Waste oil heater

When I was a kid in the '50's, probably 1/4 of the filling stations heated the office with a wood stove running off waste oil. They would put rocks in the stove, and drip oil from a copper tube on the rocks. To light it off, they would use a wad of newspaper. There would be a little black smoke coming from the chimney, not too bad. I don't remember a significant smell of oil burning in the office. The rocks would heat up and vaporize the oil to enable the combustion process. Don't use limestone, use something more refractory, like the pumice stone they sell at the plant places.

Probably not the same one but here is a link to the Mother Earth News waste oil heater plan.
No big trick to it. Drip the oil on something hot...

Michael, That link to the Mother Earth article was very informative. Thanks for posting it. I am planning a new garage/workshop right now and this may be a great way to heat it. Dennis
