Customer Reviews for Rinnai High Efficiency 6.5 GPM Residential 150,000 BTU/h 44.0 kWh Propane Exterior Tankless Water Heater

Appears to be very energy efficient, I have had product for 6 months, so far so good

This Rinnai product meets all expectations we had!

Instant hot water and never runs out! We've had this system four months.

Once you have hot water it says hot. But it takes 2 minutes 20 seconds to get hot water in bathroom. We have had it 1 year. It does not meet our expectations. We we from a propane regular water heater to tankless and the vendor did not explain you need electricity for the water heater to come on and work. Would not buy another tankless!

Excellent quality water heater, works perfectly. Absolutely no complaints so far.

love we don't have to waste gas by keeping 80 gal water hot all day......love on demand hot water love the savings we saved 200. gal gas last year this is my 3rd one been using tankless 3 yrs now exceed my exaptation's don't change a think

I got the error code 11 after a couples days..

This product is being used to provide hot water to a "Granny" unit separate from the main house.

The delivery was quicker than they estimated. Had it installed. It heats water fast. Very pleased.

Love the fact that I never run out of hot water. Only dislike is the length of time it takes to get hot water to the bathroom sink furthest way from the heater unit.

Replaced an older, larger, and less efficient unit. Very satisfied.

Dislike waiting minutes for hot water. Yet, like lower electric cost without hot water heater.

Excellent quality and reliable. I've had 2 of them for 6 years and they have been wonderful. Endless hot water. I do suggest you install them downstream of a water softener to keep water deposits from building up internally.

It’s a great product!

worked perfect right out of the box.

System appears to work well, but instant hot water is not actually accurate. The further away you get from the unit the longer it takes...minutes in some cases!

Had it 4 months. When it gets into the 30's in Florida, it quits working - that is 4 times since we've had it we have had no hot water. Called the plumber that installed it told us good luck and blamed it on the propane company. Propane company blamed it on the plumber. So here we sit with a water heater that only works sometimes.

Everything about this unit is fantastic. The one area for improvement is the external controller. Ya'll really could have made it 1) Easier to hook up with connectors that don't require stripping small wires. 2) Get ride of the external controller! This is 2021, let us use our smart phones and an app. Why would you make an external controller that's not weather proof when the rest of the unit already is? Other than that, I love this unit, very functional, reliable and never runs out of water, even when I fill a hot tub!

Yes takes a little while for kitchen sink water to get hot probably about 1.5 min..

The remote thermostat is perfect, the outdoor unit looks good and works great

No tank to store water or the possibility of tank failure Had it installed approximately 6 months

Excellent production of hot water, never runs out during the course of a day of heavy use.

Works beautifully even when multiple showers are in use.

The first Renai Tankless hot water heater I bought didn't last as long as I thought it should. Had to replace after about 10 years.

This is a good covenant water heater mounts outside and works really great. Installed about 2-3 months.

There is no reduction in flow of hot water. It is an excellent system.

Has worked flawlessly so far, uses very little propane.

Installation was simple. Works extremely well. Very clean looking hanging on the house. I highly recommend it.

We lost our house to a fire which also had a Rannai tankless water heater. I would say other than saving money, the best feature is hot water when you need it! Now in our new home we are experiencing the same dependability! I would buy it over and over.
