ABSTRACT:
A heater comprising a heater body containing a heating source; an air blower for forcibly blowing off heated air from the heater body into a room, the heated air being produced by heat-exchanging with the heating source; a first temperature detection element for detecting a temperature at an upper level in the room; a second temperature detection element for detecting a temperature at a lower level in the room; a sensation input means for enabling a user to input his or her sensation corresponding to an actual room temperature; means for determining heating capability of the heating source based on the difference between the temperature detected by the first temperature detection element and a first set temperature; means for changing the outlet area and/or the air volume of the heated air based on the difference between the temperature detected by the second temperature detection element and a second set temperature lower than the first set temperature to determine the blow-off speed and/or the air volume of the heated air; and a control means for changing the first set temperature and the second set temperature based on the input given through the sensation input means.
