Abstract
A stack-equipped far infrared space heater capable of permitting a space of a relatively large volume through which hot air for fan forced space heating fails to carry well to be satisfactorily heated by far infrared rays. The space heater includes a combustion cylinder mounted on a burner arranged in a housing, a plurality of heat-exchange pipes arranged on the combustion cylinder, and a cylindrical exhaust structure arranged on the heat-exchange pipes. A guard is arranged on the housing so as to surround the combustion cylinder and cylindrical exhaust structure and mounted thereon with a top plate, which is formed at a central portion thereof with an opening. An upper wall of the cylindrical exhaust structure is fitted in the opening and securely fixed to the top plate through fixtures. A stack is connected to a side wall of the cylindrical exhaust structure so as to upwardly extend therefrom through a bent cylinder. The parts or components extending from the combustion cylinder to the stack are constructed integrally with each other to exhaust combustion gas by drafting force in the stack.
