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.

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.

We have had this a little over 1 week, replaced a 50 gallon power vent tank heater. The Rinnai is much quieter than the power vent. Water temperature is much more consistent than the tank heater. It does take a bit more time for hot water to reach the faucet compared to the tank heater, however only about 15 to 20 seconds more. Professional installation through Home Depot, was very good, however after being how simple it was it could be done easily by a good DYI homeowner.

The actual product is great. Arrived on time when ordered. I was very disappointed in the installation partner process. The local partner assigned by HD quoted 2 to 3 weeks for an appointment just to provide an estimate. I called a local plumber and received a quote and installation in 2 days. I would have rated 5 stars if not for installation.
