Home heating oil is a type of fuel that is used to heat homes and buildings. It is a liquid fuel that is typically made from petroleum, and it is stored in a tank at the home or building. To use it for heating, the fuel is pumped from the storage tank into a furnace or boiler, where it is burned to produce heat. The heat is then distributed throughout the home or building using a system of ducts or radiators.

Heating oil is a popular choice for heating homes in certain parts of the world, particularly in rural areas. It is generally more affordable than natural gas and can be a good option for homes that are not connected to the natural gas grid. However, it can be more expensive to use than other types of fuel, such as electricity, and it can also be more expensive to install and maintain the necessary equipment.
