    • Very happy so far.
Size: 7.0 GPM Color: Gray
Took about half a day to install it. We went out and bought a tall 23 gal. Propane tank. Got it filled for about $100. Now we will see how fast we go through the propane. We started with the temp at 120 degrees. Wasn't quite hot enough. We turned it up to 130 degrees and we are getting plenty of hot water! Doesn't take long for the water to get warm. But it's only a short distance from the Master bathroom. The 2nd bathroom takes a little longer. It's the guest bathroom, so not too concerned. The unit itself isn't too big. It's mounted to the house on the outside above where the old tank was. Actually looks very clean and nice. Hoping this continues to work perfectly for a very long time. :) ... show more

Size: 7.0 GPM Color: Gray
I owned a competitors it worked This is very nice technology Safe and very efficient I'm sold... One thing is the company parts department is lacking... I called to get the cover for pipes long wait time 55minutes got transferred to warehouse they said yes we have 450 in stock... Cool can I get one? Yes go online and place incart select buy... You think I didn't already try that? Anyways it said in-stock placed in cart than said no longer for sale. Called next day waited again long time the said I'd have to buy a whole install kit I didn't need said okay went to buy it and wouldn't you know it unavailable. I'm very understanding but this is just a cosmetic pipe cover for a brand new unit. What if it's a important part? Heater 5 stars customer service 1 star Could be a deal breaker for some But I've never called competitors customer service I'm sure it's just a similar run around Best heater I've owned ... show more

Size: 8.4 GPM Color: Gray
piece of CRAP, i have installed three Rheem water heaters, this one lost me over 800.00 as we installed it an airbnb and it kept going out on us, so the gas company did their thing and that didn't work, plumber tried to help, nothing. so i had two cancellations and a bad review becasue of this wtr htr. I have had no issues with the other Rheem products, but this one was a nightmare. hoping to get my money back for it. ... show more

    • Provides enough hot water for our house
Size: 9.5 GPM Color: Gray
We’ve been using it now for about a year. It’s lowered our electric bill by 1/3 which is awesome. Our home is about 2800 ft.² and it provides hot water to every portion.

    • excellent hot water heater
Size: 7.0 GPM Color: Gray
This replaces 15 year old Them tankless heater. The only issue is I run this on 40lb propane tank and had to upgrade regulator from 3/16" id hose to 3/8 id hose. On cold mornings I would get code 11 and if I turned on second hot water faucet got code 12. The 3/16" I'd line did not provide enough volume. Likely running on regular large propane tank would likely not be a problem. Would recommend at least 3/8" id line or larger. New regulator was rated at 160000 btu with 3/8" id line. Hot water heater is rated at 160000 BTU. ... show more

Had to install 3 units to get one that worked properly. Internal gas sensor failed on 2 brand new units. Even gas company was perplexed by the units throwing 11 code. Buy RINNAI

    • Remember to flush annually.
Size: 7.0 GPM Color: Gray
Replacing a different model of the same brand. All the connections matched without major modifications and installation was simple. Exterior mounting location. Looks to be durable. For the sake of warranty, I utilized a contractor.
