Review: Amazing Product - I've waited nearly 2 months before I wrote a review. Here's my summary: 1. The installation is easy if you are replacing an existing unit, I replaced dual tank water heaters and relocated the tankless heater closer to the majority of the water users in the house so the installation was more time consuming and difficult. The instruction manual is awesome, take the time and read thru it (prior to buying) and follow it strictly. I bought a gas fired unit, had the gas company come out and validate the inlet pressure and ran all the calculations recommended. Installation took 4 days since I had to run additional gas piping, extend hot and cold water lines and install the vent piping to the exterior. 2. After you've read the manual, plan your installation carefully (vent, water in, water out, gas piping in, power). These all converge around the unit which isn't large and will take planning to make it fit and functional. Purchase all the vent pipe ($$$), water piping, gas piping, and valves for the unit (the bundle of all of these are not inexpensive) 3. The unit fired up after the second try (it had to vent the air out of the gas line on the first attempt). The start up was very easy. 4. My wife likes HOT water, the unit is delivered with a maximum of 120 degree output. I queried the internet and found the program button sequence to get it to 140 degrees. It worked instantly, but after an hour the unit reset back to 120 degrees and the process wouldn't let me place it back to 140 degrees. I called the service desk and gave my number for a call back. 30 minutes later, the call came in. The service tech asked a few questions so she knew which unit I had purchased and then I communicated to her what I had experienced. She told me that the code I had used was for a different unit and she directed me step by step how to program the unit. (I had the panel open and performed as she told me each step). It took 30 seconds and the unit has worked correctly ever since. 5. The closer the unit is to the usage point the faster the water heats up, so don't have expectations that you'll get instantaneous hot water when there is 20+ feet of cold water in the pipe that has to be pushed out by the hot water, but it does heat the water extremely fast and it's on the way as soon as you open the hot water faucet!
Review: Very good. Buy it - Have had this up and running for almost a year. Have had no problems, works great. It’s outside and the lowest temperature it has seen is about 5 degrees. Worked great the whole time. No water pressure issues, and it gets hot very fast. 10/10 recommend

## Questions & Answers

**Q: How does very cold intake water affect performance?**
A: My input water temps change with the seasons, this water  heater controls the amout of heat being produced at the burner, to maintain output water temp. at set levels. I set my water temp to 115F and regardles of input water temp. it stays at the set output.

**Q: Will you please list EVERYTHING you will need to install this unit?**
A: In addition to the Rinnai unit you will need a termination vent kit and a isolation valve kit. (The isolation valve kit is included with all models NOT beginning with "V".)  MyPlumbingStuff

**Q: Is this unit sufficient for Tennessee climate?  I've read somewhere that it was for warmer climate areas (Florida/Texas)**
A: Hi S. French. I live in New England which is mixed climates: Hot/Humid summers and in winter dry/colder climates.  It's an indoor unit, which is in my basement, so I'm not sure how sensitive the climate is related to operation of the unit.  If it were outside I would think it would be of more concern.

**Q: Does this unit come with controller?  rinnai tech said i needed a mc-91-2us controller? do i need to buy separate?**
A: I bought model V65EN.  It came with a wired digital controller.  The installer did not run the wire into the house and mount the controller indoors. 
 He simply set the controller at 120 degrees and left the controller inside the unit.  If I want to change the temp, I have to take the cover of the unit.

### ⭐⭐⭐⭐⭐ Very good unit. Tricky install. Need special vent pipes, not your old ones.
*by N***N on November 12, 2022*

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, pre-drilled the screw holes, and then used light cord to pull the "mask" up from above, up on the roof. Once I had it placed properly, I used a right-angle drill to drive in the screws from underneath. Don't forget that you'll need a flashing unit on the roof to make a good waterproof seal, and also some roofing tar to further seal it. Be careful when lifting the shingles to slip the flashing unit under them to avoid breaking them. If you do some minor damage to the surrounding shingles, use the roofing tar to compensate. Once installed, the unit works very nicely with the caveat that it does not seem possible to set the temperature above 120°F. That's really sufficient, but my old unit was set at 125°F. Not a deal breaker. If you've not had an on-demand heater before, be aware that when running hot water, there's a lag before you actually get hot water. With this unit about 20' from the kitchen sink, that's about 30-45 seconds before the water warms up. Overall, very happy to have hot water again, and this unit outperforms the previous, larger capacity unit it replaced. Install a phosphor filter upstream from the unit to reduce maintenance flushing. Do install the valve set that will later permit de-scaling the boiler tank. This is important for the longevity of the installation. TIP: use the woven steel, flexible pipes to connect the unit to gas, inlet, and outlet pipes. These are much easier to work with than their copper counterparts, which are hard to bend-- MUCH easier. Good luck. If you prepare well ahead of actually doing the job, you will greatly reduce the stress factor in carrying out the actual installation. Do your homework. YouTube is your friend. ... and DO read S. Brewer's excellently written and potentially very helpful exposition on the entire process of installing these units. p.s. If you need hot water in a hurry at your taps, you'll want to spend the extra spondoolix for the unit with a recirculating pump: it's a luxury, but if you prefer faster delivery of hot water to your taps, you'll want that version of the heater. Cheers, N.
