Installed this beast a few months ago and have the following feedback: 1) It's heavy. If you're used to the standard 40 gallon heater, this thing is much heavier and larger. 2) In spite of having three showers and a big jacuzzi tub, a - it has never run cold. 3) The default temperature setting may convince you that it's not heating properly, crank it up a notch and you will be fine.
It has also been inexpensive to run.
