Abstract
An auxiliary heater is provided for heating a heat transferring fluid to a high temperature efficiently in a short time. The heater includes a permanent magnet provided within a housing and a rotary water jacket made of a conductor positioned to face the permanent magnet leaving a slight gap therebetween. The conductor generates slip heat when the water jacket is rotated in relation to the permanent magnet. The heat transferring fluid within the housing is heated by the slip heat generated in the conductor.
