Product came installed on a new home we purchased. Its nice because it saves space by being installed on the exterior wall of the house. My only gripe is it takes quite a while for the hot water to make it to the faucets.. Slick3844. Sun May 31 2026

This heater can put out some heat!! I set mine at 60 degrees and it stays 70-80 degrees in my well insulated small home. It is NOT a wall insert - it mounts in the floor- I purchased it to mount on the wall and then had to call Wayfair because it does not mount on the wall as advertised. You can see the holes I have had to fix in my wall because this heater does not mount on the wall.. Lisa. Carthage, NY. Mon Dec 18 2023

The Rinnai tankless H2O heater works as advertised-- water gets heated quickly, and with the wi-fi controller installed, I can use my smartphone or tablet to control aspects of it, i.e. enabling hot water on demand and setting the temperature of the water. However it is the APP that needs some work. There is *minimal* information on the app's features and how to use it. It's a great idea that just needs a little work to make it truly useful..

We had to have these parts for our new heater but couldn't find it anywhere. Without it, we were in a mess. The one we tried to order before Wayfair purchase, was smashed in transit. This arrived within 2 days and 2 days later we had heat!. Michelle. Walsenburg, CO. Tue Dec 20 2022

The sleek, compact size allows you to install the unit wherever you want, including under a sink or in a closet.
