Thermistor

Gas or oil boilers heat the home using a fuel source. To ensure the safety of residents, each part includes a specific safety element.
The heating CTN ensures the hot water temperature is correct and the sanitary NTC prevents hot water from coming out of mixing or single-lever taps.
To avoid overheating in the heat exchanger, the thermistor is located near the heating exchanger.
This safety element is a klixon, meaning a heating spare part that trips at a certain temperature. For example, a 110-degree overheating safety klixon detects the temperature in the piping and informs the boiler's circuit board that overheating is occurring.
With the klixon for boilers, you avoid having to replace a boiler spare part or suffering from a boiler breakdown.
