Comparative Heating Cost Analysis

Author: Paul Granberg, Issue: October 2004, Topic: Household

Kerosene Heater vs Conventional Electrical Heating


  • Kerosene costs approx 600 yen per 18 litre tank.
  • The fuel consumption of an average 3000 watt equivalent kerosene fan heater on full power is around 0.33 litres per hour.
  • Electrical charges are based on an average consumption of around 121 - 300 kWh per month. (i.e. 20.67 yen per kWh)
  • Electrical load of 1000W for an average electric heater.

Kerosene Heaters

  • 18 (litres per container) / 0.33 (litres per hour) = 54.54 (hours per container)
  • 600 yen (cost for 18 litres of fuel) / 54.54 (hours per container)

= 11.01 yen per hour of operation at full power(3000W equivalent).

  • 11.01 yen (per hour at 3000W equivalent) / 3

= 3.68 yen per kWh (equivalent) hour of operation)


  • Kerosene heaters = 3.68 yen per kWh
  • Electrical heaters = 20.67 yen per kWh


Kerosene heating is 5.62 times more cost efficient at home heating than electrical heating.
