My 20 year old State brand 80 gallon electric water heater is going bad finally. I went to big box store and found they no longer carry a 80 gallon standard type heater. Plumbing supply house said they are no longer making old style heater over 55 gallon. Something about government pushing for more energy efficient ways to heat water. Do any of you know of a source where I can purchase a new 80 gallon electric water heater?
