1. Heater
Thermistor in heater is utilized to set the optimal water temperature, and the energy of the input is effectively controlled. This thermistor not only needs to meet the sealed waterproof requirement, but also the fast thermal response. NTC thermistor can meet the both requirements. Therefore, NTC thermistor has been widely used in water heaters.  
2. Air conditioner
In recent years, NTC thermistor used in air conditioner has a rapid development. In general, this NTC thermistor is packaged with resin or encapsulated with copper shell, so it can meet the demands of moisture resistant, durable and power consumption.
