Energy Star is a label that means nothing to you.
Manufacturers use energy-star label to promote a product as a money-saver.
They can put an Energy Star label on a giant 10,000 square foot house, and you know that cannot be the truth that a large house saves energy vrs a smaller house.
Energy factor, (energy factor/ not energy star) on the other hand, is a comparison measure how efficient the water
heater uses energy to heat a gallon of water, when water heater is
EE3J50RD045V has energy factor of .59, which is completely typical and ordinary for electric water heaters.
The EE3j 50 gallon is an ordinary electric water heater, with ordinary average .59 energy factor rating, so electricity to operate this water heater is same as any other typical 50 gallon electric water heater: it will cost $35-45 a month depending on incoming water temperature, hot water use, thermostatic setting, electricity pricing, and whether you operate heater at peak pricing, etc.http://waterheatertimer.org/9-ways-to-save-with-water-heater.htmlhttp://waterheatertimer.org/How-much-does-it-cost-to-run-water-heater.html
The most important measure of water heater cost does not have anything to do with Energy-star or energy-factor.
The most important measure is total cost of owning and operating the water heater.
So if you spend $100 more to purchase electric water heater with slightly higher energy factor, then it will not pay you back. The difference will be $2 to $4 per year.
All costs are energy.
The total cost of operating water heater includes purchase price, installation cost, cost of repairs, cost of parts, whether you can fix it yourself, expected life of water heater, and replacement cost.
Every water heater has expected lifespan, and will not have resale value except current price of scrap.
Electric water heaters cost more to operate per month than same-size gas water heater.
Gas water heater might cost less over the life of water heater, but gas water heaters are increasingly expensive to repair, and increasingly more complicated, and cost more up-front to buy.
Electric water heaters cost less to buy, are easy to install yourself, are fully repairable by homeowner using generic off-the-shelf parts, and can be made to last many years by keeping tank clean and replacing anode rod every 2 years.
You can make ordinary 6-year electric water heater from box store last almost indefinitely.
Avoid electric water water heater that has electronic controls.http://waterheatertimer.org/Clean-sediment-out-of-water-heater.htmlhttp://waterheatertimer.org/Replace-anode-rod.html
