Generally, a pellet heater uses a pellet raw material which is obtained by crushing a raw material such as wood and compression-molded to a predetermined size.

The pellet heater described above includes a pellet feeder for supplying the pellet fuel stored in the pellet storage container, a combustion unit for burning the supplied pellet fuel, a combustion chamber formed in the lower portion of the combustion unit, a roaster provided in the combustion chamber, And a reusing receptacle.

In the pellet heater thus configured, combustion is performed while pellet fuel is automatically supplied to perform operation by unmanned management.

In the conventional pellet heater as described above, since the roaster of the combustion chamber has a fixed structure, the ash of the pellet fuel is not discharged smoothly, resulting in incomplete combustion and incomplete combustion. 10-2010-0113927 discloses a rotary screw which is capable of pushing and discharging pellet fuel material whose combustion has been completed in the combustion chamber at regular intervals.

However, in the conventional pellet heater as described above, only the vicinity of the hearth is heated, so that the ceiling of the installation place or the roof of the multi-storey building is not heated.

In a conventional pellet heater, since the combustion chamber is horizontally arranged, the pellet fuel supplied to the combustion chamber is gathered and dispersed without being burned, so that the combustion power of each other is not concentrated and the combustion due to mutual heat generated in the combustion process is not performed. Unstable combustion occurs, and the pellet fuel is dispersed in the rotating process of the rotating screw discharging the ash, so that the burning power of the pellet fuel is lowered and the combustion is not clearly performed.

In addition, the conventional pellet heater has a problem in that waste of fuel is discharged because the pellets are discharged to the pellet fuel which has not been burned during the discharge process of the combusted material.
