The invention relates to a household direct-fired heating appliance using compressed straw as fuel. The household direct-fired heating appliance comprises a heating furnace and an automatic feeder, which form an H-shaped structure and which are connected through a material pass. The upper structure of the heating furnace comprises the material pass, a smoke pass, a smoke window, a water jacket, a water-cooled grate, a convection bank, a balance tube, a water-cooled partition, an anti-radiation retainer, and a waste heat recovery water jacket. The lower structure of the heating furnace comprises a rocking grate, a combustion pass, a secondary air chamber, an insulation layer and an ash hopper. A combustion chamber comprises a main chamber and a secondary chamber. The automatic feeder comprises a speed control motor, a coupling, a screw, stirring blades, a tray, rollers, a limiting switch, a control circuit box, a motor box, and a fuel box. The automatic feeder can continuously and automatically convey the compressed straw for 12 hours; the compressed straw slips into the heating furnace through the material pass; the heating furnace combusts efficiently and stably. The household direct-fired heating appliance is high in combustion efficiency, low in pollutant emission, simple to operate, low in cost and widely applicable.
