Rated 4 out of 5 by 8reviewers.
Rated 5 out of 5 by Works Great and all the Hot Water I will Ever Need I installed this heater 2 days ago and was very pleased with ease of installation and with the heater startup. Will know more as time goes on about reliability and required maintenance. Love the fact that no more worries about being last to take a shower! August 7, 2016
Rated 1 out of 5 by DON'T BUY THIS! I would not recommend this product. We have it for a few years and done numerous repairs on it. The heater keeps kicking off and we have purchased so many replacement parts. It is actually a true lemon. June 30, 2016
Rated 5 out of 5 by The Best I've had mine for 5 yrs. Couldn't be happier. Energy bills have decreased emensly.Only problem, n I'm not possitive this is it, but I bought a new dishwasher when I did the remodel n the dishes did not get clean. So traded it back in n got an upgrade. Still dishes did not come clean. Did some research n one comment said that if tank is far from washer it may do this n some ppl get a small one n put it under the sink just for the dishwasher. I on the other hand tried turning the tanks heat up to 140. This seemed to do the trick, then I just turned it back down. Being single this doesn't bother me. Another option is I could have went with a bigger one, but not possitive that would fix the prob either. All in all I wouldn't have anything dif. N I think it should be a law that these go in every new house built. If ur house is huge get 2, lol. One for bathrooms n one for kitchen. Lol April 5, 2016
Rated 1 out of 5 by does not work Worked well for eight months, now does not work at all. Company no help in fixingproblem. Do not buy this product. January 30, 2016
Rated 5 out of 5 by Best Tankless on the market My dad being a Plumbing Contractor and me being a Mechanical Contractor and selling the Rheem Brand as my main line of quality products it is great wish I had done this years ago. October 3, 2015
Rated 5 out of 5 by Best In Class! Had my old tank water heater replaced with this and it's amazing! I never knew tankless water heaters could produce hot water so fast, and this model keeps the water at an accurate and constant temperature.I can't wait to see my gas bill go down! March 29, 2015
Rated 5 out of 5 by Beats out competitor hands Down I replaced a Bosch tankless I had for about 8 years or so. I had so many problems with it and no help from the manufacturer. So I did research and decided to get the Rheem RTGH-95DVLN. It is wonderful. It keeps the temp at a constant, faster response, and the family has had no complaints which they did every day with the old one. I would recommend this model to anyone who wants the best. Of course my old venting was opposite but I was able to make it work, using new PVC recommended running it through the old vent. Works great!! December 10, 2014
Rated 5 out of 5 by Endless hot water! Had an old tank water heater and will never go back! Love the tankless water heater we bought. Plenty of hot water for our whole family. Wish we would have upgraded to tankless years ago! October 21, 2014
