So far, so good...

Have had the new unit foe under a week, but it is preforming as designed.

Direct replacement for the same model from 13 years ago!

Easy drop in replacement for the same model that failed on me after 13 years. Plumbers wanted to replace it with inferior products for over $9,000. Thanks to SupplyHouse swapped it out myself for the cost of the unit and got better quality

RECENT INSTALL

I just installed and so far I'm happy. The only issue is the noise/vibration when it is running. I added isolators to try to reduce the noise, but reduction was minimal.

Lovin The Tankless

We bought this product a month ago and the ladies (and family) are loving the endless hot water in their new shower. A few hour and a half showers and lovin it. Able to run multiple appliances and still shower with hot water. Takes just a little longer to get the hot water flowing upstairs but well worth it.

Great product

Purchased this to replace a water heater that was a tank. So happy with extra space and super clean looks. Oh and it works awesome !!

Water Heater

I bought a new water heater and had it installed today. It seems like a very efficient water heater.

I like it

Like it

Great size

Just got my First Tankless water heater very excited so far I love it.

Excellent equipment!

Our other tank went out December 24th leaving me with no hot water and company coming for Christmas .

Maybe the finest product I have bought in sometime

Recently installed a walk-in tub from American standard. Takes about sixty gallons of hot water to get the full relaxing experience with hot water. Immediately found that a sixty gallon storage hot water heater would not supply enough hot water, much less service other appliance needs such as laundry at the same time. The tankless units made by AOSmith supplied the bath with a continuous supply and everything else in the home ,too. Factory setting at 120 degrees was perfect. I cannot say enough about the ease of installation/ operation . Unit is the highest quality throughout. I went all out and bought the 199,000 BTU heater.

Strong heat - error code issues

This unit heats well, but we have encountered one recurring error code issue. I'm not sure what the cause is, so I'm not going to say this is a bad heater. Overall, I'm quite happy with it so far.

warranty

Worst warranty out there of any water heater brands by far... i would never recommend AO Smith to anyone

Will buy for another house

Good product for this money. Work perfect.

Great unit. Easy to install.

I installed the unit and it went in without any issues

Heats well!

This is my 2nd one...it was under warranty the 1st had a leaking heat exchanger.

New water heater

I bought this new water heater due the old good not get parts for it it was a easy to install

Tankless Water Heater

I went to register my Propane Tankless Water Heater and I could not find my model on the dropdown box. My Model is AT1-540H 101. Hopefully if I checked the wrong dropdown box you will correct my registration

Easy to install if replacing the old one

Bought a house ans the original water heater was leaking. Called AO Smith and they told me that the heat exchanger might be bad and it was still under warranty. So they sent me the "how to", to take it apart to verify. It was the heat exchanger, and they replied within 30 minutes of me sending the email with the picture of it broken and gave me a reference number and to take it to the local dealer to replace for free. They gave me the exact same one and I installed it myself with no issues.

My third unit in 12 years

Third home in 12 years so got to have tankless hot water heater only this one is Natural Gas. I wouldn't live without one since the first one I bought. Sorry it took me so long to register! Totally Satisfied Customer !!

Plenty of hot water...eventually.

Replaced a 50 gallon tank heater to ensure I have ample hot water to keep up with family showers, laundry, etc. Works great in that capacity. However, takes a lot longer than expected for hot water to come out after faucet is turned on.
