Ntc Sensor For Baxi Boiler-New

The Baxi NTC sensor 5114725 helps your boiler monitor water temperature accurately, so it can manage heating and hot water performance correctly. However, if the sensor fails or gives incorrect readings, the boiler may cycle poorly or show temperature-related faults. Therefore, replacing it with a brand new part helps restore accurate temperature control, improve efficiency, and support smooth daily operation.
