ABSTRACT:
An improved rock heater having a hollow housing provided with a dome-shaped, heat conductive top and means therewithin for creating combustion gases. Means of heat conductive material is provided adjacent to the top for retaining a pile of rocks to be heated on the top, said retaining means having a fluid passage in fluid communication with the housing so that rising combustion gases, after heating the top, will pass into and through the retaining means. Thus, the heat energy from the top and retaining means will heat the rocks. Flue means coupled with the retaining means directs the combustion gases away from the housing. A shield surrounds the housing.
