    • Works GREAT so far!
Style: Natural Gas Size: 5.3 GPM
Previously, I had an old Electric water heater. I can't complain, it lasted 17 years with minimal maintenance. Decided to look into a tankless due to the electric costs being so high. I purchased an outdoor unit, since I didn't have any previous vents to the outside. It is super quiet and sometimes I have to go outside to make sure it is working when the hot water is on. The new Rinnai tankless has only been installed for a month but works great! Even survived the cold Northern Indiana winter so far. The heater has sensors to keep the pipes warm within the unit but be sure to protect the outside piping going to the unit from the cold. Hot water everywhere in the house and at the same time. Never installed a tankless water heater before, but with many videos on you-tube about Rinnai water heaters, made it easy and answered all the questions to know what to do. Two settings, Factory default is 120F, tested with a temperature gun and was getting 117F at the faucet. 140F degree setting is producing 133-135F at the faucet. If it saves on electric cost, it should pay for itself within a year. Should have done this years ago. Definitely has exceeded my expectations so far! ... show more

    • 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! ... show more

    • Very good. Buy it
Style: Propane Size: 5.3 GPM
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

    • it heats water...
install was fairly painless as far as the unit goes. I chose this as the time to learn to solder plumbing so that stretched things out. I move my water lines and got a bigger gas line to replace the one going to the old hot water heater. I ran it for 2 days with no vent on it. I just kept the back door open so no chance of carbon monoxide poison. I wouldn't recommend doing this but I'm OUTRAGEOUS!! Unit worked fine. washed a few loads of clothes. dishwasher and a couple showers. No problems. I wish it would get 10 degrees hotter. 120 is not quite good enough. I guess there's an Addon to make it go to 140 which would be nice. sucks you have to pay more for it. !!!!!!! IMPORTANT !!!!!! It doesn't come with a vent kit And the instructions all refer to their vent setup. Here's the important thing!! Its a direct vent unit. Not knowing what that meant I connected a 5" vent to the unit. It slides right in past the rubber gasket. Perfect fit I think. Turn on the hot water and 20 or 30 seconds later BOOOOM!!! it blows up. Well that was scarey. Panic and look for a fire. shut off the gas. nothing really looks wrong so I try it again. Booom. hmm. I called roto rooter on a sunday before memorial day and a guy comes out and tells me its back-drafting because my gas line is to small. I change to a bigger supply line. Boom.... Glad he didn't charge me for the service call... OK so now im going to call my hvac buddy to come out. But in the middle of the night I have an epiphany. The 5inch vent pipe coming out of the top of the unit has a smaller 3 inch pipe inside. Its the 3inch inside pipe that is a vent. The outside is actually the fresh air return. See new houses are well sealed and if the unit didn't have its own fresh air return it would create a vacuum in the house and not work. Sooo. I ran a 3" pie from just the exhaust of the tank and left the fresh air open to pull from inside the house. We are in an old condo that is far from sealed so no issues with a vacuum. muahhahaha,. working like a champ now. So what was happening was with a 5" pipe around the whole thing it was trying to intake and exhaust through the same pipe. It would blow out the flame because there's not enough oxygen in the exhaust gas. Then the gas would build up and the ignitor would kick in and blow it all up. ... show more
