Title: Great hot water heater!
Review: I had the older model from 2010 that finally died with either the fan motor or control board. Pricing these items would have cost almost as much as a new one, so I opted to replace the entire unit. This one was the exact size and all the piping and electrical connections were identical. After prepping the new one (using the same shut off valves and gas fittings), it took less than 2 hours to install!!!! Amazon's price was almost half of Home Depot and other internet vendors. I ordered it Monday, received it Tuesday evening, installed it Wednesday morning! Unlike some of the other reviews, mine came with only a small tear in the corner of the box (which was well padded inside)... not a dent or scratch! Very satisfied with the purchase!

Title: Works great
Review: Love that we were able to install it outside. This is not a DIY unless you REALLY know what you are doing. It is not a cheap install with a plumber. We did an open box with warehouse and saved $250. Give it a try.

Title: Works great!
Review: Our Rennai tankless broke. This one fit the exact specs as the Rennai size and fittings. It was easy for my husband to replace it. It heats up way faster and hotter than the Rennai, even when it was new. Shipping was fast too. We are very satisfied.

Title: Neither Rheem nor Amazon provide support when you need them
Review: I bought this outdoor unit and had it installed according to the manufacturer’s specifications. North Carolina had about three usually cold nights which caused the water in the copper tubing to freeze and burst the tubing. I had several conversations with Rheem and Amazon about the issue. To date, the issue is not resolved. It’s okay. I’ll never buy another Rheem product.

Title: Definitely need a professional to install.
Review: We purchased this to replace our 20+ year old monstrosity of a tank hot water heater. The packaging and instructions are very very good. But I strongly suggest a professional to help install unless you have a construction background. The diagrams and written instructions are easy to follow and have a lot of troubleshooting tips. Our problem was our natural gas pressure was too high for this unit so we had to call in a professional to install a regulator for us. Other than that it runs great and has consistent water temperature. We also love that we were able to install it outside because we have a small home. Customer service was also very helpful to determine the issue to have our gas problem resolved. Overall very happy with our purchase.

Title: Perfect for small homes
Review: Product arrived early and was concerned because the box was damaged. But heater was packed with extra padding and was not even scratched.Installing was easy but may need two people, heater is very heavy.Had it up and working in just a couple hours. Will definitely buy again if this one goes out.Price was great and with Affirm payments works out for a retired person.

Title: Great Working, Arrived Damaged Large Dents In Case, Possibly Refurbished, Signs Of Prior Use
Review: The unit works as advertised, it did arrive dented very badly, not what I expected for an item costing 1k, well I mean, I kind of expect it these days, however, once i pulled the case dents back into some operational configuration, I was able to mount it. 2 parts of the directions could be more clear so here they are....the remote wires use black top and white bottom on both the unit and the remote, they do not tell you this but it is in pictures as this and it worksthe power block is not the part on the left with the bright sticker, and yours may not, but mine had wires preconnected, to the block, it is behind a small metal guard in the center of the unit, again not the part labeled 120 connection, why I will never knowin any case, this heater works very well apart form the inability for companies and sellers to take care of items and send new items when new items are purchased, I like the heater, as far as a seller that would ship an item dented and deformed this badly as new, I have a good spot for them too.....you can elaborate on your own, that is all;

Title: Was very easy to install and supplies plenty of hot water.
Review: It takes a while to get hot water. May need to add recirculation pump.
