PURPOSE: To remarkably increase a surface area of a heater, to improve a room heating efficiency and to reduce in size a room heater body which produces a high output by using a conductive honeycomblike ceramic molded form as a heating unit of the heater.
CONSTITUTION: A ceramic heater 11 made of honeycomblike ceramics having conductivity, is assembled in a heater unit 10, and mounted in a body 1. A blow-off port 4 is provided at the upper part of the body 1, and a suction port 5 is provided at the lower part. A conductive honeycomblike ceramic molded form which is baked in a porous state, is used, and noble metal particles are catalyst-carried on the surface. The heater 11 is energized to generate heat, thereby heating the air around the heater. The heater 11 is formed in the honeycomblike state to increase its surface area thereby to enhance heat exchanging capacity with the air, and even if the heat generating temperature of the heater 11 is suppressed to 500°C or lower which is not red-heated, the temperature of the passed air becomes high.
