Can Kerosene Heaters Be Used As Supplemental Heat During Winter?

April 5, 2026

Quick Answer

Kerosene heaters can be used as supplemental heat during winter, but they should be used with caution and follow proper safety guidelines.

Choosing the Right Kerosene Heater

When selecting a kerosene heater for supplemental heat, consider models with safety features such as automatic shut-off, overheat protection, and tip-over safety. A 10,000 to 15,000 BTU kerosene heater is a suitable size for a small living space, while a 20,000 to 30,000 BTU model can heat larger areas. Always choose a heater that is certified by a reputable testing organization, such as UL (Underwriters Laboratories) or CSA (Canadian Standards Association).

Safety Precautions

To use a kerosene heater safely, ensure proper ventilation in the room by opening windows or using a fan to circulate air. Keep the heater at least 3 feet away from flammable materials, such as curtains, towels, or furniture. Never leave a kerosene heater unattended or running while asleep, and always follow the manufacturer’s instructions for maintenance and troubleshooting. It’s also essential to store kerosene in a well-ventilated area, away from heat sources and open flames.

Operating a Kerosene Heater Efficiently

To maximize the efficiency of a kerosene heater, use the correct type of kerosene, which is typically marked as “K-1” or “D-1”. Keep the heater clean and well-maintained by regularly checking and replacing the wick, cleaning the fuel tank, and ensuring proper airflow. By following these guidelines, you can safely and effectively use a kerosene heater as supplemental heat during the winter months.
