Despite other reviews that I read before buying this unit, I purchased it anyway as it seemed like the best value for the money. I needed a tankless water heater powerful enough to run 2 full bathrooms (showers and baths simultaneously) and based on the wattage and GPM it seemed that this would be sufficient.
I had to special order this unit from Home Depot, as they didnt have it in stock. It took about 2 weeks to arrive.
After receiving the unit I installed it, it was very easy to do and took less than an hour to get the unit hung, and connected to the power and pipes (I already had power and piping from our previous water heater.
The final moment of truth - no hot water. The units green light was on, but when we opened the valves we didnt get any hot water. Checked the connections again - and still nothing. Called in our electrician to make sure that there wasnt something wrong in our box or on the circuit to the water heater. The electrician found no issues, and concluded that the issue was the water heater.
Removed the water heater, and contacted home depot. Was told it would take 2 more weeks to get a replacement. I ended up purchasing a different (smaller) point of use water heater from another retailer - couldnt wait 2 more weeks for hot water and returning the defective unit.
Buyer beware - these water heaters have a reputation for not working as intended - and lots of DOA's. Check the online reviews.

We hired an electrician and a plumber to be sure the tankless water heater was installed to specifications. Installation went without a hitch. We have plenty of hot water. Very good product.

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!

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.

Working great and very glad I made the decision to install even though very few people had any real knowledge about this product which I had to research on my own. Makes plenty of hot water in my condo, very efficient and is saving me money, too,

Takes to much power when operating. Trying to get the power company to run bigger overhead lines in order to satisfy this unit. I would not recommend this product to anyone save yourself the headache and install a gas heated one

Rated 5.0 out of 5.0 by jim640 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.

The inelt and outlet pipes were soldered into the unit crooked, which means we had to mount the unit on the wall crooked and do some fancy piping to get it to line up (not great for my OCD husband). Heats at sink faucets well (up to about 120 degrees F), but even at the lowest possible pressure, with only hot water on, the shower is luke warm at best - and we have low flow showerheads! This is with only the shower running. Ughh. I bought the biggest, baddest unit (RTE 27) and I can't even get a hot shower. I'm going to give it a day or two to see if it needs to be "broken in" (our previous unit improved after a couple of days), then I'm taking it out and returning it.
