The flue gases additionally give off heat to this casing, which stores up the heat and gradually gives it off to the air in the room. In this way an approximately constant oil feel pressure to the burner is ensured. From the control tank the oil flows through a control valve which can be set to deliver the oil to the burner at a certain rate. By varying the valve setting, the heat output of the stove can be regulated. The burner is usually of the pot types, in which the oil first vaporizes as a result of coming into contact with the hot walls of the combustion chamber.
Combustion air flows into the chamber through holes, and the oil vapour burns continuously.
The hot gases of combustion flow upwards and heat the combustion chamber walls. These in turn gives off their heat to the air in the room. Some stoves are equipped with small fans to assist the flow of combustion air, making this largely independent of chimney draught. The fuel used is a relatively light fuel oil.
