The Thermistor can be used in several places around the boiler but are generally located on the flow or return pipes in the lower part of the boiler, inside the combustion chamber or attached to the heat exchanger outlet pipes. The Thermistor is an electrical component whose internal resistance changes with temperature variation. One end of the Thermistor is exposed to the heat source, and the other is the electrical connection. Some boilers have a flow and return thermistor, some also have a thermistor on the domestic hot water outlet pipe. The Thermistor can also be found checking the flue gas temperature on modern condensing boilers. Other common names for a Thermistor are, Temperature sensor or Negative Temperature Coefficient (NTC) Sensor. They can come as either a clip on sensor, push fit sensor or a screw fit sensor.
