This heater takes in the air necessary for combustion from outside the room through the air flue pipe, and exhausts the combustion gas to the outside through the air flue pipe. Unlike kerosene heaters and kerosene fan heaters, these heaters require installation work on the wall, but they do not pollute the air in the room during heating and do not require ventilation.
