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.

Kenmore 66 Gallon Tall Electric Water Heater is recommended by Dominic
If you're used to a standard water heater, then get ready for something different. Everlast Pexan™ polymer dip tube, two Super Limeguard™ heating elements for superior resistance to lime build-up and a glass-lined steel tank with two large anode rods for superior tank protection all contribute to this unit's efficiency and durability. At 66 gallons, this Kenmore water heater will keep you in hot water.
