Our Expert's Opinion
"A temperature-sensing thermistor that supports boiler safety during low or no-flow conditions."Ideal 175594 Thermistor No Flow
Accurate temperature sensing is essential for protecting a boiler during abnormal operating conditions, such as restricted circulation caused by airlocks, closed valves, or pump-related issues. The no-flow thermistor allows the control system to detect rapid temperature rises when water movement is limited, enabling the boiler to reduce output or shut down if necessary. This protective function helps safeguard critical components such as the heat exchanger and pump, reducing the risk of thermal stress, damage, or premature wear.
Over time, thermistors may degrade due to prolonged exposure to heat, scale build-up, or electrical fatigue, which can result in inaccurate temperature readings or intermittent signals. Symptoms of a failing no-flow thermistor may include overheating faults, unexpected boiler shutdowns, or error codes related to temperature sensing. Replacing a worn or faulty thermistor helps restore accurate temperature monitoring, improves system protection, and supports reliable boiler operation. Because this component influences safety-related control decisions, installation and testing should always be carried out by a qualified heating engineer, ensuring correct positioning, secure connections, and proper system response.
