Not too sure since this is my second unit.

I originally purchased one on 2/1/26. It was installed 2/2/26. I had no hot water until 2/12/26 when they installed a new unit!!!!

AO Smith was my choice

 Would Recommend

My old Hot water heater made by GE but was 18 years old but still producing hot water like it was new. I was required by my homeowners insurance policy to replace it because of age. I chose AO Smith because of historic quality. I installed it 2 hours ago and I now again have hot water. Iam in process of sending photos and proof of purchase to my insurance company.
