I would have given 5 stars but the first unit I received was defective. There was an internal leak which after calling Rheem Tech support , I was informed it was not reparable in the field. Home Depot sent out a new unit within 3 days. I returned the defective unit to a local Home Depot for the full credit. The best decision I made was to use push connectors for the plumbing. Without those replacing the defective unit would have been a much more difficult job. Rheem Tech support is great. I am not a plumber and I was able to install this myself-- twice in this case--
-- Do yourself a favor and run gas piping directly to the unit-- no flex hose. insufficient gas flow will not be noticeable at first but will case Hugh Headaches later in clogged burners.

While this is installable by a knowledgeable DYIer, there are several points where a DYIer can get into trouble.
I decided to relocate the unit about 10' from the old LP tank water heater to make the intake/exhaust installation easier. Even if I had used the old location, I would have been forced to build new hard-copper lines and run a new 3/4" LP gas feed so a minor move of the unit was not really that much more work.
Things to consider:
You need a 3/4" gas feed. While my homes main trunk was 3/4", the 10' branch to the existing LP tank water heater was just 1/2".
You should purchase the correct hookup valves. Another $80+.
While you are at it, install a scale-protector such as Aqua-Pure AP430SS Hot Water System Protector. About $65.
If you don't have one, install an expansion tank. Another $40. (Many areas require such for any new water heater installation.)
Hard copper tubing is not cheap for DIYers.
By the time I got done, I has spent $1900 total for the unit and I did all the work. Although, since I am a perfectionist, I did use a little more brass threaded pipe fittings where I could have used galvanized, but I don't like to have brass valves and other items with galvanized nipples between them.
Now, we never run out of hot water on Sunday mornings. The only usage problem is when my wife shaves in the shower. She turns down the water flow to a minimum and that is too small of volume to keep the heater heating. So, her water gets cold and she has to wait for the hot water to get hot again. I am trying to train her to leave the water flowing enough to keep the heater heating.
One installation suggestion. Don't glue all the joints in the exhaust or intakes. Use a silicone bead to seal one joint at each end so that the exhaust and intake pipes can be removed for inspection or unit repair. (Install silicone bead after pipes are together. Don't actually put it into the joint where you would have put the glue.)
Note: In the pictures, you can't see the sediment trap on the LP line, but it's behind the valve.

Rated 3.0 out of 5.0 by hippiemom Eh --- not so sure
The water takes up to 2 minutes to turn hot. I turn on the shower then do a few other tasks while I wait for it to heat up. And this is in August. I am afraid to see what will happen in the winter. Also, it does not get very hot, although the installer said he set it as high as it would go. I don't have to turn any cold water on to shower, and it is not hot enough to wash & sanitize dishes, Very disappointing.

Rated 5.0 out of 5.0 by Dave Amazing, hot water? no problem.
So the water heater in the basement was an old LP powered unit that was about 23 years old. It made some strange noises and I don't think it was ever really serviced. It was installed in an inconvenient place between a wall and the furnace also. Due to my travel schedule I always worry something will fail when I am gone. I asked around and found out not much due to tankless not being popular in this area. Tried to get someone to install it and found no-one interested. Ordered the unit and read the book. Thought about it for a few days and went and bought what I thought I would need. I have never done any plumbing or worked with black pipe for the LP but am somewhat of a quick learner. Measure carefully.`Its in and works better than I imagined. Its very quiet and runs without issue. No problem making plenty of hot water. One thing I suggest after talking to the person at Home Depot. Be sure to get the rinse, shutoff, valves available. They are about $100 but make complete sense once you see them. I learned this after the install and will have to put them in later because they need to be ordered and my project was underway already.
Would I do it again? Yes
Would I recommend? Yes
Easy to install? Yes
Unit works good and is quiet? Yes

Rated 1.0 out of 5.0 by Lars 2 years and no support from Rheem
I had this unit for 2 years with 2 problems. Gas valve problem and water flow sensor, both parts sent free of charge from Rheem. When the heat exchanger started leaking, Rheem said replace unit. The "replacement" means they offer you fair market value which is about 1/3 of the new cost. They should put that in the warranty that replacements are pro-rated, not a direct zero cost replacement. They said to keep costs down that's the best they can do. Not happy with Rheem.
Poor quality and poor customer service. I will not buy or recommend any Rheem product.

Easy to order online, shipped quickly, and installation was a breeze.

Rated 4.0 out of 5.0 by Bill Working flawlessly but is loud.
I installed this unit about three weeks ago and it has been working great. This is not my first tankless water heater but it is the first time I have purchased a Rheem. I had been waiting for a model that uses pvc for intake and exhaust when this one finally came onto the market. The water heater appears to be well made and installation went smoothly though this is definitely not a job for a do-it-yourselfer. The only issue I have had with it is that it makes a considerable amount of noise when running, this is why I am giving it a four star rating. I will probably have to sound-proof my entire utility room to cut down on some of the noise. The noise mainly comes from the blower, Rheem should spend some time developing a blower that is not so loud. Keep this in mind when choosing a location to install this unit in your home.

Rated 4.0 out of 5.0 by Greg Just installed - works well
I am a DIYer - Took us ALL day to install, but we took our time and none of our water or gas connections that we made leaked at start-up. Once completed, we turned the unit on and water poured out of heater box! Opened up the cover and found a hose clamp was lying in the bottom of unit. From the factory, one of the connection "O" rings was not seated properly and the looking at it, I know the hose clamp could never have been attached properly at the factory. I pulled the fitting apart and re-seated the "O" ring, attached the missing clamp and turned the water back on. No leaks! Blew the water out of the unit and let the circuit board dry. Fired it up (plugged it in and turned on the gas) and it worked like a charm! How water comes out well. Unit is a little noisy, noisier than our old "tanked" water heater, but not an issue as it is in the basement. This was last night. Had a long "hot" shower and look forward to many more....
