Great size for small spaces, check for damage

We bought the tank ourselves to save time and money. The box had not been opened and there was no signs of damage on the box. Upon opening the box we discovered the top, back edge was crushed in. The box was in great shape, so it had to have happened in the factory. They packed it anyway! Our Plumbers were on a tight schedule. They assured us it would not affect the functioning, so we let them install it. Buyer beware, open the box before leaving the store.

A Lesson in Patience

Would Not Recommend

First one I brought home from the store was damaged at the factory. Box was perfect but unit was crushed, probably by a forklift. The guys just boxed it up and sent it out. Lowes got me a new one after lots of work to get it moved with help of $100 an hour handyman. Installed the new unit with help of $100 an hour local handyman. but it wouldn't heat. Called the Lowes but they wouldnt take it back because it was more than 48 hours(this was on a weekend) Could not afford to keep the $100 an hour ...

nipples are taller

I purchased a replacement water heater identical to the previous. The nipples are taller than the nipples on the water heater being replace and the water heater could not be used.

Hidden Dent

I purchased this online and my local Lowe's was out of stock and it would be a week before they got one. After getting it in place and installed I removed the paperwork and manual taped to side of water heater. I noticed a huge dent behind it. I called Lowe's to get it exchanged and I was told they they would not exchange it because it was removed from box and not leaking the only thing they would do is offer 50 dollar credit. I called the Mfg AO Smith and they said there is nothing they can do...

Powerhouse mouse

Would Recommend

Install was relatively easy, really need to run the hot water side a lot before you turn it on. The heater is so much better than our old one we feel like we could easily turn it down it gets so hot. The unit puts out 125° water from the factory settings. The water stays hotter longer than our older unit too, which must equal to money saved in the long run.
