A flue heater is detachably secured to the flue of a chimney. The flue heater uses an electrical power source to create heat and direct the heated air into the lower portion of a flue. The device can be attached to the flue before igniting a fire and removed immediately prior to lighting a fire. The device can be used with any pre-existing chimney without the need for any large expense in retrofitting a permanent flue heater.
