NO! This unit does not require any external electric power source. So when our power goes off we still have hot water, day after day.

Why does my water heater keep turning of

Asked by David October 26, 2015
10
Answers

If it is the same problem as mine, the pilot light does not always light the gas instantly, then you get a nasty BOOM! that knocks the pilot light out. When I contacted customer support, they refused to assist as I could not contact them "while this was happening". This happens to mine sometimes daily, sometimes it will go a week or more. It probably just needs some sort of adjustment, but Rheem was no assistance whatsoever, making their warranty worthless.

Asked by APFotoUS August 10, 2018

Answers

This is NOT a condensing hot water heater. It requires 'B' type vent made of metal at least the size of the vent stack on top of the water heater. It must be run at an angle uphill until you can go straight up and out of the roof through a roof jack designed to work with the type of 'B'vent pipe you use. You must also have at least 1" clearance all around the 'B'vent to any combustibles. PVC pipe cannot be used ever on this type of hot water heater. Be sure to check local building codes as they may be stricter.

Simple enough for hubby to install. Basically, not rocket science. The old one was apparently 17 years old. Same brand. It lasted a lot longer than their projected time. From my experiences, with appliances, I HIGHLY advise getting their extended warranty. They are the ABSOLUTE BEST at taking care of their customers. After flip-flopping between them and L's, Home Depot definitely delivers on their customer service. Except their curbside pickup, which is "buggy". I did have to go in. The bonus discount, from my Depot card, was FANTASTIC! During this epidemic madness, this has been a nightmare of a time to replace things. Thank you Home Depot!

Summary: I bought this Rheem 40 gallon, 36,000 BTU water tank to replace my A. O. Smith 40 gallon water tank that started leaking after 14 or more years of use. I considered a tankless water heater option, but decided to go with the Rheem unit since I would be able to install it myself, and would cost considerably less. Using HD delivery service, and adding in the cost of new water heater connectors, other plumbing accessories and a new flex gas connector, the total cost came to about $650. I also had to pay $110 for someone to haul away my old water tank after removal. While I had some installation challenges (see below), overall, I am very happy with this Rheem water heater since installing several weeks ago. Installation: It took me some considerable time to install this new tank since it was 5 inches taller than my old tank which required me to change position of the new tank on the stand to be closer to the existing plumbing lines. (Diameter was the same - 19 inches). This required adding wood supports for attaching the earthquake straps, and using a 90 degree elbow on the house feed line only. I used the Home-Flex connectors since the bends were very sharp and these connectors are much more flexible than the copper connectors used with the old tank. My neighbor helped me lift the old tank off the stand and put the new one on – each weighed about 125 lbs. The most time-consuming effort involved determining how to connect the temperature/pressure relief valve to my existing plumbing for this purpose. My home has ¾” copper plumbing that would take any water from the temperature/pressure relief valve and exhaust it to a location outside the garage. In order to use this plumbing, which was to the side and slightly behind the new tank, I soldered ¾” copper male adapters to the existing exhaust plumbing and to the copper tubing from the TP valve. I was then able to use a flexible braided water supply line to connect the TP line to the existing plumbing (see picture). I also had to do some rearranging of the vent at the top of the tank to connect to my existing flue. I purchased and installed a 48” gas flex connector, which was longer than I needed, but the only one available at my local Home Depot – this turned out to be the easiest part of the installation. Despite all the installation challenges, I am pleased with the installation and expect the Rheem water tank will be a good replacement for my old water tank.

Good water heater at a great price
Quality :

So far so good. I installed this water heater myself 5 days ago. It took some time and a couple of extra trips for a new stand and vent piping but otherwise was smooth. I'm not a plumber and the hardest thing I'd ever installed was a dishwasher. This was definitely harder, but in the end, it was worth the $700+ I saved to have someone else install. I went from a 21 yr old 40g Rheem to this 50g Rheem and noticed the difference when taking a shower. No more adjusting the hot water as the shower goes on. I had considered a tankless system but was looking at $2,200 - $3,000 for unit & installation. After reading some maintenance issues folks were having with tankless, I decided to stick with a tank. Ladies, if I can do it, so can you!

Went to my local Home Depot to buy this unit after researching the internet, got to the cashier and got $50 bucks off of the list price of $389 after applying for a Home Depot credit card. So that was a added bonus! Brought it home and installed it in a few hours, and it fired right up and took a nice hot shower a few hours later with no problems so far. Happy with the price and quality!

Bought on Saturday, installed on Sunday. Gave a seven-flash red LED error code, meaning Bad Control Valve. Called Customer Service and they said they would send me out a new controller. I thought it would be overnight, next day, or at least 3-day shipping, but that was in the days of caring about customer service. I received the part Friday afternoon and it took about 15 minutes to install (not counting draining the tank). It works but I don't have any confidence in this thing. The controller electronics are way too complex to be reliable over the long haul and they did not even conformal coat the boards for protection from water and corrosion. By the way, a new controller for this from Home Depot costs $282.09.

Leaking Drain Valve
Quality :

Value :

Old water heater went out and decided to replace it with this one. Upon finalizing the installation, went through and check to make sure everything was screwed in and secured tightly. Come to find out the pressure release valve was just half twisted and could have easily come off if any pressure would have happened in the tank. Not the greatest in terms of quality control/inspection on Rheem's part. Finished up the install and check in it later at night. Come to find out that there was still water leaking and that the drain valve was constantly leaking water. Called customer service and Rheem will be sending out a new part within 2-4 business days. I was offered express shipping but I would have had to pay for that myself. The fact that the drain valve isn't working properly, and the pressure release valve was not secured upon initial installation, makes me VERY nervous about what else might be wrong with this product. Very frustrated about the fact that I have to now service this product and it hasn't even ran for more than 24 hours.
