better than tankless
This tank replaced a 75 gal HWH in a 4500 SF house with 3 cloths washers where running out of hot water was a daily occurrence. Since this HWH was installed we have never run out. I have a tank-less in a summer house...what a pain. The newer tank-less have serious quality issues and customer satisfaction. This AO Smith does NOT have the "hot water sandwich" and you don't have to worry about enough flow to turn it on.
