I would highly recommend this tankless system to anyone.

Lori Chase: I was able to install this myself but I have 40 years in residential construction. I did have a pipe fitter do the gas line because I had to move my propane tank for other reasons anyhow. I love the way this thing works. I probably could have gotten by with a smaller model. The only issue I have is that the temp setting is in 5 degree increments. I started at 125 but that was a little too hot so I bumped it down to 120. After a few months of use I am very happy.

Roger J Reeves: I purchased this on Amazon and installed it myself. It was easy to install. It is an extremely efficient heater. The only drawback is that when you first draw water it is cold until the heater fires up which takes about 10 -12 seconds depending on how far the water has to travel. It’s something you get used to and don’t stop the flow completely or the heater will shut down and recycle again. I found that setting the temperature at 120 allows you to run just the hot water at the faucet. Other than that I am happy with this unit.

Netizen: The piping that, in my case went up through the crawl space, then through the roof was tricky to install. Ordered all new pipe after measuring carefully and cataloging the fittings I'd need (45's, 90's, and so on). Make sure to order the right diameter double-walled pipe. Look online. I ordered online and the company actually shipped the same day, and it came the next, which is nice if, like me, you are without hot water in the interim.

S. Brewer's review is excellent. He covers all the crucial points very well. He explains clearly what you will be faced with if you decide to DIY the job. It was challenging. When you get to the point of lifting the unit up to hang it on the wall while simultaneously marrying it to the vent pipe, a second set of hands would be a major plus. I did it myself, but a second set of hands would be real boon at that point.

I was able to use the existing hole in the roof, but, as it turned out, the contractor who built the house preferred to cut a gigundo hole in the roof instead of doing the geometry to accurately predict the penetration location and hole size. To compensate, I created a plywood insert with a proper hole cut into it,...

David Allan: We have this at our campgrounds in our 45’x14’ Northlander. Works great and easy on the LP. Was easy to setup and easy to winterized.

S. BrewerS. Brewer: Tl;Dr version: READ THE INSTALL MANUAL before buying. I've scanned through some of the negative reviews for this unit and it's very clear a good percentage of them simply did not read the manual before buying and just assumed it would be a simple drop in replacement. Bad assumption. The manual spells out all the requirements and every additional item you will need to buy.

Before you even try to answer the question of whether or not you can install this yourself, call your local city clerk and see if a permit is required to replace a water heater. If it is, then you're dead in the water before you even begin. You'll need it professionally installed. But if that's not the case...

Things you need to know before purchasing:

1) Read the manual! Especially the section regarding gas line requirements. Depending on how far your water heater will be from the gas line point of entry, how many bends there are to get there, and the pressure supplied to your house, there is a chance that you will need to replace every bit of pipe between the meter and the water heater.

2) The gas inlet on the water heater is 3/4". Even if the rest of the pipe meets the...

Rick Whissell: Best value I could find for the money but there was no mention of the special condensing vent kit that is required with heater. Also the kit was not available on Amazon, I found it on wayfair at a great price but this all delayed my install.

Brad P.: Bought this unit in replacement for the 10 year old R53C unit I had. Very happy, more flow then the old one and no issues with low flow taps not kicking in the hot water heater. Also no issues with running multiple devices of hot water at the same time, just a slight pressure change but not cold or hot shock in the shower tub etc. Would recommend to anyone, very impressed with the speed of shipping.

Moshe Z.: Product works great. It needed a Natural Gas to Liquid Propane conversion kit (ordered from Rinnai, was hard to get). Also required a regulator (ordered from Amazon) to work off a 30lb propane tank.

Once conversion kit and regulator was installed the tank worked well. Hot water arrives within 10 seconds or so. We paid an electrician to run 120V to it, and a plumber to hook it up.
