In the above configuration, when the switching means 32 switches the airflow from the blowing means 29 to the radiating means cooling air passage 26 side, the radiant heating operation is performed, the entrance of the radiating means cooling air passage 26 is opened, and the blowing means is opened. 29 flows into the radiating means cooling air passage 26, and the combustion exhaust gas generated in the combustion section 21 loses its downward flowing force.
, And flows further upward due to the draft by the heat, and is guided to the radiator heating air passage 24.

Then, the heat collecting surface 25 of the radiator 23 is heated to a high temperature by the high-temperature flue gas generated in the combustion section 21, and the heat collected by the heat collecting surface 25 is generated as radiant energy from the radiator 23. You will be able to heat it.

That is, since the amount of radiant energy generated from the radiator 23 is made to fluctuate depending on the intensity, the user receives a change in the amount of radiant energy generated from the radiator 23 and becomes aware of the feeling of heating. Therefore, the comfort of the heating sensation due to the radiation of the user is increased, and at the same time, the average heating capacity can be gradually reduced slightly without the user feeling uncomfortable, and energy saving can be achieved.

In the above embodiment, the circulating air supply means is described as using the air supply means 29 for supplying an air flow which is mixed with the high-temperature gas from the high-temperature gas generation means and discharged as hot air. Structure and radiator 2
