  • Amazing product! Very happy with my purchase!
Style: Natural Gas, Indoor Installation Size: 9.8 GPM
I almost never write reviews, but felt compelled to write one for this purchase. I bought this product over a year ago, and wish I would've done it sooner! I went through two hot water tanks in 15 years and wasted so much money due to inefficiency. This heater is extremely reliable and have yet to have any problems with it. We can easily run two showers at once and have laundry and dishwasher running all at the same time. This heater can pump out a tremendous amount of hot water. The average shower requires 2.5 gallons a minute. If you do the math, 9.4 gallons is alot. It can take up to 20 or 30 secs in a large house to get hot water but that's no different than a hot water tank. I installed the unit myself no problem. Venting the unit through the concrete foundation was the most challenging part of the install. It does require some plumbing skills but all in all wasn't bad. I think placement of the unit is really important and should be as close as possible to your venting location. Ofcourse you also need to have your cold water feed, proper gas line, and a nearby outlet to power it. I mounted it on plywood which I tapconed to the concrete wall. For the water feed I recommend extending your water line with Pex, mainly because its easy to work with and its cheap. I know this unit is saving me alot of money in natural gas. My old tank was a zone off my hot water boiler which meant my boiler was running year around, even in the summer when it was warm out, just to keep hot water tank heated. Now my boiler only runs half the year and the on demand heater kicks only when hot water is needed and doesn't waste gas when you're not using it. Fantastic product! I removed the front cover to take a look under the hood, it looks well built with quality parts. This prompted me to put one in my 5th wheel camper. I can't say anything about customer service because I haven't had any reason to call them. I don't think there's much more to say except I highly recommend this product and is worth every penny! ... show more

  • No complaints and I definitely would recommend
Style: Propane, Indoor Installation Size: 7.5 GPM
Update as of 11/1/21.....OK... hot water stops(off and on) midstream without an obvious reason, so called for the repair guy.....1st time to do anything in almost 10 years. Update as of 7/5/17.....Still great, and have had zero issues. Update as of 11/12/14.....We have had our Rinnai installed now for about 44 months and it works extremely well. There can be a delay in hot water, or a cold water sandwich; if you change temperature quickly or turn off and then on after having it on for 15 seconds or more. It probably takes 30 seconds for ours to really heat up, and maybe 40-45 seconds to get really hot water in the dead of winter...this is slower than a tank heater and the only detriment I can note or am aware of at this point. Puts out plenty of HOT water for us as we can have 2 showers and laundry going in the dead of winter...it is no problem. We adjusted our tank to put out 140 degree water and we love it...again, especially in the winter. My wife used to fill our tub, and the old water heater would actually run out of hot water(it is a large tub).....this is never a problem again! I think beyond 3 uses at one time(shower, laundry, dishwash, etc) running you would have a capacity problem...or extrememly cold basement. There are two of us here most of the time with the occasional guests....2 1/2 bath, and Rinnai is in the basement and very close to our main shower/bathroom, so this helps the time as our upstairs shower can take a minute to get hot water when its cold. Also, getting water temp correct with a single turn knob may be an issue....the water temp only goes so low before it will cut off....but we found the minimum spot which is hot, but we turned up our Rinnai so we could get hotter water and ideally, more use or capacity at the same time. By the way it is not uncommon for our basement to be 50 or so degrees in the winter and this easily overcomes that. I cant say how much cash it has saved us really, but our propane bill has definitely not gone up...and I estimate our electric bill had actually dropped 10 bucks/mo., and that was with our electric going up 9% last year, and another 5% this year. We replaced the original house water heater that had gone bad after 6 years do to salt water getting through our reverse osmosis/charcoal filter/saline filtration system(we have very salty well water on the coast)and it backed into the original water heater due to a valve being left open....and then it literally ate our water heater from the inside out with just one soaking of brackish water(took about 6 months to destroy it, of course we didn't know it was happening until the rust color started to show up) but once the water started turning rusty it was obviously too late(and this was only a 6 yr old water heater. Also, since we have a whole house well reverse osmosis and double charcoal filters purified water running, we shouldnt have to flush our Rinnai like you are supposed to do with these every year(our water has about 60ppm tds), but you are supposed to flush/clean every year to remove buildup and sediments(we pay enough up front to not have this issue unless our filter goes bad or salt water gets through usually by human mistake). We paid less for this than our local plumber could buy them wholesale through his supplier(by about 150 bucks total). He said there is an even more efficient tankless Rinnai available if your interested? This got here in 2 days and just make sure to order the venting pipes and gas taps if you need them! We had our whole system installed for 1350 total.....so it cost us about 500 bucks more than a good replacement standard tank water heater....I am sure we have gotten this back or will be very close by the end of this year. I believe we have saved 15 bucks per month on average? Make sure your gas pipes have enough flow.....Ive heard this can be an issue also? We really love ours. If anything happened we would probably just upgrade to the more efficient unit. Our unit is about 3 years installed now, maybe longer and I see others have issues, but we really have to recommend at this point. I will edit should anything come up as I think this needs to last at least 12 years for the return to really pay off. Propane and electricity is getting more expensive and this helps through efficiency to combat costs. Installed 03/2012 ... show more

  • Excellent unit, highly recommended.
Style: Natural Gas, Indoor Installation Size: 9.8 GPM
My previous 50 Gallon Rheem water heater gave out after 18 years and after some research I decided to go with the Rinnai RL94iN. Being somewhat of a handyman I decided to do the install myself. The first unit arrived as scheduled but damaged. The factory packaging from Rinnai is flimsy so inspect your unit when it arrives. I notified Amazon and I had a replacement unit delivered within 24 hours and in perfect condition. Kudos to Amazon for prompt courteous service. The unit also ships with a set of Webstone Service Valves included, no where in the product description does it say this, so I had to return the ones I ordered. Note to Amazon: Update the Rinnai product description so other customers don't make the same mistake. The hardest part of the install was fastening the backer-board to the concrete wall in my basement so I could hang the Rinnai unit. Once that was on and secure the actual install of the water heater, including rerunning the water and gas pipes, took about 6 hours. The actual cost of materials for the install, including the Rinnai unit, was about $1600. My local plumbers gave me estimates of $2200-$3700 to put in a 50 gallon tank water heater so I'm happy that the install was simple enough that I could do it myself. The unit has worked perfectly since we turned it on. It is quieter when running than my previous Rheem Powervent system. Yes, it takes an extra 10-15 seconds before the hot water arrives, but that is a small price to pay for the savings in space and energy consumption. ... show more
