Love tankless hot water. Installed it 6+ months ago & left town for a weekend. Upon return found no hot water. Rinnai jumped with my local gas company to trouble shoot. Found they could not quickly repair the unit, so overnighted a new unit to be installed the next day.

The best on demand water heater. Never run out of heated water. Very efficient too.

"Very pleased"

We've had our Rinnae on demand water heater for about a year and have not had any issues with it. We had one in our last house and had been very pleased, so when we needed to replace an old water heater in our next home, Rinnae was our first choice.

"Exceeds expectations. The tankless system eliminated several issues with our 2nd home and our being away for several weeks at a time."

Owned less than a year installed in a 2nd home. Meets our needs, no issues with having sufficient hot water and easy to turn off/on while we are away. Exceeds expectations.

Likes: Water warms up quickly, no problems with the system (have had it for a year) Wishes: I wish it came with a backup battery ot had a built-in battery. I purchased a battery separately for those occasions when we lose power.

Replaced our boiler and tank water heater with a combination Rinnai unit in our previous house, very happy with it. Moved a year ago and replaced the tank water heater in the new house with an on-demand Rinnai water heater. Very happy with both units.

Have had the Rinnai for 5 months. Like the almost instant hot water. Easy to program with the Wi-Fi control. It meets my expectations.

Takes too long for hot water…Instead of a crossover due to the size of home tech came out to install add on part.
