How long can you run a kerosene heater?

The runtime of a kerosene heater depends on several factors, including the heater's fuel capacity, the heating setting, and the ambient temperature. Here are some general guidelines:

1. Fuel Capacity: The runtime of a kerosene heater is primarily determined by the size of its fuel tank. Most indoor kerosene heaters have tanks that range from 1 to 2 gallons (3.8 to 7.6 liters). Larger tanks can provide longer runtime before requiring refueling.

2. Heating Setting: The runtime will also vary depending on the heat output setting of the heater. Higher heat settings consume fuel more quickly and result in shorter runtime, while lower settings conserve fuel and extend the heater's operation time.

3. Ambient Temperature: In colder environments, the heater may need to run for longer periods to maintain a comfortable indoor temperature. Warmer temperatures require less heating and can extend the runtime of the heater.

4. Efficiency: The efficiency of the kerosene heater can impact its runtime. High-quality heaters with efficient combustion systems may use fuel more effectively, resulting in longer operation times.

5. Ventilation: Proper ventilation is crucial when running a kerosene heater indoors. Inadequate ventilation can lead to incomplete combustion, increased fuel consumption, and potentially harmful carbon monoxide buildup. Ensure that the room has sufficient airflow to safely operate the heater.

As a rough estimate, a typical indoor kerosene heater with a 1 to 2-gallon fuel tank can run continuously for approximately 8 to 12 hours on a full tank, depending on the factors mentioned above. However, it's essential to monitor the heater's fuel level regularly and refill it as needed to prevent running out of fuel unexpectedly. Additionally, always follow the manufacturer's recommendations and safety guidelines when operating a kerosene heater to ensure safe and efficient operation.
