Our Expert's Opinion
“A temperature sensor that accurately monitors hot water output to ensure safe, consistent, and efficient boiler performance.”Glow-Worm S5720200 Domestic Hot Water Sensor
As a Glow-Worm spare part, the S5720200 sensor is manufactured to original equipment specifications, ensuring precise temperature readings, correct electrical compatibility, and long-term reliability in demanding operating conditions. The sensor plays a critical role in the boiler’s safety and efficiency by continuously communicating temperature data to the control board, allowing the system to adjust flame output and water flow in real time. If the sensor becomes inaccurate or fails, the boiler may produce inconsistent hot water temperatures, experience overheating issues, or display fault codes that disrupt normal operation.
Over time, domestic hot water sensors can degrade due to mineral scale build-up, prolonged exposure to heat, or electrical wear, which can cause incorrect readings or complete sensor failure. Replacing a faulty sensor with this OEM component restores accurate temperature regulation, improves user comfort, and helps protect internal components from thermal stress. Proper installation by a qualified heating engineer ensures the sensor is correctly positioned, securely connected, and fully compatible with the boiler’s control system, maintaining safe and efficient hot water performance.
