Customer Questions & Answers


Does this water heater need to be plugged into an electrical ooutlet?
Asked by: Bob
I said it does not require an electrical connection because it is gas. While that is true as confirmed by Rheem, it seems to be a little misleading. In order for all functions to work, yes it does. The electrical connection is not for the water heater to function, it is for the wireless control to function. That said a 100v connection on minimal amps would suffice as a wireless control uses hardly anything. Usually a gas water heater is located next to the furnace so they can share the same flue pipe. We all know a gas furnace does need 110v for the fan to work, and an additional outlet can be had from that connection easily, so it isn't a big deal since the amperage draw is so minimal. Hope that clears it up. The wifi is not a necessary part of the water heaters function.

Does this Rheem model require a 110v hook up?

I need to know if I need to provide an electrical outlet near the water heater location.
Asked by: Rich
Yes, for the electronic flue dampening system that sits on top of the tank in a black box.

How is it packaged during puck up. Can it be loaded on its side?

Asked by: gewii
It comes packaged in a sturdy box container. And yes, it can be laid on its side. This unit weighs close 160 lbs. so it's a two man job to move the unit carefully. You do not want to risk banging the water heater too much or not at all if possible.

Performance Platinum 50 Gal. Tall 12 Year 40,000 BTU ENERGY STAR Natural Gas Water Heater is rated 4.3 out of 5 by 522.
Rated 1 out of 5 by from WORST Experience EVER! 18 months ago, we bought a water heater from Home Depot, paid for a professional installation, and purchased the extended warranty. My water heater went out Sunday night (September 25th, 2016). It’s impossible to keep absolutely precise numbers, but I estimate that since then, I have: • Chronicled 20 pages of notes. • Made 10 phone calls per day. • Spent 30 hours on the phone. • Spent over 10 hours on hold. • Talked to 6 different companies. • Been transferred to someone else over 50 times. • Waited 4 days for 2 sets of parts (none of which solved the problem). • Missed 5 days of work. • Was promised a resolution by numerous individuals. It is now 5 days later it’s Friday, September 30, 2016 at 8:59pm and I still don’t have a water heater and probably won’t get one until Monday at the earliest. I have not gotten a shower in 5 days, I’m running out of clothes to wear, and have a full dishwasher and a sink overflowing with dirty dishes. I have never before been the victim of such a disappointing, frustrating, infuriating customer lack-of-service experience. I expected much better from Home Depot and its affiliates.

I just had this installed today, so I really cannot say much on how much it runs. However, it was pointed out to me by my installer that if the power goes out, I have to go out to physically turn off the unit and then turn it back on. Every single time the power surges. No longer can I just leave it alone and have it run no matter what. When the power goes out... the pilot light goes out. It's a bit inconvenient and can lead to times when I won't have hot water. Something that I would've avoided had I realized this before I bought this unit.

There are 3 adults in our family that enjoy long, hot showers and this tank doesn't disappoint. Plus water temperature is constant unlike our previous tank which was about 20 years old and just didn't do the job anymore. Another plus is this unit doesn't have a pilot that stays lit all the time. Only fires when you use hot water. The dimensions are exact which allowed us to increase the capacity from 38 gallons to 50 gallons in the same space. definitely recommend Rheem and this Energy Star model.

Rated 1 out of 5 by from Do not purchase We do not recommend purchasing any product made by rheem! We purchased this hot water heater and it did not work. We contacted the company who informed us that they would overnight the part. We waited and waited and eventually (after three different phone calls) found out that the part was unavailable! Our contractor had to reinstall our old tank while we returned this one and bought a new tank (of a different brand). The company refused to compensate us for the contractor cost. We filed a complaint with the BBB and they were unable to help. Rheem does not value its customers and we will never purchase another product that they make. We recommend you steer clear. Also- we recommend Bradford White brand- no problems at all and cheaper!

Rated 1 out of 5 by from When to say no to technology We have had nothing but problems with this water heater. It turns off and on so we don't know if we will have hot water or not. The machine gave us a variety of codes/ none of which solved the problem. The manufacture is more than happy to send parts to you and have you fix it. However, after promising to send a tech to our house, they told us if the tech did not find a problem that the bill would be on us. The tech. never called or showed. We believe there is a problem with the heater coupler and the computer on the water heater, which will not recognize when its time to heat. We are taking it back to Home depot today....

Rated 1 out of 5 by from Not happy so far Purchased on Sept 23 and I am already getting valve failure notices. I replaced a 20 year old unit that was working fine to go to a brand new that fails. I hope to get a plumbing contractor to my home soon and hope the warranty goes smoothly.

I bought this 50 gallon Rheem Performance Platinum Series Water Heater at HD, using my veterans discount plus an 11% store issued rebate. Yippee! Picked it up at the store with my teenage son and used it as a teaching opportunity. Yippee again! We used Sharkbite hoses, which eliminated the opportunity to teach him about sweating fittings, but was a HECK of a LOT easier! It really is shocking how easy they are to use... Everything about this installation went extremely well. From the physical connections to plugging it in and starting it. Easy, easy, easy! (I worry my son may thing every project is like this...) I was concerned with setting up the EcoNet adaptor, which was included in the box from HD. I would never have paid separately for what seems such a silly little thing... (An app for a water heater?! What the...) As it turned out, it worked perfectly smoothly from unboxing, to plugging it in, to mounting it, connecting it to my network, downloading the app, entering the obligatory e-mail address and then adjusting the temp with the app. I've read a lot of complaints about difficulty in setting it up, but I had none. Just lucky, or maybe it's that I tend to follow instructions to the letter. Whatever the reason, I'm satisfied with setting it up. The app itself is rather limited, as has been stated. It basically lets you set the temperature and place the water heater in vacation mode. Given that I never once adjusted any previous water heater I've owned after initially setting them up, I can't envision I'll have much need to make adjustments via an app with this one. But, it's there. Maybe I'll mess with the family a little while I'm on the road? It's a water heater. It installed and setup very easily. The water is hot. All good!

Disclosure: I'm a retired mechanical engineer who worked as an "Energy Engineer" for a U.S. government agency. When it came time to replace two 16-year old water heaters located in my attic (that's Texas for you!) I got several quotes from plumbing contractors to both supply and install water heaters. The cost for them to install two 12-year warranty (non-Energy Star) Rheem units was very expensive. To bring them up from an 8-year to a 12-year warranty, they added the price of a magnesium anode kit from Rheem to the contractor-grade 8-year units. So, I bought two of these from Home Depot, got TWO $200 rebates from my natural gas provider (since they are Energy Star rated) and asked for bids on the installation of water heaters that I supplied. Not all plumbing companies will install units they don't provide, but I found an excellent one that would. Several of them told me that they couldn't sell me their contractor version (the exact same unit with a different model number) of this Energy Star water heater for the price I got it for from Home Depot. The bottom line is that I saved about $1,000 and got Energy Star units instead of 12-year conventional units. There's one main difference that makes this an Energy Star unit (only marginally increases the efficiency vs. non-Energy Star): It has a motorized damper which, after the burner turns off, isolates the flue duct (open to the cold air outside) from the hot heat exchanger of the unit. This traps the heat inside the unit and boosts the efficiency. Beware that this motorized damper requires a 120V electrical outlet near the location of the water heater. Most water heaters don't need an electrical supply. This unit also has electronic ignition and an easily adjustable water output temperature. I haven't added a Wifi adapter and may not in the future, but I'm glad it's Wifi ready and overall I'm very pleased with this water heater!
