Easy to install. Only took an afternoon. Looks great compared to the 50+ year old that it replaced. Now just waiting for the weather to change to try it out. Expecting great results.

An Excellent Unit!
By Charles B
Roscommon, Michigan
Purchased 12/11/2020 |
Review Posted 01/07/2021
This is my first Rinnai product, which was recommended to me by one of our local HVAC businesses due to the 2-speed fan and multi-stage gas modulator. The installation and operating manual is clearly written and easy to follow. After completing the installation, the gas valve was opened and the unit plugged into the 120V outlet -- the furnace self-started and operated as designed. It does an excellent job of heating my well-insulated, long, narrow room (14ft. x 40ft.) evenly from one end to the other, even though the furnace had to be located on the 14ft wall. Very pleased!
There is one thing I would like to mention regarding the instructions. The flue installation instructions on page 10, in Step #1 has the following statement:
"Clearance to combustibles for the sleeve and flanges is zero inches."
Other than this statement, there isn't any mention or cautionary/warning statement in the manual about preventing the insulation in the wall from coming in contact with the flue, or if there is even a need to do so. Therefore, I called the Rinnai Consumer Line and spoke to a Tech Rep about my concern. He was very helpful and assured me that, due to the concentric design of the flue, with the hot exhaust gases being constrained by the inner tube and surrounded by the cold incoming air for combustion, there is no need to prevent the wall insulation, even the cellulose style commonly used in my area, from touching the flue sleeve as it passes through the insulated wall. With this re-assurance, the installation proceeded without incident.
I would highly recommend this unit to anyone in a northern climate.

Great Heater, love the timer feature
By David W
Findlay, Illinois
Purchased 01/01/2019 |
Review Posted 01/23/2019
Great Heater. Installed in our winter home in Quartzsite AZ. When we bought the place it had unvented Blue Flame heaters with smell all the time when burning. Replaced them with the Rinnai 8000 BTU, no more smell, just nice warm heater. Install took about 4 hours, just taking my time and doing it right. Nothing hard about it. I love waking up to a nice warm room, have our timer set on 6 AM, when we get up around 7 or so, it is toasty warm. We love this feature as we both like it cool while we sleep, but it is warm when we get up. The heater is easy to program and set.

Nice Little Furnace
By Randy L.
Baton Rouge, Louisiana
Purchased 09/03/2018 |
Review Posted 11/01/2018
I needed a winter heat source to complement my central heat pump and to replace an ancient floor furnace in my kitchen that has served that purpose for many years. Other than having to do a little wrenching and gas pipe work, the Rinnai was easy to install and set up. It puts out a lot of heat and is quiet. I have not had to run it much so far, though, as it's still pretty warm here in the Deep South.

Our old wall heater failed us and our plumber recommended this type of a wall heater. SOOO glad he did. It looks good and most of all it heats three bedrooms and an open living room and kitchen.
