The invention relates to the technical field of heating, and discloses an energy-saving heating bed which comprises a bed board. Bed legs are fixedly connected with the left side and the right side ofthe lower surface of the bed board. A heat supply frame is arranged between the two bed legs. A central heating pipe is arranged at the bottom of the heat supply frame. The left side of the heating frame is fixedly connected with a second driving motor. An output shaft of the second driving motor is fixedly connected with a third bevel gear. The third bevel gear is meshed and connected with a fourth bevel gear. The fourth bevel gear is fixedly connected with the left end of a lead screw. The left side and the right side of the lead screw are in threaded connection with sliders. Baffles are hinged to the upper portions of the sliders. A fixed block is rotationally connected with the middle of the lead screw. Baffles are hinged to the left side and the right side of the upper portion of thefixed block. The baffles at the upper portions of the sliders and the baffles at the upper portion of the fixed block are rotationally connected through rotating shafts. The energy-saving heating bedis suitable as the central heating bed; the lead screw rotates to drive the two sliders to move left and right and adjust the size of openings of heating holes, and therefore the temperature of a bedboard is adjusted, the personalized adjustment of the temperature of the bed board is realized, and the energy-saving heating bed is more user-friendly.
