Vaillant 103430 Heat Exchanger NTC Sensor - Genuine Vaillant part\n\n \n\nThe Vaillant 103430 Heat Exchanger NTC Sensor is a genuine replacement component designed for use in a wide range of Vaillant condensing boiler models, including the popular ecoTEC Pro, ecoTEC Plus, and VUW series. This NTC (Negative Temperature Coefficient) sensor plays a critical role in the boiler\u2019s heating system by continuously monitoring the temperature of the water flowing through the DHW heat exchanger. As the temperature changes, the sensor\u2019s electrical resistance varies, providing real-time feedback to the boiler\u2019s control board. This information allows the system to adjust burner output precisely, maintaining the desired water temperature while preventing overheating and maximizing efficiency.\n\nCrafted from durable, heat-resistant materials, the Vaillant 103430 sensor is engineered to withstand constant thermal cycling, moisture exposure, and vibration within the boiler hou.
