SOURCE: TRYING TO REPLACE MY OLD RHEEM WATER HEATER MODEL

I would say your water heater is from the fury series; new model number 82V52-2. I've included a link with my solution that you should take a look at. You could also look at water heaters of a different brand if this one isn't available in your area. Kenmore, GE, and Hotpoint are all very good brands of water heaters.

SOURCE: Rheem water heater model #82V661

You have 240volt electric water heater
Check both elements for leaking.
Check top of tank for leaking pipes.

If water heater is leaking from side of tank, then tank is rusted out and could rupture.
This tank must be replaced.
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html

My friend welded his tank to get more life out of tank, but he assumed the risk.

Hot water heaters are under pressure from heated water which expands.
If tank ruptures, water will flood out of tank and water will run until shut-off is turned OFF.
This causes major damage inside home.

Protect yourself first, and then let's talk more.
1) Turn off water at shut off located on cold water line above tank.
2) Turn off power to water heater:
Gas heater, rotate valve to 'pilot' so pilot is lit but burner does not turn ON.
Electric heater, turn off circuit breaker.
3) Open tub spout on hot side and let run a bit to relieve pressure.
4) Now your property is safe.

You can limp along with failed heater if leak is slow.
Turn heater ON when you need hot water.
Typical Gas heater makes 41 gallons hot water per hour.
Typical Electric heater makes 21 gallons hot water.
Shower uses 5-9 gallons hot water, bath uses 12-14 gallons hot water.

If you are going to install heater yourself:
Look at label on side of old tank to identify size and particulars.
I buy ordinary heaters from Lowes and Home Depot and always buy scratch-n-dent models when possible, because superficial damage to outer tank does not lower lifespan of heaters I have installed.
Buy same size heater if it worked fine before.
Buy new flexible water connectors.
Set water heater in drip pan.
Offer 10% less than price shown. Make them deal with you. Shop Ace hardware, Lowes, Home Depot. Kick the tires since you have a bit of time.

I know you have electric heater, but many folks read these answers, so I include info on gas too.
#1 rule) tankless heaters are a rich-man's toy, because tankless will never pay you back, and will become major money pit if you encounter 1 repair. Electric tankless heaters require larger electric service box. Gas tankless require larger gas line (larger gas line, more gas consumption, bigger bill unless you cut consumption)
2) How to install gas heater:
http://waterheatertimer.org/How-to-replace-gas-water-heater.html
3) How to install electric heater:
Read link above because many of same steps apply to electric.
The difference with electric, is turn off power, disconnect wires, and reconnect wires exactly like before. Set electric heater directly on insulated surface like dense blue styrafoam. Cut styrafoam in circle so it fits inside dip pan. Wrap entire electric heater with insulation blanket, except don't cover TP valve.
4) Connect bare copper jumper wire between hot and cold pipes to prevent stray current corrosion which will shorten life of tank. Make sure cold water line is grounded.

How to get a warenty replacement unit


First, you'll need to gather all pertinent info- including model / serial number and any paperwork indicating date of installation or purchase.

Next, go to Rheem's website. There is help there to assist you to locate your heater's model and serial number if you are unable to / unsure of where to find it. If you live in the U.S. and have the model / serial number data, you can go to the Homeowners Resource Center page and click "Water Heating Product Warranty Verification" link inside the Warranty Section. If you live in Canada, you cannot use the online verification and should call 800 263 8342 instead.

I hope this helps & good luck!

Rheem water heater flashes seven times ,it is in lock out mode


You have Honeywell electronic gas control valve, and error code is 7 flashes.
Probably you have power vent model.
One manual from different company says: "Reset gas control using on-off button on front of control, replace flammable vapor sensor, replace gas control thermostat.
But with Rheem you also need specific steps: Remove gas burner and look for broken glass vial, and then blow out arrestor screen air intake using compressed air, clean burner parts, check for unobstructed venting, you will need new glass vial from Rheem depending on year and model number of water heater that appears on label on side of unit, or they may not have a repair kit for that model, and you might need a new gas control valve depending on model and how extensive problem was
You have Rheem water heater.http://waterheatertimer.org/How-to-repair-Rheem-FVIR.html

Where is the combustion shutoff system on a Rheem 30 gal moble home hot water heater


Disproportionate number of water heater problems are Rheem-related, yet Rheem is just 1 of 3 major water heater manufacturers.

If you have Rheem tank-type gas water heater, and the combustion shut off has tripped the FV system, then there is a broken glass vial located under the burner.
Rheem does not post service manuals, and they may or may not send the glass vial for replacement. Depending on model which appears on label on side of tank. Year of manufacture are 3rd and 4th digits in serial number.
And they may want you to contact a qualified service technician (plumber)
You will have to replace glass vial, and clean the arrestor screen and clean the combustion parts, check gas pressure, and check venting.
Other companies post service manuals and do not rely on the glass vial.

Where do I find the serial number for a Rheem Stellar gas storage hot water unit


Serial number should be on label on side of tank.
Labels contain information like model number, tank capacity and BTUs
First 4 digits of serial number are date of manufacture: for example 0604 is June 2004
Take photo of label for easy reading and for your records
