The invention relates to an efficient stream generation device achieving vertical heating.The device comprises a tubular heater, a balanced water tank, a balanced water tank water inlet, a balanced water tank pumping opening, a water replenishing water tank, a water replenishing tank water inlet, a steam container and a steam outlet; the tubular heater is vertically arranged between the steam container and the balanced water tank, the two ends of the tubular heater are communicated with one end of the steam container and one end of the balanced water tank respectively, the balanced water tank is communicated with the steam container, and the balanced water tank is provided with the balanced water tank water inlet.According to the steam generation device, due to the fact that the balanced water tank, the water replenishing water tank and a water level sensor are arranged, the appropriate water volume is kept in the tubular heater, steam can be generated rapidly, and meanwhile excessive dry combustion of heating elements is prevented.By means of the balanced water tank and an overflow port, the height of the water level in the tubular heater is kept to be the height of the overflow port, and the stability and high efficiency of steam generation are guaranteed.
