PURPOSE: A complex heating apparatus is provided to reduce the use of oil and gas since a combustion type vaporizing pipe selects a downward vaporizing technique. CONSTITUTION: A complex heating apparatus comprises an oil/gas heater(A), an electric heater(B) and a hot blast(21). The oil/gas heater comprises a downward vaporizing spiral pipe(5), an internal combustor(11), an external combustor(12) and an internal case(13). The downward vaporizing spiral pipe receives the energy source from an oil feed pipe(17) or a gas feed pipe, is downwardly vaporized and combusted. The internal and external combustors combust the energy source, which is supplied from the downward vaporizing spiral pipe. The internal case covers the internal and external combustors. The electric heater is located on the upper end of the oil/gas heater. The hot blast is located on the lower end of the oil/gas heater and is electrically connected to the oil/gas heater and the electric heater to generate the hot wind.
