A system and method for distribution of heated air in a selected area, for example the cabin of an engine powered craft such as a helicopter, is disclosed. The heat distribution system includes a main hot air supply conduit connected to the engine compressor of the engine for receipt therethrough of hot bleed air from the engine, a zone supply conduit having a plurality of outlets, a main control valve connected between the main supply conduit and the zone supply conduit for controlling the volume of hot air passing therethrough from the main supply conduit to the zone supply conduit, and a plurality of heated air distribution units for selectively controlling the volume of hot air released into the units through the zone supply conduit outlets and for mixing the hot air with air at ambient temperature received at the units for thus distributing heated air from the units to different zones in the selected area. In a helicopter, a portion of the mian supply conduit, the zone supply conduit, the main valve and the distribution units are located under the forward facing pilot and passenger seating units and in the center console dividing the seating units and are spaced from helicopter controls located thereat to thus enhance safety and accessibility of the system and system controls installed in the helicopter.
