Do not buy a Rheem water heater. I drained my 2 year old Rheem classic gas water heater as recommended and it would not restart. In troubleshooting I discovered a known issue with the gas control valves. I contacted Rheem as it was still under warranty and spent almost 4 hours on the phone going through their troubleshooting and warranty process. They finally admitted the known problem was due to a faulty Italian part (GCU) they used when they ran into supply chain problems during the pandemic. I scheduled an appointment with one of their certified/recommended partners and got an estimate on $800 in labor. I received the part from Rheem and installed it myself in an hour. They do not stand behind their products but did give me free shipping as a "courtesy."

Having problems with our new Rheem Hybrid Water Heater in that energy savings mode (ESM) is not working properly. Temperature is set at 120 degrees and in ESM mode only (other settings are fine) the faucet temperature is around 113 degrees. We had it checked by a technician and there were no error codes and was told by Rheem that because there are no error codes it is working fine. Right! They also told me to raise the temperature setting which is band aid approach. To compound the issue I have a recirculating pump and was told by Rheem that these Hybrid units are not compatible and you need to run in high energy mode which is more costly. The pump causes the water heater to run more often and will shorten the life of the water heater. Something the company that sold it to me was not aware of. Still trying to contest it but Rheem is dragging its feet.

Bought an Air sourced 270L Ambient Sidevent Rheem Heat Pump Water Heater installed 1st August 2024. We are always running out of hot water and the water heater doesn't turn on when its supposed to i.e when you turn a shower or hot water tap on. The panel can be on 5 bars and 60 Deg Celsius but after a 20 min shower can be down to 35 Deg Cel and 1 bar. We have 7 in the family and i was told it was big enough for 6 people. Rheem keeps directing me to the plumbers as though it was their fault.

Please don’t buy this water heaters , the customer service doesn’t help at all, they told me that my unit was under warranty for replacement , one time , after that they said it was a bad installation, after that they told me that they will replace the unit , at the end is one month wasting my time and they said it was a bad installation, those units are the worst quality ! I bough one at Home Depot , I will start a claim with my lawyer because they can’t hurt people like this , please don’t buy those units , the made garbage , better pay a little more and get a good product , if you have friends please let them know that , my tank is 3 months old and it have a leak , the tread of the tank is broken and they don’t want to accept that , my lawyer said that we will get all the money back plus all the damage caused by this piece of crap product

In early September we purchased a Reem hot water heater from Home Depot. They have their own company that brought it out and installed it. Three days later, the alarm went off, saying it needed service. The gentleman came out, re-sealed everything, then left. Less than 24 hours later the alarm went off again. This time they came out and replaced it. This was on Sept. 12, 2024. Fast forward less than a month later. On Oct. 8 the alarm went off again. It took two days for the plumber to get here. He called Reem and they said the Mother Board needed to be replaced. They ordered a new one and it will take 8 days to get here! Apparently shipping overnight to keep their customers happy is not important to them. And during this entire time, we have no hot water! Their products are crap and their customer service is even worse. DO NOT BUY A REEM WATER HEATER.

Worst customer service I have ever experienced. Replaced an instant gas water heater unit under warranty and it didn’t work 6 hours later after the technician left. This was on a Tuesday….. called the customer service centre and the soonest they could get a technician out was Thursday and they considered that to be priority service. We now have no hot water in the middle of winter with kids for two days. The customer service rep was in no way apologetic or sympathetic and said if I had an issue I should call back tomorrow when other staff were back in. Far from the kind of service I would expect from company that consider themselves a ‘trusted brand’.

We purchased one of the more expensive Rheem gas hot water systems - a 155 litre unit with a stainless steel tank and no anode. It lasted less than six years and for the last two years we have had to put up with water at only 40 degrees as the mixing valve wasn’t working properly. Very disappointed and unimpressed. The Rheem company clearly doesn’t care about quality any more. So we’ve gone elsewhere for our new HWS.

Wow, This is probably the most crooked company I have ever dealt with. My one year old water heater failed. I called Rheem to honor the warranty. They sent their specific plumber. He told me that since it was installed wrong, that they would not honor the warranty. He went on to tell me that over 99% of all hot water heaters are installed wrong. Which means that Rheem won't cover over 99% of warranties. I am a general contractor and I have had over 200 houses. I have never seen a water heater hooked up the way he said it should be. I also called 20 plumbers who agreed with me. He also went on to tell me that his particular water heater was horrible, and if they honored the warranties on them then they would lose too much money. He also told me that Rheem wouldn't sell me the parts even if I wanted to pay to fix it. The whole experience was surreal and creepy.
