AO Smith Energy Saver Water Heaters

AO Smith Energy Saver Water heater Overview

The A.O. Smith Energy Saver is a series of natural gas and propane water heaters designed for manufactured homes. Energy Saver water heaters are available in 30-, 40- and 50-gallon capacities and are available in either standard or direct vent models. A low NOx, Green Choice burner reduces emissions by up to 33%. All models feature Flammable Vapor Ignition Resistant (FVIR) technology, which prevents against accidental ignition of flammable vapors.

AO Smith Energy Saver Water heater Reviews

"Faulty equipment"

1.0 rating
Very Unsatisfied

Approx year old. New built home, rust running down the front from a leak, leaking in the pan, having to vacuum water out of pan multiple times, now leaking internally sufficiently to kick the breaker. Having it replaced today. Will not be an ao Smith. After reading the reviews, I know it will be useless to even attempt to get anything back on it. Lesson learned.

I've had my electric hot water heater since 1995. It lasted for 22 years; way beyond the warranty period. Just purchased a replacement.

"AO Smith the worst water heater ever"

Very Unsatisfied

Never buy an AO Smith product. They are all junk. Have a 10 year warranty on mine and developed a leak in 5 years. I see the warranty requires us to pay installation and return of water heater to dist. What a joke.

"Awesome electric water heater"

5.0 rating
Very Satisfied

My water heater has taken care of my family of 7 like a dream, a perfect gem for 25 years and never, ever, ever had a problem. Finally it is leaking and a new water heater is needed. What a flawless product. I will swear by this company to any and all. If you have to pick, AO Smith is a secret gem and I promise you won't be sorry. It's a perfect product to be sure.

"5 1/2 years & busted!"

1.0 rating
Very Unsatisfied

We built our house and moved in less than 5 1/2 years ago. There are only 2 adults and two small girls in our family. We also travel so water use is not maxed out.Our 75 gallon tank is already extremely corroded, leaks water and now doesn't work. We have to completely replace it. When my husband was talking a plumber about it he knew without being told it was an A.O. Smith tank!
