2. Working Principles of Electricity-Assistant Heating
Electric heating tube transfers the electric energy into the thermal energy, from which water will
absorb constantly and the temperature rises. When the temperature reaches the setting temperature,
the temperature control devices (which is on the PCB board) will shut off power supply automatically,
then the electric heating tube stops working. If dry-heating or over-heating phenomenon occurs, the
protection device non-self-resetting thermal cut-out will shut off immediately for protection.
