The utility model discloses a blast heater of energy saving and environmental protection, possessing the characteristic of effective reducing of energy consumption. The blast heater comprises a blower fan and a heating pipe with an inlet and an outlet. An outlet of the blower fan is connected with the inlet of the heating pipe; electromagnetic induction coils are arranged at the heating pipe; and the electromagnetic induction coils are electrically connected with alternating current power supply. When the electromagnetic induction coils are employed to make the heating pipe emit heat, the heating pipe does not need other heating units to emit heat, but emits heat relying on a self resistor under the effect of an electromagnetic field. No space medium exists, so that heat loss during the heat conducting process and electric energy loss of heating elements do not exist, and energy is substantially saved. At the same time, the electromagnetic induction coils do not generate heat, so that electric energy loss is
