 By the early 1920s the Heater brothers were operating bulk plants along railroad lines, and following the Great Depression and the death of Charles Heater, Fred Heater decided to centralize the business in Gassaway, where it is headquartered today.In the early 1960s, Fred Heater's health was failing and he sold the business to his sons, John, William and James.When self-service gasoline pumps were legalized in West Virginia in 1970, the Heaters built the state's first self-service gas station, in Shinnston, and called it "Go-Tron."
