January 1, 2023 — Gus74 · Review provided by aosmithatlowes.com — 4/5

Although I do not have much History with this product yet, I am pleased with it's performance thus far. I and my wife raised five children, (4 of them girls), and we had an A.O Smith 75 Gal. water tank installed in this home shortly after we bought it, and got 31 years service out of it. It finally sprung a leak, and we had our Plumbing contractor look into a tankless, which were not on the market when we made our previous purchase. He still recommended A.O. Smith for it's reliability. We have been very pleased with it's operation. It does take slightly longer for the hot water to warm up at the different faucets and showers located throughout our home, but I'll trade that anytime for limited hot water. Another big plus is how little space the unit needs compared to a traditional water tank.
