Rinnai High Efficiency Tankless Water Heater - 130k BTU - 6.5gpm is rated 4.0 out of 5 by 28.
Rated 2 out of 5 by from Wastes Water I purchased a new home and this tankless water heater came with it. As soon as I can afford to replace it I will. The default setting is 140 degrees. I do not have children in the house and like my water a lot hotter than that. Changing the temperature of the water is difficult at best. It requires you to change the dipswitch settings in the right combination. The problem is that if you change it from 140 degrees it will not give you a consistent temperature. Also, it takes forever to get hot water so you end up running a lot of water down the drain. In Arizona wasting water is a sin. Sure you never run out of hot water, but if you're single or frugal this isn't an issue.

Rated 3 out of 5 by from Some issues. From time-to-time, the water in the shower will just go suddenly ice-cold. Not pleasant at all! It will not come back hot for about 3 or more minutes. My installer, a very experienced plumber who has installed dozens of these is baffled. He's been on the phone with Rinnai tech support many times. I don't think this is a common problem. We really want to resolve this issue. It only started happening after about 6 months. Prior to that, it worked perfectly.

Rated 5 out of 5 by from Rinnai RUCS65iN My unit has been operational for approximately 2-1/2 month. The unit is mounted inside the house with combustion intake and exhaust air provided via external venting. The unit is operating flawlessly. One aspect is the water temperature is surprisingly consistent regardless of other activity in the house be it either additional hot or cold water demand.

Rated 4 out of 5 by from Second purchase Works great but pricey. Need to service regularly, which I did annually. Not difficult but must be done. This is our second Rinnai and am disappointed the first only lasted 8 years before the heat exchanger cracked. Rather than replace the part which Rinnai did cover, we opted to purchase a whole new unit.

Rated 5 out of 5 by from Great Quality and Efficiency Like all tankless water heaters, it takes a bit of time for the hot water to come through when turning on the faucet for the first time when it hasn’t been used for a while. I haven’t found that to ever take more than 20 seconds or so with my Rinnai, so I’m very pleased! So far, it’s been very reliable.

Rated 5 out of 5 by from A great Energy Efficient Hot Water Solution for ou We have been in our new home for just about a year now. Our Rinnai hot water supply never runs out of hot water, we like to shower and bath in the evening and that used to cause a problem if theses weren't spaced out. Now it really doesn't matter as this unit can keep up with our constant demand.

Rated 4 out of 5 by from More than a month, and its working good I am using this tank-less water heater for more than a month without having any issue. Its good for small family size. However it takes some time to send hot water, if you are OK with wasting water for initial few minutes during winter, then its right product.

Rated 2 out of 5 by from Rinnai good, tankless not very friendly If you're wanting a tankless water heater, Rinnai performs as expected. However, the tankless technology results in a long wait for hot water. And it doesn't supply hot water to modern washing machines, which tend to use water in small bursts.
