What fuel can you run a space heater on?

Space heaters can run on various fuels, including electricity, natural gas, propane, and kerosene. Electric space heaters are the most common and are typically used for indoor heating. Gas heaters, such as those powered by natural gas or propane, are often found in areas where electricity is less accessible. Kerosene heaters are portable and can be used in emergencies, but they require proper ventilation due to emissions.
