The top end of each of the water pipes 11 is open, and each of the water pipes 11 communicates with each other at the bottom to form a communicating body.

One end of the communicating device communicates with the preheating water pool 30 through a water pipe I. The water pipe I is provided with a water pump 40; the other end of the communicating device communicates with the heating chamber through a water pipe II, and a water valve 50 is mounted on the water pipe II.

The condensing preheating chamber 10 is also connected to a portion of the condensate drain pipe 70 built into the preheating water tank 30, and the condensate drain pipe 70 extends out of the preheating water tank 30. The condensing preheating chamber 10 communicates with the heating chamber 20 through a steam conduit 22, An air valve 60 is mounted on the steam pipe 22. Preferably, the condensing preheating chamber 10 can communicate with the plurality of heating chambers 20 through a plurality of water pipes and a plurality of steam pipes.
