Considering these, the running cost per hour is considered to be 13 yen to 75 yen. ■ Oil fan heater Let's consider the unit price of kerosene at 100 yen. Oil fan heaters require power for combustion and hot air, so they cannot operate with kerosene alone, but the power consumption is very small, about 10W to 20W.
