History
The oil heating industry began with Petro, when M.A. Fessler invented the oil burner to take advantage of the crude oil that was seeping out of the CA ground in 1903. To capitalize on his invention, Fessler started the Fess System Company, which eventually became Petro. Fessler perfected his invention over the next several years, and in 1915 the company moved east, installing the first oil burner in Boston. The company then began to grow rapidly and by 1916 was entering into its first contracts to purchase fuel oil. By 1917, there were contracts to purchase over 210,000 gallons! Today
