What kind of equipment utilizes oil for heating or cooking?

The option that identifies equipment utilizing oil for heating or cooking is indeed the one focused on oil burning equipment. This category specifically refers to systems designed to burn oil as a fuel source for generating heat, which is often used in residential or commercial settings. Oil burning systems typically include oil furnaces and boilers, which convert oil into heat through the combustion process.

In contrast, electric heaters rely on electrical energy to produce heat; gas burners use natural gas or propane for combustion; and heat pumps function by moving heat rather than generating it through combustion, making them suitable for both heating and cooling. These distinctions are essential for understanding various heating methods and the specific fuel sources they require.
