Would Not RecommendInstalled 7/1/26 Had to drain tank 4 times to get rust and sediment out. Used two days and stopped heating, tried to reset, no luck. Returned to Lowe's for another one. Told Lowe's the next installation would be on them. So far so good. Stay away from this brand.

12 yr model costs more, but worth the money. Half the cost of replacing a tanked water heater is the labor/service charges, so buy a reliable brand (A.O. Smith) and buy their longest warranty model. I've been using their pool heaters and pool pumps and my contractor brothers said hey, they now make home water heaters, with the same quality parts and assembly as their other products. Thumbs up to A.O. Smith.

This water heater has been working perfectly since I had it installed. I have noticed consistent hot water. I had to turn the temperature down because I felt in medium heat, it was to hot.

Lowes - scam
It is a scam. They sell the item what is not exists. I placed the order and week later on the day of delivery i received the massage "could not deliver". I went to nearest Lowes and associate tried to locate the item. It was shown that delivery is coming from Colorado Springs store. After contacting that location we found out that item is not in stock.

Got the Job Done!
Would RecommendOur old water heater (25 years old!!) was done. Finished. It had nothing left! So we looked at various 40 gallon water heaters and settled on this one. It seems to be working great, no complaints. Would recommend.
