<p>The purpose of the present invention is to increase the frequency of friction between fluids and the heating rate of a fluid by boosting turbulent flow in a head for heating a fluid using friction induced by rotation. To achieve this, a friction electric boiler head having a spiral water storage groove is connected to a motor to be rotated in a cylindrical heating space inside a case having an inlet and an outlet for a fluid in order to heat an incoming fluid and includes: a cylindrical body part having an opening on one side to face the inlet, an accepting space inside, and a motor connection part on the other side to be connected to the motor; and a friction blade protruding from the outer circumference of the body part to be arranged in multiple stages in the longitudinal direction, wherein each stage is partitioned by a double spiral water storage groove and a friction protruding part and a friction groove part are formed along the circumference of each stage.</p> |
