There are two simple ways to increase the heating speed of electric heater:
1. Diode half wave rectifier is used to change the effective value of alternating current, so as to change the heating power and heating speed. This method is widely used, and its advantage is simple circuit structure and convenient operation.
2. Voltage transformation, using small transformer to transform voltage, the advantage is that it can be adjusted in multiple gears, the disadvantage is that the circuit structure is complex and the production cost is high.
