    Pleased with this product
    I was pleased Home Depot carries this brand as I getting more skeptical of the big name brands as the years go by. I have seen this name in commercial installations and will now get to experience the brand first hand. The water heater installed without any issues as a replacement for an older and broken 10 year old unit. Once I had every thing connected and filled there was absolutely no issues lighting the pilot or getting water up to temp after about 1/2 hour. I have been inspecting it daily ... read more and there are no leaks. I think I'll be very happy about this purchase decision. Only regret is I would have liked to explore new on-demand technology but needed hot water in my house that day.

    Rheem Performance Plus 50 gallon water heater
    My brother and I installed this in about 5 hours on a Saturday, instead of using the shark bite Quick Connect lines we soldered the lines in, were two old guys we went old school. The Shark Bite Quick connect lines would have been easier and would have saved a lot of time. We're old school though. After the installation connected the gas line & opened the valve, turned the knob to pilot hit the button Presto magic we had hot water running within an hour. Saved around $800 from the installation ... read more quotes I had received.

    Installation was a breeze
    Installed on copper water lines. Home Depot associate recommended their Shark Bite fittings instead of the 3/4 copper pipe and associated fittings I had in my cart. All said and done, the shark bite fittings were cheaper than the copper and the installation quite literally took 10 minutes. Cut the water lines, push the Shark Bites onto the copper pipes. Move the gas line over to the new unit. Done. Easiest install ever. Pilot light has a piezo igniter on it, so it's a snap to light. Had hot ... read more water in no time. Even got a nice rebate from the gas company. Couldn't have been any more painless.

    Reheem Perfomance 40 Gal Tall ..Performs !
    Yesterday morning I purchased this water heater without any reservations. I installed it myself & a buddy. We took a long time to get my old 20yr old heater, drained, disconnected, and removed. We installed the Reheem with a lot of tweeking ( cutting/sodering) but eventually it was all connected, pilot light igniting system worked flawlessly. I am extremely pleased with this heater, the water is hot! My wife is happy, I'm happy. Thank you Home Depot & thank you Reheem !!

    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

    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.

    Despite mixed reviews, I have been very pleased. I was concerned about the now-so-great reviews, but the good reviews were great. My friend who installed it highly recommended it, so since the price was right I gave the go-ahead. So glad I did, it has been dependable from the start. Installation was a little rough, he had to make a couple of trips back to the store where he got it, but once he was completely through it worked perfectly from day one.

    Very efficient and quiet - terrific warranty!
    We bought this about 6 months ago, after our previous water heater (a different brand) began leaking just a couple of weeks before the 6-year warranty expired. The kicker is that the prior brand's replacement unit only carries the remainder of the initial warranty. Obviously I wasn't going to make that mistake again. After reading many online reviews and reports, I decided to go with this Rheem model. The warranty and terms are terrific! The unit is very efficient, quiet, and extremely simple ... read more to adjust. Based on our experiences so far, I'd definitely recommend Rheem!

    Actually special ordered RHE50P (LP version)
    Installation cost including adding an expansion tank and metal base pan was 600.00. (Westminster, MD). We are only in the first week but for a power vent his is dead quiet compared to my older State Select. Bought over a tankless as contractor said they were not yet ready for prime time and not what many expected as far as "low maintenance". He also said better value and more reliable than AO Smith Vertex. One opinion of course but I thought I would share.

    Lots of hot water, and fast.
    Bought this from Home Depot's website (not stocked in any local stores), but had a different contractor install it, since the one HD uses wanted to charge me more for the install (which involved relocating the new unit about 3 feet away from the original) than the unit cost. I saved about $800 by using a different installer and buying most of the parts they needed. It took 2 guys about 5 hours to get the plumbing moved and hooked up, and to get the venting run out the side of the house. Keep in ... read more mind that this unit needs either a concentric termination kit, which makes a 5-1/2 inch hole in your roof or wall, or two separate 2- or 3-inch vent pipes. I already had one 3-inch vent from the original water heater, so I ended up running another alongside it. This unit was an upgrade from a standard 40-gallon unit. Once it was fired up, I had hot water within 45 minutes. The exhaust fan is very quiet. Since the combustion air is drawn from outside, and there is no pilot, there is virtually no chance of a CO leak. The heater is very energy efficient; it has an energy efficiency rating equal to that of many tankless units. I am very happy with this water heater, and look forward to lower gas bills every month.

    Excellent high efficiency water heater
    I installed this water heater about a month ago and it's been great so far. I'm an advanced DIYer and I found the installation to be relatively straight forward (read the install instructions first though). It heats water well and has been efficient so far. I used the Rheem SP20286 external vent kit when I put the exhaust and intake lines out. Also be sure to have a place for the condensate can drain to --I have a floor drain that's conveniently close to the water heater. Overall I'm very happy ... read more with this product and glad I installed it myself.

    Just replaced original 20 yr old Rheem that performed flawlessly until eventual inevitable failure from age fatigue. This new one is much quieter, heats very effectively on medium heat setting, installed without issue, and fired up on initial attempt. It's only been in use for 2 days so I'm unable to comment on longevity but the water quality (odor, pressure, temperature) is much improved.

    This hot water heater replaced my 20 year old one. Was leary on brand due to some negative reviews but I had several large gift cards for Home Depot. Been about a month and seems to give an endless amount of hot water. Hopefully it'll last 20 yrs like my old a. o. smith did.

    Good but........
    The water heater is fine. Picking it up was a nightmare. A special order I know. Waited a time for it to be made and shipped to store, That, I understand, but the pick process at customer service needs to be smoothed out,

    seemless install, good to go in 30 minutes!P
    Old water heater died while at work. Wife called and asked why there was water in the garage. I asked her to check where it was coming from. It was from our 20 plus year old water heater. I asked her to check our options and sent me text stating homedepot had one in stock. I called and had them save I for me. After. Work I stopped by homedepot and purchased Rheem gas water heater. Was installed in about 30 minutes, by me! A tireman.Fit like a glove. No problems. Hot water in 30 minutes! Very ... read more happy with purchase!!

    Heats water fast!
    While it has been just a few weeks, we are very satisfied with the purchase. We had another Rheem gas water heater and it worked well beyond the years it was supposed to work! It took, maybe, a couple of hours for a contractor-friend to install the new water heater.

    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

    Absolutely love it
    Just installed it yesterday with the help of a neighbor. It went in easy. Heats the water way better than my 20+ year old unit that I replaced and it fired up right away. Would recommend if you're just looking to swap a 40 gal for a 40 gal and don't want to spend too much time or money.
