The oil feeding system includes pump means and motor means for operating the pump means. A control system of the oil feeding system consists essentially of relay means situated in a line between the motor means and electric source, combustion detecting means provided in the burning section to detect combustion of oil, and thermoresponsive switch means situated in the line between the relay means and the electric source for operating the relay means and the detecting means after combustion of oil in the burning section.
