20 Best 50 Gal Electric Water Heater (2022 Updated)

I bought this gas hot water heater for one end of my home that services multiple bed rooms, a bathroom, the kitchen, and laundry room. It handles all the needs with out any problems. It took me a little time to install because it was in the attic and I wanted to make sure I installed it correctly! It has been 3 weeks now and no problems.

It comes with great warranty! I do think if my other hot water heater goes out I’m going to give the tankless a shot because it is about 40 feet from attic door and it would hard to manage this beast that far away.

If there are any problems I will update, but so far so good. Service of Supply warehouse is amazing and cheapest I found. And trust me I did hours and hours of research before I pulled the trigger on this unit!.

SupplyHouse has some of the best prices on the interwebz when it comes to hot water heaters. They definitely came in significantly cheaper than local plumbing supply businesses in my area even with business account discounts.

The AO Smith natural gas hot water heater is built great, installed easy and works perfectly upon first initial use. The only thing I would say to watch out for is your timeline. My first unit came in damaged and so I refused acceptance.

SupplyHouse was able to send out a second one that came in undamaged. This did cause a delay in the project and since the shipping is a third party company, I can’t blame SH. Their customer service was great dealing with the replacement.

They made is very easy for me.

Bought this water heater to replace very old WH that came with home we bough. Worked great for 6 years, never ran out of hot water, really never had any problems. Cleaned/drained it every year or so.

Came home yesterday to find top of Dip Tube had completely corroded; steam from hot water in tank was leaking/venting out of the top and water was leaking all over the floor. Very disappointed that this only lasted 6 years.

Is conveniently 3 months after warranty expired. Will not be buying AO Smith brand again.

Just replaced with this unit on 1/15/20 I had a Rheem 80 gallon solar and electric from 1996 till 1/15/20. What a workhorse. Couldn’t have asked for better performance. She started to rust and leak a few tiny drops of water.

Time for a new one. Definately went with Rheem again, only this time around all electric and 50 gallon. So far I am thrilled. I know things are not made like they used to be nowadays. I hope Rheem has kept up the Company standards and quality I have come to know.

Time will tell for sure, mind you I am not expecting 24 years like the last one. That would certainly be unrealistic on my part.

This unit was installed in December of 2017 and as of December 2020, the tank is leaking from the bottom seam. Not impressed with the longevity of this mediocre water heater. I have had great luck with AO Smith and will be returning back to that brand.

After finding out that shopping for a water heater is just a bit better than putting sharp sticks in my eyes, I’m satisfied with the new unit. Finding a 50 gallon ‘Tall’ turned out to be a chore, and then I found out the big orange box store that carries them doesn’t do the installations.

And, their contractor isn’t open on weekends. My ‘go-to’ plumber also carries Rheem, but at a significantly higher price. So I ended paying more money for less features and six years less warranty, but by Golly, I had hot water on Saturday!.

I bought this on June 29, 2022. I am 70 years old, and my son helped me get it down into the basement. I spent about 4 hours hooking it up because I had to extend the vent a few inches. It fired right up and ran for about 10 minutes, then the pilot went out.

Then the pilot would light but the valve wouldn’t sense it, so it would go back out. Reliance told me that the local rep would come out and fix it for free. He came out all right but I had to pay $140 for the service fee and wouldn’t cover the gas valve.

I told him that I would drain it and take it back to the store. I’ll do it all over again, and hope I can get my $140 back.

This heater has a blue cap in the cold inlet nipple that is for energy efficiency, do not remove it. Both nipples are lined with light blue plastic to help fight corrosion, do NOT try to remove! Installation on this heater was straight forward but required modifications to the Cold and Hot lines, the gas connection and to the exhaust flu.

I replaced the 3″ flue (6′ and 2 90 degree elbows) because the old one was rotten and rusted through in places. I upgraded from a 40 gal to this 50 gal water heater because the price was only $40 more.

Total install price without labor was $650. $500 w/h + $150 plumbing supplies and tools to complete.

I picked up the water heater I ordered which was in a taped up box with the corners in rough shape. When I got home and opened the box there was a big dent in the side of the heater. I think when an item has been previously returned in a taped up box, it is the stores responsibility to check it out for damages before restocking it and selling it to me.

So back to the store I go to return it ( wasted time) and of course there are no more in stock. The plumber was coming the next day to install it, so I had to shop elsewhere to get the product I wanted.

