The present invention relates to a wooden pellet heater comprising: a housing of a cylindrical shape to form a combustion chamber having a combustion hole, an exhaust hole, and a combustion ash outlet; a fire grate having a container form detachably installed on the combustion hole to charge and combust the wooden pellet fuel; a hopper mounted on the housing to continuously supply the wooden pellet fuel to the fire grate through a supply hole connected to the combustion hole; an inner pipe installed on the housing to connect with the exhaust hole; a heating duct having a connection hole to surround the inner pipe to form a heating space in the housing; and an exhaust pipe installed on an outer side of the heating duct to connect with the connection hole of the heating duct. According to the present invention, the wooden pellet heater is able to further improve the heating capability and efficiency by increasing the exhaustion efficiency with the fire grate and the structure thereof and the thermal efficiency by a dual exhaust pipes structure. Additionally, the present invention achieves convenience and economic efficiency with reduced manufacturing cost and lightweight, by allowing efficient supply of combustion air without need of an additional power system to blow air into the combustion chamber, capable of easy installation and moving for both indoor and outdoor areas, in addition to a hot water supplying capability. |
