PROBLEM TO BE SOLVED: To conduct supply of kerosene merely by replacing a sealed metal can. SOLUTION: A metal can receiver 2 is formed at a kerosene receiving container 1, a piercing part 3 for piercing a bottom of a charged sealed metal can 8 is formed at the can receiver 2. The part 3 is provided at a specified oil level height of the container 1 so that the supply of the kerosene does not exceed the height. A metal can retainer 10 is provided so that the can 8 may not be wastefully fluctuated, and a kerosene receiving volume of a part exceeding the height of the container 1 can be sufficiently contained at least in the sealed can of full volume of the kerosene. In this case, when an oil level meter is abnormally raised in addition to the specified oil level height, this is displayed or in the case of the oil supply request state, that is displayed, thereby expediting a necessary countermeasure prudently for handling the heater.