This has been my only disappointing experience so far at this store.

Easy as usual. ONLY thing customer’s need to REMEMBER. DO NOT TURN THE POWER ON UNTIL the tank is completely full AND bled. The heating element failure on new water heaters is almost ALWAYS exclusively because of over ambitious customer’s or plumbers turning the power ON BEFORE the tank is full and air is bled off.

See it ALL too frequently sadly. Then a good product gets a unjust poor review.

I purchased this water heater and after being on back order for a few months, which I knew about, it finally arrived. Upon opening the box, which was undamaged, there were a few dents in the water heater.

I contacted customer service and they assured me it would be fine. I checked the inner tank with a fiber optic camera and it appeared undamaged so I installed it. So far so good. My biggest issue is I could have received the same model, scratch and dent water heater from my local plumbing supply for a few hundred cheaper.

This 75 Gallon Water heater installed on Jan16. 2017 failed ( Leaking due to corrosion) on November 28, 2021 or less that 5 years. While it is still under a 6 year warranty this small consolation. My previous experiences in a 40 gallon AO Smith in my previous house was over 22 years with no corrosuon failure.

Got this water heater thru Home Depot to replace a same model that started to leak after less than 4 years due to hard water deposits and minerals in my well water. Was under warranty. After some research, I now highly recommend changing out the anode rod to an aluminum rod maybe every 2 years if you have well water with hard water.

These rods are sometimes hard to remove. (Check you tube) With this new heater, before install, I took out the plastic grommet where the rod is, cut, picked and vacuumed out the styrofoam insulation and removed the rod with a 1 1/16 socket, came out easily.

I teflon taped and pro doped it so it will be easily removed in the future. Mine was 39″, so I know which length to get to replace. I stuffed some insulation into the cavity where the rod is. If you get an egg smell, the rod is likely shot.

I also found the two heat trap metal water connections at the top, tend to corrode in time with the hard water issue, so I plan on changing them every 3 years. Also drain water, 10 – 15 gallons, every few months to remove sediment.

If these steps aren’t done, with hard water, these heaters won’t last and will leak well within 6 years.

I purchased this water heater in the 50 gallon size at Homedepot. I installed it myself and it was an easy installation. However, after allowing several hours for the water to heat I still had WARM water.

Turned on the hot water only and it was barely warm to the touch. After checking all the electrical connections I gave it 24 hours to heat and still only warm water. I called the assistance line where a young lady walked me through the process of elimination and determined that the thermostat was faulty.

ON A NEW PRODUCT. She gave me the options, 1) they will mail you the replacement parts and you will get them in 3-5 days. 2) They will send a technician out in 3-5 days. 3) You can hire a licensed technician to replace it.

Pay for everything out of pocket and you can submit the bill for reimbursement. 4) You can purchase the parts, install them yourself and they will reimburse the cost of the parts if you submit the bill.

Is it to much much to expect a new $400. 00 water heater to work when it is installed?.

Water heater has been in use ten months. Had issues with hot water recovery supply in that, running out of hot water during shower. Contacted your Customer Service who advised trouble shooting procedures and sent one new heating element and later a new thermostat.

Recovery time improved somewhat after installation of items. Increased temperature setting to compensate for slow recovery. Water heater is forty gallons and my previous Whirlpool forty gallon water heater had satisfactory recovery at a much lower temperature setting.

I am disappointed with the Rheem performance. Note: I recommended and helped install three Rheem water heaters for three neighbors before I experienced the recovery issue. None have complained to me about performance.

Very good water heater. Default temp is 140oF which is set hotter than my last one but I’ve left it there so that we can use less hot water at a time. The whole thing is plastic which is why they can provide the lifetime warranty (provided you register it otherwise it’s only 10 year).

Because even the base is plastic, it wobbles a bit during installation – even on level ground – which makes me question the stability when it’s full but so long as you don’t body-check it, you should be fine.

Mine has not moved and it’s been installed for 3 months now. It’s much bigger and taller than my old metal one but that is apparently due to increased insulation so account for the larger size in your space.

When it arrived I thought it was the wrong one because the package read 42 Gallons and I bought a 50 Gallon tank. The difference is 42 Imperial Gallons is 50 US Gallons. Go figure! They advertise the higher number so watch out for that as well.

