The Bunsen Sports Heater was made by the Sports Heater Co, Denver, CO, in the 1960's and 1970's. The exact date at which production ceased is unknown.
In effect, the Bunsen Sports Heater operates using the same combustion principles as a Victorian Era center draft lamp, only done all in metal with multiple safety screens which inhibit areas which would be so hot as to be unsafe. Unlike other Bunsen heaters, no asbestos wicking is used in the Sports Heater.
The custom-made wick for the Bunsen Sports Heater is shipped with complete, illustrated installation instructions.
