The problems that a mixing heater is low in heat transfer efficiency, and potential safety hazards are likely to occur are solved. The utility model provides a hybrid heater. The heater mainly comprises a heater shell, the lower part of the heater shell is connected with a drain pipe; a steam pipeline main pipe, a plurality of sets of steam pipeline branch pipes fixedly connected to the lower portion of the steam pipeline main pipe and steam injection pipes connected to the lower portions of the steam pipeline branch pipes are arranged in the heater shell. The steam pipeline main pipe is arranged above the highest water line in the heater shell through a supporting device; a steam conveying pipe which extends out of the heater shell and is used for conveying heating steam into the steam pipeline main pipe is connected above the steam pipeline main pipe; each set of steam pipeline branch pipes is of an inverted-V-shaped structure, a plurality of through holes are formed in the portion,above the highest water line, of the pipeline, and a plurality of spraying holes which are arrayed along the outer surface in a spiral line mode are formed in the steam spraying pipe.
