As the weather turns to cold days and nights we look for ways to add supplemental heating. Many people use kerosene heaters though I rarely recommend them. If you want to use this type of heater make sure that the room has proper ventilation. When refueling your heater, make sure that it has cooled down and that the process takes place outside. You should only use crystal clear K 1 kerosene. Any other type of fuel is asking for big problems including an explosion in your home. The wick on the heater should be checked every few weeks during the heating season. If the wick is found to be dirty clean or replace it. Kerosene heaters do have an open flame, it should never be used in a room where there are flammable solvents, aerosol sprays, gasoline or any type of oil.
