The invention discloses an energy-saving heating device provided with a movable temperature-measuring system and a method. The energy-saving heating device comprises a positioning device, a temperature-measuring device, a coordination control system and a heating device; the positioning device is used for positioning a human body and transmitting positioning information to the coordination controlsystem; the temperature measurement device measures the temperature of ambient environment of the human body and transmitting temperature information to the coordination control system; the coordination control system receives the position information and temperature information of the human body; one or a plurality of heating devices which need to work are controlled to move to a prescribed position according to the position information of the human body by the coordination control system; the temperature measuring device measures the temperature of the ambient environment of the human bodyin real time and transmits the temperature information to the coordination control system, and the coordination control system adjusts the working powers of the heating devices according to current temperature; by adopting the energy-saving heating device, the human in a region can e positioned, and the temperature of the ambient environment of the human body can be measured; the heating devices move near the human, and heat the ambient zones of the human directly; and an automatic tracking heating function is realized.
