What device circulates oil throughout the heating system?

Oil strainer
Flow meter
Suction cup
Pressure gauge

The correct answer is: Suction cup

In a heating system, the correct device responsible for circulating oil throughout the system is commonly referred to as a pump, and while "suction cup" might suggest some function related to moving or drawing, it does not accurately describe the action of circulating oil. Pumps facilitate the movement of oil by creating a flow, ensuring that the heating elements receive a continuous supply of oil for effective operation. The oil strainer serves to filter impurities from the oil before it enters the system, while the flow meter measures the quantity of oil flowing through the system without influencing circulation. The pressure gauge monitors the pressure of the oil within the system but does not circulate it. Hence, while the question does not list 'pump' as an option, the correct understanding of the role of pumps in circulating oil is essential for effective operation in a heating system.
