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. 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.

"20 years of service"

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"

Very Unsatisfied

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.
