We Were First With Glass Coated Tanks
The superior time-tested Permaglas® coating process, developed by A.O. Smith, is considered by the industry one of the most efficient, long lasting defenses against the corrosive effects of hot water.
The process involves the fusion of glass to steel water heater interiors, using special ovens fired at 1600 degrees Fahrenheit. Over the years, we experimented with over 5,000 formulas. Only the best four are used in our water heaters.
We Produced The World's First Energy Saving Water Heater, The Conservationist.
The Conservationist concept, which makes it possible to produce more hot water with less fuel, is yet another example of the technological creativity that sets A.O. Smith water heaters apart. The current A.O. Smith Conservationist® models excel in every way residential gas and electric water heaters are rated. With energy-saving features so advanced they exceed the 1992 Federal Efficiency standards.
Our patented Thermotrap® System Makes Sure That Once Water Is Heated It Stays Hot.
Some water heaters lose substantial convective standby heat through the cold water inlet pipe and the hot water outlet pipe.
A.O. Smith invented a patented solution called the Thermotrap® System. It employs a simple, unique insulating ball concept that prevents heat from escaping into either the cold water inlet or the hot water outlet. Which means more hot water with less energy. At less cost to the homeowner.
Cold Water Inlet
When water is not being drawn, a "lighter-than-water" insulating ball (a) floats at the top of the cold water Thermotrap fitting, blocking heat
from escaping into the cold water line.
When a faucet is turned on, water pressure forces insulating ball downward (b) against a grid, permitting free water flow.

Hot Water Outlet
When water is not being drawn, a "heavier-than-water" insulating ball sinks to the bottom of the hot water Thermotrap fitting (a), blocking heat from
escaping into the hot water line. When a hot water faucet is turned on, water pressure forces insulating ball upward (b) against a grid, to permit free water flow.

We Invented and Pioneered The Anode Rod For Additional Long Term Protection
The anode rod is a highly effective, round-the-clock corrosion fighting system which utilizes cathodic action to attract the corrosive elements in hot water away from internal tank surfaces. Another A.O. Smith first, the anode rod has become an industry standard.
First Major Manufacturer To Put Easy-To-Roll Ring Bases On All 30, 40 and 50 Gallon Gas Models.
Broken or bent water heater legs are a thing of the past with A.O. Smith water heaters and their easy-to-roll ring bases. Positioning units, especially in tight quarters such as cramped closets, has never been easier.
We Make The World's Broadest Line Of Residential and Commercial Water Heaters
No wonder A.O. Smith is able to serve its customers better. Not only do we offer the highest quality, most innovative water heater products available anywhere, but the remarkable breadth and completeness of line makes A.O. Smith the natural source for virtually any conceivable residential water heating need.
