    Really Saves Energy
    Had this for about 5 months. Worked great then the flammable vapor detector failed after about 3 months. Rheem sent a new one out right away at no cost to me. Installed new detector and again working great. Rheem customer service line was very helpful in diagnosing the problem and sending out the replacement part. Would have given it 5 stars except for this problem. Noticeable energy savings compared to the 14 year old smaller capacity unit it replaced.

    Just Finished Installation
    I just finished the incredibly easy installation, total time of install was about an hour. Pilot flame was very easy to ignite (sure beats using matches). I have warm water after about 30 min. of use. I am extremely pleased with our new purchase. After install and the initial start of the burner I sat down and registered the Water heater online which took about 3 Minutes.

    Vapor sensor failure
    I bought 8 months ago. It is definitely an upgrade from our old one, as it puts out a lot more hot water. It seems like it turns on (starts heating water) within a minute of using hot water from a faucet. One disappointing thing was that the vapor sensor failed after 3 months. The result was no hot water. Rheem sent a new one, but recommended that pet food, kitty litter, and cleaning chemicals be removed from the utility room. That was not a practical recommendation, so I may just have to ... read more replace this sensor every so often.

    No electrical power needed.
    I wish all water heater comes with adjustable legs so that it can be easier when installing it on sloped ground just like clothes washer does.

    The real brand is worth the money.
    We did get our rebate in the mail yesterday. Home Depot gave us 11% rebate to match Menards. Net result is 10.00 less than the off brand with bad reviews. This water heater is a 5 all day. Thank you Home Depot for nailing it for us yet again

    Bought mine on sale last year for a low sale price of $239. at local HD. Just installed 2 days ago. and works 100% better than old heater. Extremly quiet and simple to light burner with push of button. All connections matched except T.P. outlet port was two inches taller. No problem, 2 inch copper pipe and JB weld with copper fittings. Works beautifull! Saved $1200 labor cost. other than hiring plumbers. Check out the DIY videos on you tube,wealth of info on installation and maintenance.

    It does it's job
    It's a water heater. The price was fair for the heater. The price to install one with the Home Depot contractor was a shock to the checkbook. The billing process with the contractor was not good. Their communication was non existent. The guy who came out and installed was very professional and did a great job.

    fired right up at the first try
    Did the installation myself since the one day installation service was not available in my area and the plumber wanted $500.00 for it.I had a few curve balls but not for the water heater. Quality seems great, just watch out for the lower mesh section of the outside shell as it bends easily just by putting the weight on one side of the base. Value is excellent.

    Very pleased with the purchase of Rheem 40 gal gas water heater. Product is super quiet, perfect fit (no add'l cutting was req'd), no leaks, extremely hot water, cost effective (lowered gas bill). I highly recommend this this outstanding product. I can't believe just how quiet my basement is now. Thanks Rheem

    Easy install, good performance
    Installed and set up with little effort. I have it set at 1/3 of max temp and it is much hotter than my old heater set to 100%. Haven't run out of hot water yet. Will buy again and recommend it.

    Reheem Water heaters
    I purchased the 40 gal Gas 4 years ago and recently the pilot light would not stay lit. It turns out that the Pilot assembly which is covered under the warranty for parts by GE has a high failure rate. Cost to install the new part runs around $160.00 other then the failure rate of the pilot light this tank is a good buy. Note Reheem makes this tank and most other brands i.e. Lowe's etc

    Rheem Quality
    Very pleased with this water heater. Ordered over the 'net, and picked up in store. I like the convenience of doing the product research in the comfort of my home and taking as long as necessary to ensure I get the product I need. When I arrived at the store, the item was waiting for pickup at the customer service counter - and since it was pre-paid, I was in and out of the store quickly. Self-installed, and it's working very well so far. The only thing wrong with this purchase was that the ... read more water heater didn't come with any instructions nor paperwork. I wondered if it was lost somewhere along the way.

    Hot water heater
    I will be able to tell you more in a few years, but it looks really good since I installed it. It was easy to install. I had no problems. At the Home Depot store the employees were eager to load it for me. I am 76 and not as strong as i used to be. It was boxed very well and I was able to slide it down the stairs with ease. The hookup was easy. Every thing fit. It was easy to start as it has an elect. start button for ignition. (no more matches). The water temperature is easy to see and it has a ... read more light indicating operational condition so you know everthing is working as it should. A great improvement!

    water heater
    The water heater is great, and Ez to install. But Home Depot really, go to check out and all there credit and check verified system are down, cash only or they have to call the bank, on a sunny Saturday afternoon. Then 2 weeks later I went to customer service at a different store and they can't find my order because 1800homedepot was down. You really need to work on your IT department

    Great price, works perfectly
    It was super easy to install, as soon as we got the gas hooked up and tested it lit very easy. No problem heating the water, works a lot faster than my old heater.

    Simple Install
    My 20 year old water heater decided to quit the day we had guests arriving. Left for Home Depot at 8:30AM to get a new gas water heater, my wife was taking a HOT shower at 11:30AM. The boxed unit weighed 120 pounds but the box had plenty of hand holes which made sliding it down the basement stairs very easy. Unit unpacked very easily. Used sharkbite connecters and flexible gas line to adapt to the old configuration. Pilot light lit on the second attempt. This was my first water heater install ... read more but I am not unfamiliar with plumbing and was so easy, my wife could have done it with me coaching.

    Easy Installation - great price
    Was quoted a price for water heater and install at over $1100.00. I bought and installed myself for about $450.00 total which included the water heater and installation kit with some other CPVC pieces and glue. Longest part of the whole process was removing the old water heater (draining, disconnecting, etc.). Several videos available online to assist you .

    Really Good Product
    This unit replaced a 20yr old tank. After 6 months couldn't be happier. Still had hot water in shower after my 2 kids showered and wife ran the dishwasher. Alot of hot water and the temperature is at one of the lowest settings. Putting one in at my inlaws tomorrow.

    Replacement water heater
    This water heater was an exact fit replacement for a world pool 40 gal. Took under an hour and a half to do the swap. Initial start up was simple and well explained. It did take over two hours for first full tank of hot water, but has performed flawlessly since. Burner makes less than half the noise of old water heater. Have not had installed long enough to compare gas usage.

    It works!
    Bought at the Taylor store check out was clean and easy the cashier gave me my veterans discount which is appreciated as this is the only way I shop. I asked for help loading and got it in my truck with no problems. Now once I installed and the wife and kids are taking hot showers we are all happy. Thanks Home Depot!

    Water Heater
    Not sure what else it is supposed to do besides make hot water. Although, it does have a little blinking blue light which is kind'a cool. It makes hot water just fine. Go figure!