It seems like a bait and switch but they just use the conversion to their advantage. Aside from these little sales technique things, the heater itself is working very well for me. I look forward to the low to no maintenance of the plastic body – no rods to replace.

Recommend a professional install it for you. I was going to do it myself but there are unseen dangers and liability issues with insurance if you install it yourself. DIYers beware. Not impossible to do but I err’d on the side of caution.

I purchased a new 40 gallon Electric Marathon a couple of weeks ago and installed it last Saturday. The install was pretty straightforward, but when I began filling the tank, the vacuum relief valve immediately started leaking.

I called Rheem support and after 20 minutes on hold spoke with a support representative. Her first question was “whether I was sure the leak was coming from the valve and not one of my other connections?”.

No, I’m looking right at the valve and can tell where the leak is coming from. Okay, “you can purchase a replacement at Lowes or Home Depot and we’ll reimburse you, or we can ship one”. I check with both retailers and neither have the valve in stock, so I ask that they ship one.

They tell me it will be 2 – 4 days before it ships, but I can call back on Monday to ask for expedited shipping. I ask what the cost for expediting will be. No idea, that’s not my department. So I call back today (another 30 minutes on hold) and am told that it will cost me an extra $30 to have a defective valve from a brand new water heater shipped to me more quickly.

The alternative is 2 – 4 more days with no hot water. This is fantastically poor customer service. Once the new valve is installed, it’s possible I’ll never have another problem with the water heater.

But the sting of this poor first experience with Rheem is what I’ll remember, and what I’ll be telling all my friends and co-workers about.

I had been eyeing this tank on the basis that the 14 y. o. + tank in my new home would eventually go. It leaked a year after we closed. Fortunately, the local HD has these in stock (at least always 2 it seems, as that’s how many are always on the floor shortly after one gets purchased).

The tank is very light so a single person is able to move and get it into position with relative ease (we had a dolly so we could wheel out the heavy old tank and wheel in the new one with ease). Installation is pretty elementary.

Hook up the water inlet and outlet, and power. Easier if you don’t have to sweat a joint (or know how to – harder with leadless solder). Do note that the top of the tank is somewhat flexible so pipes may not stay straight up as with a steel tank.

The tank also has a narrower base and is taller than a standard tank so bracing these with earthquake retention straps is a good idea. Seems to heat pretty fast (1 hr to very hot water when we first turned it on).

We’re turning down the thermostats as the default Canadian setting of 60C is too hot. Do note that the box and label on the tank states that the tank is 50 imperial gallons (~227 litres) though Rheem’ website doesn’t list such a size (nothing between a 50 (189l) and an 85 (321l) U.

S. gallon heater).

Very displeased with rheem warranty experience. My water heater burned up and it was apart of a warrant claim. http://www. rheem. com/recalls I called and was sent an email and opened up original case # 525522 where I sent pictures of my burnt up water heater(which I still have my pictures) which this water heater was 4 years old and apart of a recall.

After I sent in the pictures I had talked to a lady in regards to getting the pictures. She mentioned that it was really bad and rheem was going to send me an email so then I can go to Home Depot and find an equivalent water heater at no charge.

But when I called in the next day no one had any clue what I was talking about and sent me an email but they started a new case 527959. Which is really odd they would give me a new case number. they must have gave me a new case number since they didn’t want help out with a recalled product.

The second case number I got the email that mentioned I am now getting a new part instead of getting a new electric water heater. I have yet to see this supposed part that was issued. there is no way anyone can go this long without a water heater.

literally 1 1/2 months. I am truly disappointed with the customer service and time it is taking for this to get taken care of. I had to go out an buy a brand new water heater because I couldn’t wait that long for the part to come in and this was issued 4/28.

I had to spend over $600 dollars on this new unit as well as a $250 labor charge for them to remove and replace the new unit. it is pretty sad because when I first sent the picture I was told that because it was burnt up badly that I should be getting an email in regards to an approval to go to Home Depot and find an equivalent one at no charge.

but when I called since I didn’t receive the email on the approval to go to Home Depot to get an equivalent one. I called then a new case easy wrote up and they were supposed to send a part. I am very unhappy with the customer service since pretty much nothing has been done to get this fixed fast enough done this went out 4/23.

and it is now 6/15 and I still have not gotten any response back from rheem. No one ever get rheem product since they are not helpful at all. This needs to get straightened out because there is no help at all because I am out a lot of money to get this taken care of when rheem should have taken care of a majority of the expense.

