Satisfaction on A.O. Smith Low-Boy

Would Recommend

I have used this type of water heater for years and noticed the height increased by half an inch. Our home has the furnace above the water heater and has limited space for any more increase.

Satisfactory

Would Recommend

I just had this water heater installed today. I am sure it will prove to be satisfactory in what it is supposed to do. I trust the installer and he handled everything perfectly. So yes, I am satisfied.

Tank itself is fine, their incompetent delivery..

Would Not Recommend

Tank itself is good I'm sure, but my wife watched the guy literally drop it outta the back of his ford escape n theirs a huge dent in the bottom 😡 they need to actually have their own delivery service n not just hire incompetent dudes w a suv to deliver stuff... I paid almost 700$ n got a damaged product..
