A heating system (50) for heating a cabin (2) of an aircraft (1), said heating system including an annular heat exchanger (10) positioned around an exhaust pipe (21) of a turbine engine (20), and through which a heat transfer fluid (14) and ambient air (25) flow. Said heat exchanger (10) is provided with a rear casing situated at an outlet of said heat exchanger (10) and directing the ambient air (25) exiting form said heat exchanger (10) towards said exhaust gas (15) exiting via said exhaust pipe (21). Said exhaust gas (15) then generates a flow of ambient air (25) through said heat exchanger (10) by the “Coanda” effect. Said ambient air (25) flowing through said heat exchanger (10) is thus heated by convection from said pipe (21), and said heat transfer fluid (14) is heated firstly by radiation from said pipe (21) and secondly by convection between said heat transfer fluid (14) and said ambient air (25).
