ABSTRACT:
An air heating and ventilation system particularly suitable for well-insulated and draught-proof dwellings or buildings, there being provided a supply duct for fresh external air, connected to a main fan, a combustion chamber with an exhaust duct for the flue gases, an air heater disposed in the combustion chamber, a main distribution duct, feed ducts with controllable terminals for the rooms, a dirty air discharge duct provided with a fan, and a heat exchanger disposed between the supply duct for the outside air and the exhaust duct for the flue gases. The dirty air discharge duct is connected to the combustion chamber, so that dirty air at least in part acts as air for combustion and the remaining part is discharged together with the flue gases via the heat exchanger, the latter being adapted for transmitting the resulting condensate to the incoming external air.
