    Rated 5 out of 5 by from We're pleased! I love the new cut-off/cut-on valves features! Our old water heater did have them, very handy. It's set at the recommended temperature (120D) & that seems to be working just fine. It was only installed last week, so it may be too early to review, but so far, so good, & we are pleased.

    Rated 5 out of 5 by from Quiet while heating water. Heats water quickly. Very nice water heater. Quiet and efficient. Heats up the water quickly. The only thing I found lacking was a parts / maintenance instruction list, for replacing parts. I would like to order at some point in the future, an anode replacement sacrificial rod.
