CUSTOMER REVIEWS

Rated 3.1 out of 5 by 33 reviewers.
Rated 5 out of 5 by Easy, Easy, Easy Works great for my 2 bath house. Solar installed and bill is still zeroed out. Gas bill cut in half. I installed the unit myself, wiring and plumbing. I don't do these for a living but have an understanding and respect. I had to adjust the flow for the faucet for my tub. 2 showers work great. More room in garage now! September 24, 2013
Rated 5 out of 5 by Good product My previous unit's manufacture is no longer in existence so I was not able to obtain replacement parts for it. Therefore, I chose a company that has been around for a long time. Another reason I purchased this unit was because it required very little flow rate to it to start and continue to heat water. This is a helpful feature if you need to have a small amount of water running for a long time. The only curious thing was the manual stated it required no maintenance but a paragraph later said it would last longer with preventive maintenance. Then, it never said what that the maintenance involved nor how to do it. When I plumbed the unit, I did so with cutoff valves before and after the unit. I also included two other valves so that I can "descale" the unit in place. The installation was relatively easy. I already had the electrical service to the unit and only had to change the breakers to match. This unit required fewer circuits (2) than my previous unit (4). Of course, the plumbing had to be modified. February 3, 2013
Rated 5 out of 5 by Works Great We built a small cabin at 2,200 feet elevation. We did not want a tank water heater to have to drain each winter. We researched the reviews on all the tankless electric heaters and this one had the most consistent results. We purchased the 27 kw model knowing the ground water temperature from our well in winter would be a challenge and we have more than enough hot water to handle a shower and washing machine running at the same time. This product met all our requirements. Saved space in a small cabin, no draining 40 gallons for winter and it provides hot water in the same time a tank heater takes to get the water to the tap. All things considered an excellent purchase for us. February 25, 2012
Rated 5 out of 5 by best thing i've bought in years. works great and never runs out. i bought the 27k electric rheem tankless water heater in feb. the installation was easier than expected. the hardest part was working with the 6 gage wire. don't try wire nuts, use the wire clamps that can be tightened. you should also use a large enough box to give space to work with the wiring and keep the clamps from touching. the plumbing is a piece of cake. be sure and put a shutoff on the cold water line just before it goes into the tank. after the plumbing ts done, let all of the hot water lines run for a few minutes to bleed the air and check for leaks. now you can let the wife go shower without her complaining about running out of hot water.

Rated 1 out of 5 by Three of these failed for the same reason for us I installed this model in August 2011 at our cabin. It worked flawlessly for a year and then the Intake connection started leaking. Since it is a compression fitting, I gently removed, checked the fitting, added some liquid pipe thread seal, re-installed and it leaked worse. Tried a new pipe, new compression fitting and the leaking just got worse. Returned to HD, Rheem shipped me a new one. Easy swap out. 1 year later, same leak. same process, returned to HD, Rheem sent me a new one. 1 year later, leak again. I AM DONE WITH THIS HEATER. It is too bad as it works really well. My suspicion is since the cold water inlet on this heater is part of the actual heating chamber assembly (one solid unit in to out), that the temp extremes are just too much and the housing cracks at the inlet side. If this heater was being used at a gym or something and running 24X7, I could understand it might wear out but at a cabin that gets used every other weekend or less, it should not fail just sittng.
