The National Oil Heating Company offered its steam automobile for sale in 1902. It later focused on its National Kerosene Oil Burner as an aftermarket product.
Its advertising starts in 1902 and runs through 1904, when it was apparently acquired or merged into the Melrose Automobile Company that occupied its Melrose factory.
This four-page trade catalogue, ca: 1902, features the steam car produced by the National Oil Heating Company as well as its kerosene burning burner.
The National Oil Heating Company's August 1903 advertisement in Horseless Age does not mention its steam car, only its kerosene burner.
"The National Kerosene Burner has no peer," according to this April 1905 advertisement in the Cycle & Automobile Trade Journal.
As time progressed, the size of the National Oil Heating Company's advertisements kept getting smaller and smaller.
By April 1906, it may have merged with the Melrose Automobile Company, which ran an article proclaiming the superiority of the National Kerosene Burner in Fred Marriott's race car.
