Also known as an NTC temperature sensor, they monitor the temperature of the central heating water and also the domestic hot water, by sending a signal to the main printed circuit board which in turn reduces the amount of gas that is being delivered to the burner hence reducing the amount of gas being used and making the boiler more efficient.

Thermostats are safety devices which are fitted to all boilers, they are also referred to as limit stats, control stats and overheat stats. The control thermostat normally sits behind the control knob at the front of the boiler The thermostat is a control on the boiler that enables you to change or set the temperature of your central heating system most of the other thermostats are located inside the boiler and monitor temperature. If excessive temperatures are detected the thermostats turn off the boiler and normally have to be re-set to allow the boiler to work again.
