Just Installed... HOW Can I Rate the Product?

Would Recommend

Pick-Up Was Timely and Painless. Self Installation was without any problems. Just filling the tank before turning on the Water Heater... I'll let you know how it goes from here.

Quick, Quiet, Efficient

Would Recommend

I have personally installed hot water heaters before in other homes we owned and I've always used AOSmith. These newer models are awesome, it heated the water VERY quickly with no noise (I assume due to the thicker insulation) and is very efficient at maintaining the set water temp. Recommendations; before installing research and follow instructions and for hardest part plan how you're going to dipose of the old one which is much heavier due to sediment.

Replaced one just like it that was 23 years old

Would Recommend

We replaced this AO Smith hot water heater with an AO Smith that was 23 years old. That said, it sems like a brand to be trusted. We hope this new one lasts as long.

Simple, works fine

Would Recommend

Everything is fine except it really should say not to remove the heat shielding in the cold and hot pipes. It was the standard for decades to remove the plugs from these, but now they don’t have plugs, but heat barriers.
