Nothing, same burner. The Elite actually refers to the family of burners Carlin has named them. The 3 residential models of the Elite "Series" are EZ-1, EZ-2, and (you guessed it) EZ-3. The main difference is the maximum firing rate they can handle. I believe the EZ-1 can fire 1.65 gallons per hour, which will handle all but the biggest homes. The 2 and 3 EZ's are mostly light commercial, but I bet some rich guy with a 8000 sq. ft house might need one. That's an oil account I'd want!!Originally posted by traron
What is the difference between the Carlin Elite and EZ burners?