I just replaced my older Rheem water heater with a new, upgraded Performance Plus model. Very easy install took only 30 minutes and I turned on the heater. The indicator lights were confusing and the manual was even more confusing.

After going online to the Rheem website, I learned the new, two element tanks were designed to switch automatically between upper and lower element. Everything was fine, although the manual indicated there could be a problem with one of the elements.

The thing I find quite troubling is that this issue with the operating manual was identified in reviews going back more than 5 years. It would seem that a company that supplies such good products would be anxious to correct that simple issue that has caused so many home owners such concern.

I bought & installed the 40-Gal. electric version less than 2 years ago for our vacation home in the PA Pocono Mountains. It’s installed in a small utility room in the basement where we only power it up when we’re there for a visit.

It worked fine initially but recently started giving us Leak-Detection alarms which, since there’s no indication of a leak, I assume might be due to the higher humidity conditions there during the summer months.

I clear the alarm to turn the automatic shut-off valve back on and it restores operation for 24 hours. only to have the alarm reactivate at that time. I’ve called Customer Support twice just to be given directions on how to access the moisture-sensor and dry it off.

Since it’s still under the 3-year “unconditional warranty” period, I was hoping for a visit by a service person but that didn’t happen. I tried having a fan move the surrounding air with no success. Operation seems to be better in the winter months when the utility room is heated and, I assume, drier.

Unfortunately there’s no way to deactivate the leak-detector alarm or change the sensitivity. it sure would be nice if it had one of those options!.

I bought this thinking that it would actually be the last water heater I would have to buy, particularly due to the “Lifetime Warranty*” in big print. As it turned out it started leaking around the fittings after 2-1/2 years of perfect service.

After talking to Rheem customer service they said I could return it to Home Depot for a replacement. When I returned it there I was told that the replacement would be prorated and that they would only give me a store credit of $699, far short of the $1,100+ cost of the Marathon.

I ended up buying a Rheem Performance Platinum for half the price of the Marathon and felt like I had been let down by both them and Home Depot. After posting a negative review of my experience on Home Depot’s site I was immediately contacted by Rheem both by email and phone and I cant tell you home above and beyond they went to make the situation right.

They said that while this unit has been around for quite a while, there has been an a very occasional issue with leaking. They offered to refund the difference in purchase price and the install labor with no fuss from me.

They were pleasant, apologetic, and stood behind their product completely. A very rare thing these days. While I can’t necessarily recommend this product, I can without a doubt say that I recommend buying any water heater (or other product) from Rheem as their customer service is absolutely first rate.

I bought this water heater four years ago. For three years it did very well, but then started having issues. The water became very hot (148 degrees) on its own. It stayed that way for two days and then stopped heating.

Upon total inspection, the bottom heater element had burned out. One of the thermostat controls also burned out. I had a good bit of calcium/lime buildup in the tank, especially the bottom. I had great difficulty in draining the tank because of this buildup.

I replaced both heating elements and both thermostat controls. The tank started working again. However, I am afraid that soon I will have the same issue with calcium/lime buildup and the same thing will happen again.

Let me say that I think this Rheem water heater is a great design, especially the tank material, with ONE exception. I really wish the designers had cut a small oval opening (big enough for a large hand to fit through) towards the bottom of the tank which could be removed after draining and used to totally remove buildup in the bottom of the tank.

The hole provided when removing the heater elements just isn’t big enough to efficiently clean out the tank. Other than this issue, this water heater is one the best.

I have owned the Water Heater for close to a year. I noticed an immediate cost savings in my electric bill, despite the fact that I set the temp. to 135 degrees on the unit. I set the temperature higher, as we often have guests and this may lead to 3-4 adults showering in a row.

The heat recovery of the unit is phenomenal and it is able to give each user a hot shower. Since I have a water heater that is placed under the house, it was an ambitious project trying to install the water heater as I had to disassemble the entry door frame.

But, other than that challenge, I have loved the engineering and execution that went into the development of this HWH. I never knew this HWH existed before I began doing some research, you should encourage Home Depo to have an active display.

even if it is just a cardboard mock-up of the unit. I know that as soon as I saw the plastic tank, warranty and the ability to withstand moisture that other HWH typically fail to stand up to. I knew this water heater suddenly became my 1st and best choice.

