ABSTRACT:
An oil heater comprises an oil burning section and an oil feeding system for feeding oil from a tank to the burning section. 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. The combustion detecting means is connected to the relay means to allow electric current to pass through the relay means from the electric source to the motor means only when the detecting means detects combustion of oil.
