The propane water heater works well. Easy to install. Only problem is it costs $200 more than natural gas. What a rip off from the propane association.

Easy Peazy Pick-up
I asked for a little Associate assistance with the transaction and "Boom". An exceptionally talented Associate jumped right in and walked me through the process of picking up my Gas Hot Water Heater. They even loaded it for me in my truck. I was then on my way. Could not have been more pleased with the process. Oh!, P.S. I got a Pro to install for me. Took about an hour. Minimum cost.

New tank with a broken pressure relief valve
After installing the hot water tank, water kept coming out of the pressure relief valve. We had to go to a hardware store to purchase a new pressure relief valve and replace it. Major inconvenience and had to spend more money. Works great now.

Buyer beware! A.O. Smith warranty is a NIGHTMARE!
I wouldn't even give it 1 star if I didn't have to in order to rate it. My husband and I just replaced our 24yo A.O. Smith propane water heater on Tuesday. We figured our previous heater lasted so long, why not go with it again. We were without hot water for 5 days until we could find someone to install it for us. After installation, the pressure valve kept dripping out of the drain tube. We had hot water and were told to wait for any residual air to leave the hot water lines and it should st...

Broken Upon receiving
Hot water heater was damaged on the inside. Welds are crap. Do not buy it. This is poor quality and definitely would not recommend buying this to anyone.

Concerned
We purchased the AO Smith 50 gal propane water heater today (01/24/26) and after the plumber had installed the water heater he tested for gas leaks and his sensor indicated a leak in the control box. So he had to shut it down until we can determine the source of the leak. In the meantime we are without hot water.

Good, But Hard to Find Parts
Our water heater was installed seven years ago and it quit working. The warranty was for six years. The status light would not flash and the pilot light would not stay lit. A service company said it was the gas control valve, but they wanted too much money to replace it, so I did it myself. I could not find any part numbers for any parts on the AO Smith website, but I did get the valve part number off of the valve itself and found one online. It worked one time, then quit and would not work...

Lowe's Pick up
Lowe's pickup was a bit confusing as there new area has both a locker style pick up and a bulk area pickup. The key pads are on either side of the door way so if one does not work it does not tell you to check the other. The water heater was simple enough to install and works well.
