An electric heating module includes an electric heater ( 10 ), a heat pipe ( 20 ) having an evaporating section ( 22 ) thermally attached to the electric heater and a condensing section ( 24 ), and at least one heat radiator ( 30, 40 ) thermally attached to the condensing section. The electric heater includes a pair of electrode plates ( 12, 14 ) and a heating element ( 16 ) sandwiched between and electrically connecting the electrode plates. An insulation frame ( 19 ) encloses the electrode plates therein for electrically insulating the electric heater from the heat radiator. For the non-linear PTC heating element, the electric heater can rapidly heat up to and stay at a desired stable temperature. The heat pipe can transfer heat from the electric heater to the heat radiator rapidly and timely by phase change.
