Rated 1.0 out of 5.0 by pipemn35 Poor Quality - works for 2 years tops!!!
The first one I bought was DOA (red flag) and got this replacement ordered on 6/19/12 at Home Depot in Hurricane, WV. It was installed around August 2012 and it died right after Thanksgiving 2014. So about two years or less is all your going to get out of one of these. I haven't seen where anyone has had one longer than that. So I guess I was lucky. It was in a detached two story garage with a full bath and I bet it didn't have 1000 gallons through it. The board on these are extremely fragile. Remember only 1 year warranty. Should have done my homework before I bought this unit or paid attention to the red flag. Guess I will go back to tank heater. Even the other brands have similar problems.

Rated 3.0 out of 5.0 by Todd Great Performance, Poor Reliability
I bought this unit to replace a standard water heater that leaked and caused major damage. First, for any tankless unit, there are hidden costs, unless you do the extra work yourself. Tankless electric heaters draw a lot of current, and this unit uses two 40 amp breakers. Unless you have these near your water source pipes, you will have to run power from your breaker box to where the water heater will be located, cost: $700+. Water lines must also be configured to rise vertically and turn 90 degrees to be connected on the sides of the unit, cost $500. I used this unit for almost a year, and it performed well for a home with one bath/shower. Then a few days before the 1 year parts warranty ran out, it quit making hot water. A professional plumber diagnosed the problem as being a failed flow regulator, and the unit's design meant that the whole heater had to be replaced. I received a new unit free of charge, and had it professionally installed. Six days later, the hot water suddenly dropped off to luke warm, and yet another professional diagnosis was required (all of which costs a minimum of $89 per call). The verdict is that one of the two heating units in this product failed, and the unit is now operating at half power. I am now faced with removing the unit and sending it back a 2nd time, but I am becoming skittish about the reliability of the product. When it goes down, I spend at least a week without hot water, and I expected this product to last ten years, but so far, I can't get even one year out of two heaters. I'm going to get a third one because I don't want to have to reconfigure the water lines for a different brand, but if a third unit fails, I will switch brands anyway. This is a great product--when it works--but long term reliability is an issue in my experience.

Rated 4.0 out of 5.0 by MX353 Super Hot Water!
Our house is under construction and needed something small and electric. The unit works great and the water is scalding hot! The shower has endless hot water but I don't recommend using the hot water in sink at same time as shower (shower gets cold). Because of it's size it was perfect for our application. This is a huge energy consumer while operating and your lights will dim and possibly flicker. It uses 2 dedicated 40 amp breakers and 2 runs of 8 AWG wire. I would have given this 5 stars for it's awesome heating power, however was a little disappointed that none of the pex fittings would just hook right up. It uses a 5/8 compression fitting and requires a little creativity and reducers to keep it in a small compact area.

Rated 1.0 out of 5.0 by Justin do not buy you cannot get parts for this item
the water heater is only one and a half years old the company will not warranty the electronic board. and you cannot buy a replacement board you have to buy a complete water heater for $500. electronic boards probably only worth $75. really bad company for not caring replacement parts

It delivers endless hot showers and see no difference on waiting for hot water vs. my old tank type heater. I like the maintenance free by having an electric unit. The electric hookup is designed where you can run on 2 separate breakers but I ran #6 wire (100 feet) on one 70 amp breaker and works just fine. The unit arrived in 3 days.

Rated 4.0 out of 5.0 by simple1 Was very happy with my tankless system
I have had my tankless hot water for 4 years and never had any problems till now due to the hard water in my area. I will buy another but this time will add a descaler or an ion exchanger to help with the quality of the water.

Replace a 50gal electric with this tankless. As advertised, you will need electrician to install the 220 line. Don't try this yourself. From a Cold start, it takes less than a minute ( 30 sec) to get hat water to the kitchen sink. This is a small (1000 sq ft ) redo DIY house that is being renovated, so this should be more than enough. With the 50 gal, we were shutting off the water heater every time we left for a couple of day. We did the plumbing( with help of old retired plumber to help) and hook up was a snap. Again, make sure the electrical is done right, as this is a 220 line and it will use power.
No instruction were included, but it was not hard to figure it out. Cold line goes to cold intake, etc.

Rated 1.0 out of 5.0 by Bummer They quit working after about a year.
On my second unit and it just went out. Same thing as before. The switch that activates heating the water stops working. My first one went out just under a year so was under warranty, but my new unit is at about 1 year and went out again. To discouraged to even try to warranty. switching brands. I will never buy Rheem again. And will push other brand to friends and construction industry coworkers.
