    • Good value
Style: Natural Gas Size: 5.3 GPM
Easy to install with basic tools and knowledge, does not come with hose kit, but works quite well. Keep in mind that this is an outdoor rated unit, not for mounting inside. The only issue I have had in approx 1 year was during high winds, it had trouble maintaining flame stability and temp. No issues over the winter with temps in the teens this past winter in South Louisiana. ... show more

    • 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

    • How lucky are you? Rinnai ducks warranty.
Style: Natural Gas Size: 5.3 GPM
My unit did not work upon installation by a certified plumber. If you do not use a certified plumber for installation Rinnai will not even talk to you. You are on your own. It was coding a #19 which was said to be an unusual code. The plumber called Rinnai for assistance did some things got it working. The extra fussing cost $128 labor that I had to pay. 8 days later the unit stopped working. Called the same plumber. The service call and diagnostics was another $193 only to find out the unit is totally defective. Rinnai did send a replacement at no charge but I had to pay the installation charge at $384. Rinnai likes to have what is called a kit put on at installation. It is used to flush the heater as maintenance. This requires a pump vinegar bucket and hoses. You would need to purchase these things or have a plumber do it at a cost. This should be done at least 1 time each year. So the install price including the Kit and all other necessities was $656. Plus the extra labor charges for a grand total of $977. This does not include the price of the heater. This is my experience in Texas near Dallas. Nearly 2 thousand dollars for a water heater so far and the clock is still ticking. ... show more

    • Great unit, but overkill for my casita
Style: Natural Gas Size: 5.3 GPM
I think this is a great buy. It installed easily (but needs mains electricity which most tank water heaters don't need, so plan on that wiring), no leaks, very tidy ...everything I was hoping for, except I underestimated the lag time before getting hot water. It is mounted just beyond the bathroom for primary use, but, even with a short run, most people are done washing their hands and disappointed before the warm water shows up. Its not the fault of the unit, just something you wouldn't think of until after. I like the unit, so when I have time, I will transfer it to our main house where it will service the bathrooms in the back half. It's design will definitely keep up with showers. I will just need to find a smaller, faster heating unit for the casita, but almost impossible to get small in natural gas. ... show more
