Quality Tankless Water Heater
Our 14 year-old Rheem tankless water heater recently failed due to the control board failing. Because of its age, the control board was no longer available and therefore the unit could not be repaired. A friend, who is a builder, said, "I didn't realize Rheem was in the tankless water heater market. We always put Rinnain tankless heaters in our new builds." Hmm. I looked into this and learned that Rinnai is a leading brand in tankless water heaters so I was fortunate to be able to order the RU 100iN from Home Depot. It shipped to the store and was available within a few days. I installed it myself today and I am very pleased with the result. It is very quiet, compared to the previous unit. I can barely hear it running when standing next to it. The installation instructions were excellent and after committing them to memory, I felt comfortable doing the job. I used the Sharkbite water heater kit for the water lines connected to copper lines and they worked perfectly--no leaking. You'll need 3/4" male unions to connect them to the Rinnai isolation valves. The condensate drain was easy-I used a 1/2" female fitting coupled to a 3/8" barbed fitting for 3/8" vinyl tubing running to a floor drain. I was able to reuse the Pressure Relieve Valve downspout from the previous unit. Be sure to use a new 3/4" yellow flex gas hose for your natural gas connection. Venting was easy with 2" PVC. I did the non-direct combustion vent, which pulls air from the room and this required a short piece of 2" PVC and a 90 degree elbow. The entire job took 6 hours and I only used a second person for lifting the unit on the mounting bracket and feeding the exhaust PVC from the outside. I saved $2,300 compared to the cost quoted for installation of a new Rheem unit and feel that I have a superior unit that is high efficiency and has a better GPM output and warranty. Based on the reputation of this brand, I'm assuming it's going to be trouble free for many years.

    Installation was easy and the performance is great. The heater delivers hot water much faster than my old tankless hot water heater. Love the fact that Schedule 40 PVC can be used for venting. Dealing with condensation was a bit tricky because I do not have a drain nearby the heater, so I installed an automatic condensate removal pump (see picture) - it is also working great.

      It was fairly easy to install and operate. You can set the water temperature from 98° to 120°. Be advised that this does need a 110v outlet within about 4 feet. I would advise that you buy the optional brass water valve kit with it. It's about $85 and will make the install so much easier. I think if you bought the pieces separately it would be over $85 anyways. I've had it for a little over a week and I'm enjoying that it instantly provides hot water. I think my favorite part of this product is that it's not using any propane unless I am running the hot water. The days of constantly keeping water hot while I'm not even home are over. It says it needs a condensation kit, so I bought one for about $30. Be careful which kit you buy, because the one I got is a complete piece of junk. If there is a better option get that.

      It was a little difficult to install and I had to get a professional to help, but this is such a cool (hot) appliance. I was skeptical, but decided it was time to replace my hot water tank and the thought of having unlimited hot water was very appealing, as we were only getting about 5 minutes of hot water out of our old tank system for the past 20 years and then you'd have to wait 30 minutes for the next shower attempt. I've waited about a month before leaving this review. I can shower, the wife can shower, kids can come over and shower, grandkids can shower, neighbors could shower (if we wanted them to) and we'd NEVER run out of hot water (unless we ran out of propane). Originally I thought I would save on propane, but now I sing entire albums in the shower - probably using more propane than I did with the old hot water tank. As far as how long the Rinnai will hold up? I don't have the answer, but right now, I'm very pleased with this unit and I'm off to take another shower!

      This is the model to get if you want maximum hot water flow capacity in a single unit at an efficient energy rate. Some pointers that may save you some time: You likely need to upgrade to at least a 3/4" gas line, you need 3/4" PVC fittings purchased separately to run the pressure relief valve drainage, 1/2" tubing or PVC for the condensate drain. If you intend to run a hot water recirculation line I would recommend against trying to link the pump via the "Circ-logic" connection to the water heater. Not only did this require me to purchase a separate connector cable but then I found out the pump marketed for this purpose would not work as designed unless you purchase even more accessories. I ended up scrapping the whole connection and simply have the pump controlled by a smart plug. The water heater works fantastic and the manual is fairly thorough, just a couple minor annoyances along the way.

        Installed the RU180iN myself. I’m not a plumber, but I’m fairly capable having performed many home improvement projects over the years. Because I also replaced all the 70-year-old galvanized water pipes (with all new copper) and replaced all the old gas lines throughout my basement, this was a serious undertaking for me. I did it in stages, spread over four weekends. The installation manual is very well done...also a good amount of information online & YouTube. And I asked Bruce at HD a thousand questions. I love the tankless water heater. It’s been running about three weeks now...no complaints. 120 degrees is plenty hot and I find it to be pretty quite. Standing outside, it’s quieter than my next door neighbor’s power-vented tanked water heater.
