Rheem Water Heaters Reviews

I purchased my tankless direct 5 years ago. Roughly in the first year it started throwing error codes. I tried several times to make contact, both by phone and by email. I finally reached someone through email because of a bad review I left. The person immediately gave me a runaround on the reason for the error code and said it wasn't the product. After several interactions he got what he wanted and that was for me to just go away. I spent several years running up and down my stairs resetting the system to take a hot shower. I am now 66 doing chemo and can no longer do the shower marathon needed.

Rheem sucks. I just replaced my old Rheem water heater (we had many issues with it too). I purchased another Rheem against my better judgement because plumbers claimed that they were better quality IF bought from a plumbers supply. However- my current plumber did state his poor opinion of Rheem also. But I got one anyway. Guess what! Straight out of the box it was defective. It was leaking gas from the central gas control. So I called Rheem and already started the warranty process. I get the new part and call my plumber. The plumber advised me to just get a new unit because it’s a red flag to have to fix something right out of the box. So I attempt to call Rheem again WITH my plumber. They do not offer a solution for me to replace the entire unit. So now I will have to pay the plumber an additional $300 on top of the price I JUST paid for the brand new unit. Do not buy Rheem!!

Terrible in every way. Water heater is 6 years old, failed as soon as the warranty was up. Ordered a part 9 days ago that still hasn’t been shipped. Customer service is a joke, transferred me 3 times then gave me a different number to call that started the whole process over again. No one could tell me the status of my order.

We had a Rheem electric tankless water heater installed in Feb 2026. July 2026 the heating element busts. Customer service is limited and a waste of time. Our plumber called them and asked for replacement parts. Rheem said they would send 4 elements but only sent 1. Less than a week later more issues and waiting for the plumber to appear with the number 1 heating element. Our plumber thinks it's actually a problem with the flow sensor. Personally I believe this is a defective unit and should be completely replaced. We shouldn't have to keep paying a plumber to come see what's going on with a new water heater.

Reamed by Rheem. Make sure you read the fine print on your Rheem water heater warranty before getting stressed out about it. The company has the worst customer service, and they do not even listen to your side of the problem. The warranty states that to Please have your unit drained, disconnected, and returned to the point of purchase, for a like-model replacement. We also recommend you review their return policies and bring your receipt. So they want the average person with very little plumbing experience to unhook the bad water heater, lift the 200 lb tank into your vehicle and return it to the third party vendor that sold the water heater.

I purchased an expensive Rheem hybrid water heater. Today, after 1.5 years, the compressor stopped working and tripped a code T009 compressor fault. I called their customer service number and was cycled through AI and then put in a queue at position "21". I then spent 6.5 hours in the queue and after 6.5 hrs, when I finally reached "next in queue" the system hung up on me!!

I’ve had this Rheem water heater for a little over a year, and I strongly recommend avoiding their products. I’ve never had to fight with an appliance this much. This water heater has been nothing but trouble, and it’s easily the worst purchase I’ve ever made.

I wish there were negative stars. Exactly 364 days after I bought the water heater the pilot light won't stay lit. Rheem said to call the gas Company to check the gas pressure. The next day PSE&G came and the pressure was ok and said what was bad on it. Rheem's guy came at the same time and agreed and ordered the part from Rheem. Of course Rheem sent a cheaper part that consisted of 1/2 of what was needed and didn't work. Now they closed for the weekend and the HVAC guy gets busy. I'm Without Hot Water For 10 Ten Friggin Days. JimD1. Rheem is NOT like the Rheem of yesteryear!!!!

My RHEEM water heater died again! I say again because it was a replacement for the one that died earlier. The replacement however is not covered under the standard new product warranty. So now I'm spending $1600 on another water heater. I was told by the customer service supervisor “if we honored the full warranty on a replacement, we’d be replacing them ALL THE TIME”. So it’s just a crappy product! So frustrating!

Rheem hot water tank components were defective before we even hooked up the hot water tank. A tech came out and ordered the parts and we waited for two days and still not received the parts. Went and bought a different brand of water heater. So we are left with $1000.00 piece of junk that we can not return, I call that stealing.

Re: Model PROG40 - 38N RH62 40 Gallon Gas Hit Water Heater. How convenient that it has a 6-year warranty! They die the moment they turn 7 years old. What a bummer!! Lesson learned I suppose!! The cheapest option isn’t always the best choice. I am almost 50 years old, and have never heard of a tank going out before 10 years.

Stay away!! Purchased one in late 2022. Many restarts after installation. 3.25 years later and now it will not light. After one hour on the phone, they agreed to send the parts. However labor was out of date and not covered. They told me the parts would ship the next day but was not even packaged then. Had to pay the plumber to come for nothing as no parts. Now will have to pay him again if the parts ever get shipped. In the mean time, we will be at least a week without hot water. They say they are doing their best. NOT GOOD ENOUGH!!!

I am now waiting for my 4th water heater to be installed since December 2025. The first one leaked, the 2nd was so badly damaged it had to be replaced. The 3rd one was also badly damaged when we went to pick it up. Now we are waiting for the 4th. This is totally unacceptable. I would never buy a Richmond brand water heater again.

My experience with Rheem customer service has been nothing short of disgusting. I reached out to Rheem related to a hot water heater not functioning properly, it was determined that I need a relatively small replacement part that would be shipped to me, this is a residential hot water heater that this resident would not have hot water without this part, 8 days later the part was not delivered, thank goodness I had the good sense to look online for the part and received it the next day and repaired the unit, the follow up and product delivery from Rheem was dismal, awful customer service, if it was wasn't for on line my family would have been 8 days and counting of no hot water, completely unacceptable and total failure by Rheem.

My advice if you're looking for a hot water heater or any kind of hot water product do not buy a Rheem! I replaced my first rheem that only lasted 4 years (supposedly 9 yr tank) when it leaked (sprayed) out the side missing the drip pan and collapsing my family room ceiling. Put in a brand new supposedly 9-year hot water tank lasted almost exactly 4 years from the install date and started leaking out of the bottom. Their warranty amounts to you taking the tank out and bringing it back to Home Depot so you can get another worthless piece of crap rheem water heater that won't last half its life. Never EVER buy a rheem!
