What is NTC?
An NTC or ‘Negative Temperature Coefficient’ is a type of thermistor (or thermal resistor).
Basically, it’s an electrical component that helps to regulate the temperature of your boiler. So, when you set your heating to a certain temperature it will make sure your boiler stays at that temperature.
