What Customers Are Saying
The water heater has several positive features, including an electric pilot light, automatic flue damper, and quick heating capabilities. Many customers found it easy to install and reliable so far.

Overall, the water heater generally performs well and meets most customers' expectations for quality and energy efficiency.

This is a good atmospheric water heater, but changing a couple of things could have made it even better. First: This has a nylon drain value on it. This is a $1100 water heater, put a brass drain value on it. Using a nylon valve conveys that this is a base model. I hope that the nylon valve holds up as I do drain our water heaters intermittently to get some of the sediment out of them. Second: This water heater has a pilot light. It has a flue damper to save energy. I paid significantly m...
Quality Hot Water Heater
My last AO Smith worked solidly since 2008 - far exceeding my expectation. I decided to replace it now with a new AO Smith Signature 100 for efficiency and to avoid system age related water leaks.

Great heater easy to check status.
Had to replace my AO Smith heater that was installed 18 years ago. I hope that this new one lasts as long. The control panel has lights that let you know if the unit is working or having a problem.

Flammable gas sensor
I don't think there is a description that this water heater comes with a flammable gas sensor. At startup, there was an error message that the gas sensor was activating, which prevents the burner from coming on. It wasn't. There is a way to reset the water heater to make this error message go away and successfully start up the burner, but the manufacturer doesn't want to provide that info unless you call one of their technical specialists. So maybe a water heater without a flammable gas sens...

Easy Installation -done in 5 hours
One of the items I had been meaning to replace since my old hot water was about 18 years old. I had replaced my sons hot water heater 7 years ago and that took a little bit longer than this one. This was easier and I did it by myself. Most of the time was spent emptying the old heater.

DO NOT BUY
Brand new Signature 300 doesn't work right out of the box. Day 5 of cold showers. Been going back and forth with tech support for days. They had to ship new gas valve, burner & igniter to replace brand new components. What a nightmare.

Doesn't work, right out of the box
Day three with cold showers. Brand new Signature 300 water heater from Lowes. Pilot would not stay lit. Went back & forth with tech support for hours. Finally determined the problem is a defective igniter assembly. Going to be another day before part arrives. Buy a different brand. My GE lasted 17 years.

Great features
This is the second one I’ve had installed now and it’s my favorite. I love the electric plug for the pilot light. It never goes out on me like the previous one did.
