for a storage tank, and this makes them perfect for folks who are short on space in the bathroom.
- Hybrid Water Heaters – pull in hot air into the appliance's evaporator coil to heat water. Also referred to as a heat pump water heater, this device needs a moderate or a warm climate to work efficiently.
- Tank-type Gas Water Heaters – are the most prevalent water heaters because of their low installation and operating cost. These water heaters run on gas and require ample space for setup.
- Tank-type Electric Water Heaters – are pretty much like tank-type gas water heaters in function, except that these heaters run on electricity.
- Specialty Water Heaters – are tank-type water heaters that are powered by solar energy.
About Rheem
Donald and Richard Rheem founded Rheem manufacturing in 1925, but the company started manufacturing water heating products in 1931 after acquiring the John Wood Manufacturing Company of California.
Since then, the company has expanded operations, and now, it manufactures cooling, heating, commercial refrigeration, air quality, and water heating products. As a matter of fact, Rheem happens to be the largest manufacturer of water heating products in all of North America – which is no small feat.
In 2008, the US Department of Energy ranked the company at fifth place in the central AC and heat pump market, and in 2015 Rheem won the most popular water heater title by Builder magazine.

I keep pdf’s of all my appliances. I have a HPWH – AP21681 Rev 03. I don’t see the download for the Rev 03. Only the original publication. Can you supply the updated version, please?

9 year warranty
Will this appliance work as it should if it is out of warranty?
Also there are 4 holes on the top and 2 of them have copper water line pipes, one of them has a power cable going to the wall and the 4th hole has nothing un it, it is just a hole without a plug or a pipe in it. I think that is for the anode, which seems to be totally missing.
Is is safe to use the appliance the way it is set up
Thank you for your time.
