The whirlpool 9 year guaranty 50 gallon electric water heater is great. This unit remembers how and when you use hot water. With this knowledge it does not heat until just before you usually use hot water. This is a real cost in electricity saver. It expells very little heat outside of unit. It was very easy to install. Whirlpool is a very trusted band, and very pleased that I decided to choose the Whirpool water heater. We uses a lot of hot water, and we never run out of hot water. When we first installed it , the water heated up very fast.
