  • Dreaded E8 error code. My fix
Size: 24L
Very easy to install, we had a problem about week two of using the heater, kept getting E8 error code and only able to use one faucet for a very short time. Look up the code in the manual and it says exhaust vent restriction. So i changed my outside return to a bigger one. Same problem. So then i change the 3” exhaust pipe as recommended in the book to a larger 4”, still have same problem. So now i know its not anything i installed that was causing the problem. This was a few month trial and error. So i put everything back to 3” exhaust and left the large aluminum return. Now im convinced the heater isn’t actually having exhaust problems but starving for fuel, since i tapped into my central heat and air line. I had roughly 6’ of 3/4” gas line T off from my unit to the water heater. So i upped it to 1” to get more volume for the heater to use. Still didnt fix my problem. Still E8 and only 1 faucet. By now im ready to rip this thing off the wall and buy one from local supply store. I wanted to take it apart and see if maybe there was a bad sensor or an obvious issue under the panel. Didnt see anything other then some thermal sensor touching the flame box, moved it off and secured it, still same problem. My last resort before i ripped it off the wall, i wanted to look down into the exhaust of the unit itself. And viola i see a chincy metal grate, push on it with screw driver and it pops down, i bend it and pull it out. Put exhaust back on, outside return has its own grate so dont need the factory one. Unit Works perfectly ever since can use as many faucets as i want and as hot as i want. ... show more

  • E1 and E8 errors constantly after 7 months of use...
Size: 24L
Bad purchase on my part trying to save some money... it was installed correctly and cleaned as it should be. However after about 7 months of use it throws e1 and e8 errors back to back to back while trying to use sink, shower, you name it. I should have spent 100-150 more for a better unit. Now I have to buy another one soon. It does save gas and water when it works... was great the first 6 months as well. Take it for what it's worth before buying!!!! Good luck ... show more

  • Great water heater!
Size: 24L
We installed this in our cabin up north and absolutely love it. The install was easy and it works great. We are able to have two separate showers running at the same time without running out of hot water. Great investment!

  • Does the job at half the price
Size: 24L
Consistent hot water, easy installation, it just works. At about half the price of other brands, this unit has been excellent so far. Installation took just a few hours and it fired right up. My only gripe, I can’t imagine more than one source of water being used as it drastically cuts pressure when multiple points are used, but very satisfied none the less. ... show more

  • Seamed okay 👌
Size: 24L
This is quite the piece of equipment but before you buy check with your gas provider, I personally hooked mine up but it wouldn’t work so I had a professional come out, he said he couldn’t Even touch it because it isn’t up to code , with this particular model you would have to wall off your water closet door and make an outside door so that it’s not considered a part of your living space, like my propane furnace has it would need a separate air intake and separate exhaust which would be fine inside the water closet where the existing electric water heater was, I’m sure it would have been alright if it were up to code but didn’t work for me. Like I said check with your gas provider first. The propane expert said if he came out and saw that the homeowner had hooked up a separate device without first getting permission from the gas company that they would have shut off the gas and shortly after promptly remove both tanks and that would be that. So do yourself a favor and check with them first if you’re a professional handyman and can do it yourself, if you hire a professional, the first thing they will do is contact your gas provider for permission 👍 like I said if it had a separate intake and exhaust it would have been fine but please do yourself a favor and check with your propane provider first, they can give permission or say nope not up to code. PS the propane professional said he’s had a Rinnai for 19 years and that Rinnai is the beast of tankless systems, he services it every year to clean any sediment also has a before filter but 19 years is a good testimony for me , I like those odds ... show more

  • Buyer Beware!!!!!
Size: 24L
Do not buy this water heater from this seller. The first one had a damaged package and inside the heater was rusty, dented and broken. Returned that one and was sent another one. Unfortunately I had to wait to get someone to install the replacement water heater. When they installed it, it would not stay on. It kept clicking off. It had all types of error codes pop up. The first return window date was 01/31/25. I figured the second heater would have a different return window date. When I called to return it, I was told the window had closed for returns 3 days ago and there was nothing they could do to help me. Now I am stuck with a water heater that cost me almost $600. The agents that I spoke with from Amazon were totally useless. They were no help at all, just kept repeating, sorry, sorry, sorry. B ... show more

  • Cold weather issues with water flow sensor
Size: 24L
We live in South Carolina which has only a few below 30 deg F nights. Unfortunately I've had two failures of the water flow sensor which Marey says "is possibly due to cold air coming down exhaust vent" for our two yr old unit. Our exhaust vent has vent flaps to prevent air flow when not in use and I let out faucets drip. I would not recommend this unit to anyone. I'm a retired BSME and have worked in maintenance. I have installed insulation around cold water water pipe also. ... show more
