FIELD: hot air supply for domestic and industrial use. SUBSTANCE: air is forced through inlet and outlet gauze walls by axial- flow fan and heats up when coming in contact with thermoelectric heating elements. Fan and motor are placed in flow channel of housing. The latter is not obstructed by any parts and air stream is free to change its direction of flow. Heater is provided with perforated surface and layer of noise-absorbing wool. EFFECT: reduced water loss which raises heater efficiency; reduced size and improved environmental friendliness of heater. 2 dwg
