A pellet stove or grill includes a housing (10) divided by a thermal barrier (43), which is defined by a spaced pair of partitions (20, 21), into a hot compartment (23) and a cold compartment (47). The hot compartment includes a ventilated firepot (44) suspended within an air channel (40) that communicates with the cold compartment through the thermal barrier. The cold compartment is subdivided by a funnel (22) into a fuel pellet storage compartment (24) thereabove and an electrical compartment (25) therebelow. The electrical compartment includes a motorized, fuel conveyer (37) for feeding fuel pellets (31 ) from the storage compartment, down a chute (38) that extends through the thermal barrier, and into the firepot in the hot compartment for combustion. The chute includes a portion that is positioned within and communicates with the thermal barrier. An air blower (34) drives fresh air into the electrical compartment and into the thermal barrier through an aperture (50) in one of the partitions. The air is conducted directly from the thermal barrier into the chute and then into the hot compartment. Thus air is continuously being circulated through the thermal barrier to cool it, thereby insulating the cold compartment, which stores the fuel pellets and houses the electrical components, from the heat generated in the hot compartment.