Once I took some measurements and determined I could get it into the crawl space I never considered any other design. You did a fine job in the design and execution of this product. Well done! Joe Sannino.

I bought this water heater thinking that if I paid a few extra dollars for a smart one, I would save money on my electric bills long term. Wrong. The SmartHQ app that you have to use to control this heater is so lame that you cannot do something as simple as set a schedule to turn the heater off for a few hours in the middle of the night.

You can manually turn the heater on and off or adjust the temperature from your phone – and that’s it. My old dumb water heater had the same functionality, I just had to actually walk over to it. The horrible app is my biggest problem with this heater, but I should also point out that it arrived in an error state.

The first time I turned it on, it began beeping and showed “F6” on the display. I started pressing buttons and got it to quit beeping, but I was unable to set the temperature or connect it to my phone.

Luckily it was actually heating water to a default temperature, or else it would have been a much bigger problem. I ended up having to make several phone calls over the next week to GE customer service, with them telling me different things to try.

Finally some one told me to press a sequence of buttons three times real quick, and that cleared the error. Weird. My entire house is full of GE appliances and have had really good experiences with all of them – except this one.

Either save your money and get a non-smart version or try another brand with more capable controls.

It’s very good and clean, I don’t know about electrical usage because there was not enough time since the review request email was sent to me. So far I have indeed benefit of that extra water volume heat, it did improved my life as I have a large bathtub that the previous 50 gallons unit would not be enough, now it can get enough for a comfortable use of that bathtub.

The painel is super easy to use. Hopefully it won’t get bad overtime. The app is… bad. Has a lot of bad practices in that app. It requires login to the app, what means that in the future GE might shutdown their servers and the app won’t work further.

It’s very slow to open and will stay locked (you can’t do anything with any appliance in the app) until it finishes loading all the appliance list. The app crash in the iOS often or not update the latest state of the appliance.

It doesn’t work with Google Home or Apple HomeKit. The app is a gimmick, GE doesn’t take it seriously, but the physical painel for the smart version is helpful.

They keep asking me for my review so here it is – I completely regret this purchase. Our water heater that came with the house started leaking, so I thought “let’s see what Costco has to offer since I always get quality stuff from them”.

Well this isn’t one of them. Our bathroom faucet, right next to the water heater, would always get hot almost instantly with our basic water heater. Now it takes at least a full 60 seconds of running on full blast to get some warm water.

The kitchen has to stay on for a good 5 minutes or so before it even gets hot water. The app is pretty pointless. It just lets you set the temperature, capacity, and vacation / away mode. But right now after one rolling blackout in below freezing weather, the panel shows F17 error code (which the manual and their app give different reasons).

The app acts like everything is fine with the heater, but it won’t heat any water. I had to search the self-help feature on the app, and the description in the app is different than the user manual. If this were any other Costco product, I would’ve taken it back after a week, but since it’s such a pain to drain and install, we’ve just dealt with it.

But I wouldn’t recommend this water heater to anyone. Apparently everyone else in the neighborhood with their 15 year old, cheap basic water heater, all have hot water in this freezing cold. But not us with the one month old new heater.

Very poor accuracy and temperature stability. I set the upper and lower thermostats at 125 degrees F and the water temperature ranges from 105 degrees to 120 degrees as measured with 2 digital thermometers.

I cannot depend on getting a nice warm shower because of this. Very disappointed as my previous unit was a Kenmore and the temperature was always accurate and consistent for the 17 years I owned it. I chose this GE water heater because I thought it would be high quality but it apparently is not.

As a Professional Engineer and retired QA Manager, I can appreciate the thoughtful design features and build quality of this HWH. My old HWH (diff brand) was just 5 years old and also had digital controls but lacked leak detection with auto shut off of water+power.

When its old expansion tank suddenly failed the water spray toasted its controls, the 220 volt junction box was arcing, and there was other damage to the Laundry Rm. This new HWH could have saved me $2000+ and a lot of trouble! Long term reliability is unknown but I expect it to be fine.

I did not connect it to WiFi because that isn’t necessary for the leak sensor and auto-shutoff to function. (BTW, use of leak detection shut-off feature is optional, as the floor level sensor can be unplugged.

