What can a defective oil cut-off valve potentially lead to in a heating unit?

Efficient operation
Uneven heating
Leakage on the floor
Odorless emissions

The correct answer is: Leakage on the floor

A defective oil cut-off valve can lead to significant issues in a heating unit, particularly concerning safety and operational integrity. When this valve malfunctions, it may fail to stop the flow of oil when the heating unit is turned off or during a fault condition. This failure can result in an oil leak, which poses risks such as fire hazards and environmental contamination. Moreover, leaks on the floor can create unsafe working conditions, leading to slips or the potential ignition of oil vapors. It is crucial for the oil cut-off valve to function correctly as it plays a critical role in preventing uncontrolled oil discharge and ensuring the heating system operates safely and efficiently.
