Rated 4 out of 5 by from Large water heater needed for large family! I purchased the water heater from a local Winnelson franchise. Unfortunately, the unit was damaged in their warehouse or while being shipped to the retailer. Aside from the shipping issues, we have three teenagers and appreciate the capacity!

Rated 4 out of 5 by from So far so great! Installed my new water heater four days ago, installation was a snap and heater was up and running within a couple hours. Within 30 minutes of completing install we had hot water and have yet to run it out(family of seven this says something). Compared to our previous water heater this one is nearly silent when the power vent is blowing, a vast improvement over the old one that would wake me in the middle of the night. The only concern being that when it showed up, while the shipping box was fine, the heater itself had some dents in the exterior sheet metal, they are at the bottom up against a cement wall, so long as it works I really didn't care however I think when selling a premium product a little more concern should be shown by the factory in what it lets out its doors. All in all though, it seems like a winner.

Rated 5 out of 5 by from Replacement of AOSmith 75 Gal tank after 11 years I purchased this tank 8/27/2014 as a replacement for the AO Smith 75 Gal tank that was installed when our Town House was build 11 years ago. We felt that that tank performed excellently for 11 years, so it was a very easy decision on what to replace the old tank with. This is basically the same tank which has been updated after 11 years. There was nothing wrong with the tank we replaced, but I felt it was probably getting near its end of life cycle.

Rated 4 out of 5 by from 2nd one This is our 2nd AO Smith water heater. First one lasted 12 years with "do it yourself" easy maintenance, but rusted out on the bottom and developed a water leak. This new one was installed 4 days ago, so we'll see how long it lasts. Looks cleaner and we like the newer safety feature with the higher side air intake.

Rated 5 out of 5 by from A Safe and Luxurious Option I have never heard anyone complain about having 75 gallons of hot water available in a traditional water heater. I keep the temperature low (about 120 degrees F) and the water heater just idles. I have plenty of even-temperature hot water for my long hot water runs and my jacuzzi. No scalding. A real luxury. Expensive upon purchase, but I think the extra cost spread out over ten years is worth the luxury and convenience.

How it Works

Gas water heaters heat water by burning either natural gas or LP (propane). Gas water heaters need a source of air and also need to be vented properly. Cold water enters the water heater through an internal “dip tube” which forces the cold water to the bottom of the tank and pushes hot water out through the outlet connection. This arrangement provides the most hot water for a given tank size. Most gas water heaters use a pilot light. The pilot light on some models also generates the power needed to operate an electronic gas valve. When cold water enters the tank, the temperature sensor on the gas control tells the main gas valve to open. Gas flows to the burner where it is lit by the pilot light. The air needed by the burner is supplied by the room where the water heater is installed. The exhaust gases are vented to the outside. When the proper temperature is reached, the main gas valve shuts off. Because water can corrode the steel tank, we glass line the inside of the tank and install an anode rod to help reduce corrosion. The temperature and pressure relief valve is a safety device designed to open if the internal temperature or pressure of the tank exceeds certain limits. Water heaters should be large enough to provide adequate hot water even when temperatures are cold and household demand is greatest.
