Quick Answer
Kerosene heaters generally produce between 5,000 to 20,000 BTUs of heat output, while electric heaters typically produce between 1,000 to 5,000 watts, or approximately 3,412 to 17,056 BTUs, depending on the model and efficiency.
Comparison of Kerosene and Electric Heater Efficiency
Kerosene heaters are often more efficient than electric heaters, with a typical efficiency of 30% to 50% compared to an electric heater’s 100% efficiency. However, kerosene heaters also require a fuel source and can produce toxic fumes, so they’re not ideal for indoor use. In contrast, electric heaters are electrically efficient but often have lower heat output and may consume more power.
Heat Output and BTU Measurements
When comparing heat output between kerosene and electric heaters, it’s essential to consider the BTU (British Thermal Unit) measurement, which represents the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit. Kerosene heaters typically use a BTU rating to measure heat output, while electric heaters use watts or kilowatts. To make a direct comparison, consider the following approximate BTU values: 1,000 watts = 3,412 BTUs, and 1 gallon of kerosene = approximately 135,000 BTUs. This means a 5,000 BTU kerosene heater could be equivalent to a 1,460-watt electric heater.
