Customers are mixed about the quality of the water heater. Some mention it's very efficient and provides nice, everlasting hot water. They also say it'll provide hot water for showers and baths, with no issues. However, others say that the front panel is dented, the black seals broke, and the factory packaging is flimsy.

Customers like the heat of the water heater. They mention that it provides endless hot water, immediately, and easily. They say it can supply the hot water needs for both showers, the kitchen sink, and the dishwasher.

18 customers mention14 positive4 negative

Customers like the size of the water heater. They mention it takes very little space, is very helpful regarding freeing up storage, and is big enough to handle all their needs.

Overall very pleased. This unit is rated at 8

Overall very pleased. This unit is rated at 8
I bought this unit to replace my R85i from Rinnai which had a cracked heat exchanger. Most places wanted around $600 for a new exchanger, so I opted to just buy a complete new heater. Mostly because with the old unit, the electronics had been exposed to water and even if I replaced the exchanger and it worked, for how long? You get the idea.This unit is ALMOST a direct drop in replacement for my older R85i, huge kudos to Rinnai for keeping the form factors nearly the same - this makes replacing an older unit that much easier, THANK YOU RINNAI. There are some differences though. The chimney diameter is different by about a millimeter... meaning you have to buy a new one. Slightly disappointing. The mounting holes lined up for the most part. The ending position of the water and gas lines was virtually the same. This saved me a lot of time as I didn't have to do much to the plumbing. I did add a 3 core filter system though and had to re-plumb that. Also I used the steel braided lines going to the hot/cold as you aren't supposed to run pex directly to an appliance. (I did not install the old unit).Overall very pleased. This unit is rated at 8.x GPM and my old unit was 9.x GPM. Can I tell the difference? No. This IS a condensing unit though, it is much higher efficiency than the old unit. The old unit was something like 80%, this one is something like 95% (don't quote me, look it up). Because of this there is a condensing line you need to plumb. You HAVE to do this, do not just cap it and let the water pool, it will flow into the electronics of the box and ruin it.I'm told if you want to go higher that 120F you need to buy a separate controller. Honestly not an issue for me. I set it at 120F and forget it. My old unit was set at 115F. I can't tell the difference. Really, I can't think of a reason you would need/want 140F tap water anyway. YMMV. Here is a photo of my setup (incomplete) with my 3 core water filter. No, I did not install the gas line - some other boob did that. My understanding is that the flex gas line is only supposed to be used for the final 36" to an appliance - apparently the previous installer got that backwards? I am going to re-do the gas line at some point...
