Rated 5.0 out of 5.0 by Quick easy install Having never installed a water heater this was a breeze. DIY saved about $500-1000. The staff in plumbing helped me through any questions I had. The toughest part in removing the old heater and putting the new one in its place. The rest is just plug and play. Whole install took about 3-4hrs with breaks. Only problem I had was that the initial start up was difficult and I couldn't get it to light. So I decided to try again the next morning and sure enough the first starting cycle it lit up and I had hot water. Not sure if it was due to air in the gas line? Last water heater lasted 27yrs I hope this one will as well. September 25, 2014
Rated 5.0 out of 5.0 by Best Water Heater incredible deal Just installed yesterday, Installation was straightforward and instructions comprehensive. Heater has quicker recovery and starts and stops with little variation in water temp at tap. New self diagnostic control is a great improvement over my old manually lit pilot water heater. Replaced 15 year old rheem heater that would not keep pilot lit. Paid $337 on friday and price is $429 on website today (sunday). Still an excellent price point for a rheem heater. April 20, 2014
Rated 5.0 out of 5.0 by Very good quality and easy operating system Very easy to install. Purchased and installed 2 of them. February 17, 2015
Rated 5.0 out of 5.0 by Excellent Heater for the price. Bought the unit yesterday at Home Depot. Even helped me load it into my car, The guy was skeptic that it wasnt going to fit, but I reassured him it would. Just installed it tonight, ran into a couple of snags. The turn offs on the copper pipes were to low for the provided water pipes. I had to run to Menards to get an 18" pipe for the hot side and a 12" pipe for the cold side. I also had to get a 24" exhaust pipe, but I knew that before. The compression fittings worked great and the old gas pipe lined right up with the new heater. All in all with the trip to Menards and the cleanup and a haul of the old heater to the curb took about 4 hours. Hauling the old heater ( a 17 year old Ruud) was the hardest part of the job. Luckily my daughter was home to help me slide it up the steps. The rust was just falling out of the old heater as we rolled it down the driveway to the curb! We really got our use out of that Ruud! Theres a 6 year warranty on this Rheem; which in todays throwaway society is pretty good. I dont expect it to last 17 years however.I also noticed that this heater weighed about half of the old one, but everything is made cheaper and lighter these days. I was impressed by the heaters performance; the water was warm in just a few minutes. I turned the dial to the second lowest setting and the water is HOT! I have to warn the rest of the family to be careful! Overall the heater is quiet in operation(I guess I got used to the perculation of the old one). This one seems like a Cadillac in comparison. I made up a hose long enough to reach the sewer drain so I can flush the tank out after every season. Should help prolong the life of the tank. (I dont think the old Ruud was ever flushed). They dont make em like that anymore! September 11, 2014
Rated 5.0 out of 5.0 by Don't forget the installation kit! As with any water heater, dont forget your installation kit. They sell one for about 40 dollars that uses compression fittings and braided hose and a flex gas line. Also you may need some 1/2 to 3/4 adapters if you have 1/2 copper going to your old heater like I did. You could reuse your old screw in adapters but good luck getting them out. I love the even temperature the unit provides and also the capability to put you in a burn unit at the hospital if you wanna turn it up that high. May 15, 2014
Rated 4.0 out of 5.0 by Just had this one installed through HomeDepot The look is very nice, I like the thermostat and the status light code feature. It delivers 67 gal. Of hot water per hour. Good for a family of 4. April 7, 2014
Rated 5.0 out of 5.0 by Excellent water heater! I had not planned to replace my water heater---the old heater was still working after about 20 years. But when i touched the side of the heater one day---the metal really flexed inward, so the shell of metal around the tank was almost rusted completely away--time for replacement. I went on line---checked the water heaters at Home Depot and found the one that would work for me, in price, in quality and ease of installation. The website, even told me how many were in stock, and at which store(we have two stores fairly close to my home) and in which aisle they were located. That is service! So, i went to the store the next day, an employee helped me load the heater for checkout and another helped me load it into my vehicle after the purchase. Happy customer! January 21, 2015
Rated 5.0 out of 5.0 by Best water Heater Preformance of all 3 homes we owned. Just had it installed... we are impressed with the quite operation. The temperature is set 20* cooler than our old uni,t and the water is HOT! (Hotter than the old Whirlpool of 8 yrs.) The people at Home Depot really sell some great stuff. There installers are excellent. They cleaned up after themselves and made sure the unit was operating the right way. They must have checked for leaks a 1/2 a dozen times. So we are safe to say this purchase again was done right the first time. The product is working beyond expectations. We will continue to buy from our local Murfreesboro, TN Home Depot Store!
