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. The Energy Saver is equipped with a self-powered gas valve that requires no external power source and provides improved temperature and accuracy. A DynaClean dip tube helps maintain efficiency by reducing lime build-up, and a tamper-resistant brass drain valve increases reliability and safety.
I have just replaced our A.O. Smith hot water heater that was installed in our house in 1994. This hot water heater did what it was supposed to, make water hot. The tank finally rusted out and we replaced it with a local hot water heater distributor's make and model.
"Bad hot heater"
This is the worst water heater that we have ever owned. The plumber has to call the company before he can do anything, on account of the warranty. The plumber knows what is wrong but the company won't okay him to fix it. Never, never buy one of these hot water heaters.

"Very satisfied with this water heater"
Have low profile 53 gal. Heaters installed 15 years ago. One is needing replaced. Other one still ticking fine. Very satisfied with this performance.
There are very few comments about the Energy Saver water heater on HVAC forums. A consumer on applianceblog.com thought his 6-year-old Energy Saver may need to be replaced because of a lack of hot water, but was advised to change a heating element, which fixed the problem. A consumer on doityourself.com stated that he'd had no issues with his 9-year-old Energy Saver but wondered if he should drain it for maintenance. He was advised by other contributors to leave it alone because draining a tank after so many years could cause other problems.