A diff brand has reportedly had false trip issues with its bottom-of-HWH sensors. ) We also didn’t use the utility grid control feature because our utility doesn’t give a decent $$ incentive. But both of those can be very nice features for others.

to use. I’ll amend my review if there are any HWH problems but really don’t expect any. Two Thumbs Up for this A. O. Smith HWH.

I bought and installed the EE9-50H55DV myself with the help of a friend. My previous hot water heater had broken and it would be over a week before a plumber in my area could come out. Had a friend who maintains an apartment complex to help me install it.

We unhooked the old one and put in the new one within 10 minutes. When you turn the power on to the unit it will cycle through for about 5-10 minutes on the digital display and then it’s ready to go.

You can manually adjust the temperature on the display or follow the directions to connect to the Wi-Fi (I would advise connecting to your 2. 4Ghz signal rather than the 5Ghz as most devices like this seems to operate mostly on this frequency).

The thing that sold me on this unit was the fact that my old water heater was a 40 gallon and this one was a 50 gallon and also the ability to connect to my phone on the AOSmith app to be able to control and monitor the energy usage better.

It will also alert you if the hot water heater is having an issue! Win, win for me!.

I bought this water heater at Lowe’s on August 24, 2022. It is not the one we wanted and if we ordered the one wanted, it would have been a month to get it. We decided on this one. We do not care about all of this wireless extra stuff.

My wife just bought a printer and can’t even hook to internet to get wireless, so it is pointless. Not everyone has the luxury of this. Ok, so far water heater is doing its job. It states to have water set on 130 degrees but getting burned every time you turn the hot water on is a bit much.

Way too hot for skin contact at this temp. so, we do know that the thermostat is working properly. It did leak at the top where you connect the lines and was able to tighten lines without stripping. It was fairly easy to install on my own.

Gauges on front panel easy to read and to enter the correct temperature. We did put in the 130 degrees and left it there for about 2 weeks, but that was just too hot. It’s too early to really give a recommendation, that is why I put 4 stars.

Give me at least 6 months and I’ll give you an update.

This version is much much more quite. It runs longer as a result but still doesnt use that much power. If your not familier with permanent magnet motor tech, look into it as this is what it uses. Like the 22 plus seer hvac systems this is just reverse.

It will dehumidify the garage as well as cool it down by 10 degrees (mine did). The exhaust is cold instead of hot. Trust your wallet upon instalation, it will pay you back in electric savings. The product arrived on time in great condition and so far no issues.

I got this water heater to replace my oil-fired water heater that gave me endless hot water and home heat. I am glad to be off oil! The heat will be replaced with a heat pump. I have not run out of hot water yet and I do not expect to.

I think it has only used the heat pump to keep the water hot. I am currently running in “Hybrid” mode am going to try “Efficiency” mode to see if that works. My electric bill went up $10. 00 for the month but I am not sure that was all because of the water heater.

The sound is twice as loud as a refrigerator. I have a 1632sqft 3-bedroom split entry home with 2 full baths, one with a deep tub and large rain shower head. Longest shower I have taken to date was 35 minutes.

The unit is installed in my garage and is set at 140 degrees. The installation was difficult because the input/output on the unit are not on the top. Be prepared to replumb your piping and plan where your condensate is going to go.

Plumbing codes differ from state and county so do good research. Be sure to install additional heat traps made out of the pipe, they work well. If you are tired of burning or want an electrical upgrade this unit is worth the price and hassle.

My AO Smith Hybrid electric water heater’s heat pump compressor quit working. AO Smith was contacted and they approved a replacement from the original supplier, which was SupplyHouse. Called SupplyHouse and gave them the authorization number, was put on hold for a minute or so and then advised that they would be shipping out a replacement.

It was shipped out the next day. It was as easy as ordering the original one.

I had this Rheem professionally installed by a Rheem Pro Partner on 01/24/20. The first unit that was installed turned out to be defective on start-up and the installer had to return it to Home Depot the same day and install a second one.

No biggie, I thought, at least the second one works and I have hot water. I couldn’t get the EcoApp to install on my phone, but again, I thought, no biggie, I don’t really need to control my hot water tank over my phone.

Now, just 16 months later, although the red “Service Needed” button isn’t on, the control unit has started beeping persistently. None of the buttons on the control panel are responsive and nothing will stop the unit from beeping.

Two units in less than 18 months? I won’t be burnt by Rheem again. So disappointed – I bought this unit to replace a basic 16 year old Rheem which had functioned beautifully.
