What is an energy factor for water heaters

An energy factor is a measure of how efficient an appliance, such as a water heater, is in converting electricity or gas flame to useful heat. 

 Casing insulations material makes a difference. But the biggest factor is the heat exchanger construction. Typically there are two options- copper and Stainless Steel. Copper heats up much quicker than Stainless Steel but it can corrode over time which means the owner has to replace it eventually. Stainless Steel doesn’t corrode but takes longer to get hot, meaning more wasted electricity and cold spots.
