In ST1, the user sets a desired temperature T0 from the operation unit 9. Then, the burner 3 of the combustor 2 is ignited to start combustion. At this time, in ST2, the room temperature T is compared with a preset operation switching temperature T1 (18 ° C. in the present embodiment) by the room temperature determining means 21.
When the room temperature T is lower than the operation switching temperature T1, the operation is switched to room temperature control I (ST3). When the room temperature T is higher than the operation switching temperature T1, the operation is switched to room temperature control II (ST4).

When the room temperature T rises to 18 ° C. or more, the operation mode is switched to ST4, and the normal heating operation means 2 is switched to ST4.

の室内温度分布が改善される。Thus, the room temperature T when the power is turned on is
Since it is lower than the so-called comfortable room temperature (it is said to be about 18 to 24 ° C), the warm air blown out from the heater rises due to the buoyancy caused by the difference in density between the indoor low-temperature air and the conventional air-conditioning operation. The temperature near the floor is less likely to rise. However, when the room temperature T is lower than 18 ° C., since the rotation speed (strong, medium) of the convection blower 5 is high with respect to the heating output (strong, medium, weak, fine) of the combustor 2, the air is blown out. The air volume is large, the convection of the air in the room is improved, the room temperature T can be raised and uniformed more quickly, and the room temperature distribution during heating is improved more than before.

が向上する。When the room temperature T becomes higher than 18 ° C., the number of revolutions (strong, medium, weak, fine) depends on the heating output (strong, medium, weak, fine).
(Medium, weak, fine) can be varied, so that at a comfortable room temperature, a quiet heating operation with a slight heating output and a slight rotation speed can be performed, and the comfort is improved.

れ、省エネルギー運転の効果が期待できる。In particular, when the set temperature T0 is set to about 18 ° C. for the purpose of energy saving operation, the heating output decreases as the room temperature T approaches the set temperature T0 in the conventional heating method, and the rotation of the convection blower 5 is increased. Since the number was small, the rise of the room temperature T was slow, and the deviation of the room temperature distribution was large. At a setting of 18 ° C., there was a feeling of cold and warm, and energy saving operation was not much liked. However, according to this embodiment,
Even when the set temperature T0 is 18 ° C., the convection of the indoor air is enhanced, and the indoor temperature distribution is improved, so that the feeling of cool and warm is improved and the effect of energy-saving operation can be expected.
