Abstract: PURPOSE: To compact structure by heating a gaseous heating medium by a second heat exchanger circulated with heated liquid heating medium to perform heating, in an automotive heater equipped with a burner surrounded by a heat exchanger for heating the liquid heating medium. CONSTITUTION: This heater 1 has a closed type liquid circulation path composed of space parts 2-4 communicated with each other, and arranges a liquid fuel actuation type burner 5 in a first space part 2. The burner 5 generates high- temperature combustion gas in a combustion chamber 6, and the gas is direction- converted at the end part of the chamber 6 being in the opposite side to the burner 5 to be flowed down in an intermediate space part being between the chamber 6 and a heat exchanger 8 surrounding the chamber 6, thereby being exhausted from an exhaust gas outlet 9. The space parts 3 and 4, provided with an outlet connection part 13 and an inlet connection part 14 respectively, are communicated with the above space part 2, and a liquid heat exchange medium is circulated with an air heating heat exchanger 10 between, thereby heating and blowing off air as warm air into a car room.
