Okay. I have an A O Smith "energy saver" 50 gallon, 240V, single phase, residential electric water heater which has just sprung a leak. I am looking for a water heater that can save on energy costs while giving the same or better performance than my "lame duck" water heater. I will be calling Johnstone first thing in the morning and see what they say but I thought I would like to pick the brains of my friends first. Price is also a consideration.

By the way, the model# is EEST 40 917. Google keeps telling me I am wrong but my water heater insists that its the right number
